Prodigious substrate specificity of AAC(6')-APH(2"), an aminoglycoside antibiotic resistance determinant in enterococci and staphylococci. (1/34326)

BACKGROUND: High-level gentamicin resistance in enterococci and staphylococci is conferred by AAC(6')-APH(2"), an enzyme with 6'-N-acetyltransferase and 2"-O-phosphotransferase activities. The presence of this enzyme in pathogenic gram-positive bacteria prevents the successful use of gentamicin C and most other aminoglycosides as therapeutic agents. RESULTS: In an effort to understand the mechanism of aminoglycoside modification, we expressed AAC(6')-APH(2") in Bacillus subtilis. The purified enzyme is monomeric with a molecular mass of 57 kDa and displays both the expected aminoglycoside N-acetyltransferase and O-phosphotransferase activities. Structure-function analysis with various aminoglycosides substrates reveals an enzyme with broad specificity in both enzymatic activities, accounting for AAC(6')-APH(2")'s dramatic negative impact on clinical aminoglycoside therapy. Both lividomycin A and paromomycin, aminoglycosides lacking a 6'-amino group, were acetylated by AAC(6')-APH(2"). The infrared spectrum of the product of paromomycin acetylation yielded a signal consistent with O-acetylation. Mass spectral and nuclear magnetic resonance analysis of the products of neomycin phosphorylation indicated that phosphoryl transfer occurred primarily at the 3'-OH of the 6-aminohexose ring A, and that some diphosphorylated material was also present with phosphates at the 3'-OH and the 3"'-OH of ring D, both unprecedented observations for this enzyme. Furthermore, the phosphorylation site of lividomycin A was determined to be the 5"-OH of the pentose ring C. CONCLUSIONS: The bifunctional AAC(6')-APH(2") has the capacity to inactivate virtually all clinically important aminoglycosides through N- and O-acetylation and phosphorylation of hydroxyl groups. The extremely broad substrate specificity of this enzyme will impact on future development of aminoglycosides and presents a significant challenge for antibiotic design.  (+info)

Mechanism and specificity of the terminal thioesterase domain from the erythromycin polyketide synthase. (2/34326)

BACKGROUND: Polyketides are important compounds with antibiotic and anticancer activities. Several modular polyketide synthases (PKSs) contain a terminal thioesterase (TE) domain probably responsible for the release and concomitant cyclization of the fully processed polyketide chain. Because the TE domain influences qualitative aspects of product formation by engineered PKSs, its mechanism and specificity are of considerable interest. RESULTS: The TE domain of the 6-deoxyerythronolide B synthase was overexpressed in Escherichia coli. When tested against a set of N-acetyl cysteamine thioesters the TE domain did not act as a cyclase, but showed significant hydrolytic specificity towards substrates that mimic important features of its natural substrate. Also the overall rate of polyketide chain release was strongly enhanced by a covalent connection between the TE domain and the terminal PKS module (by as much as 100-fold compared with separate TE and PKS 'domains'). CONCLUSIONS: The inability of the TE domain alone to catalyze cyclization suggests that macrocycle formation results from the combined action of the TE domain and a PKS module. The chain-length and stereochemical preferences of the TE domain might be relevant in the design and engineered biosynthesis of certain novel polyketides. Our results also suggest that the TE domain might loop back to catalyze the release of polyketide chains from both terminal and pre-terminal modules, which may explain the ability of certain naturally occurring PKSs, such as the picromycin synthase, to generate both 12-membered and 14-membered macrolide antibiotics.  (+info)

A genetic model of substrate deprivation therapy for a glycosphingolipid storage disorder. (3/34326)

Inherited defects in the degradation of glycosphingolipids (GSLs) cause a group of severe diseases known as GSL storage disorders. There are currently no effective treatments for the majority of these disorders. We have explored a new treatment paradigm, substrate deprivation therapy, by constructing a genetic model in mice. Sandhoff's disease mice, which abnormally accumulate GSLs, were bred with mice that were blocked in their synthesis of GSLs. The mice with simultaneous defects in GSL synthesis and degradation no longer accumulated GSLs, had improved neurologic function, and had a much longer life span. However, these mice eventually developed a late-onset neurologic disease because of accumulation of another class of substrate, oligosaccharides. The results support the validity of the substrate deprivation therapy and also highlight some limitations.  (+info)

Activation of Src in human breast tumor cell lines: elevated levels of phosphotyrosine phosphatase activity that preferentially recognizes the Src carboxy terminal negative regulatory tyrosine 530. (4/34326)

Elevated levels of Src kinase activity have been reported in a number of human cancers, including colon and breast cancer. We have analysed four human breast tumor cell lines that exhibit high levels of Src kinase activity, and have determined that these cell lines also exhibit a high level of a phosphotyrosine phosphatase activity that recognizes the Src carboxy-terminal P-Tyr530 negative regulatory site. Total Src kinase activity in these cell lines is elevated as much as 30-fold over activity in normal control cells and specific activity is elevated as much as 5.6-fold. When the breast tumor cells were grown in the presence of the tyrosine phosphatase inhibitor vanadate, Src kinase activity was reduced in all four breast tumor cell lines, suggesting that Src was being activated by a phosphatase which could recognize the Tyr530 negative regulatory site. In fractionated cell extracts from the breast tumor cells, we found elevated levels of a membrane associated tyrosine phosphatase activity that preferentially dephosphorylated a Src family carboxy-terminal phosphopeptide containing the regulatory tyrosine 530 site. Src was hypophosphorylated in vivo at tyrosine 530 in at least two of the tumor cell lines, further suggesting that Src was being activated by a phosphatase in these cells. In preliminary immunoprecipitation and antibody depletion experiments, we were unable to correlate the major portion of this phosphatase activity with several known phosphatases.  (+info)

Crystal structure of MHC class II-associated p41 Ii fragment bound to cathepsin L reveals the structural basis for differentiation between cathepsins L and S. (5/34326)

The lysosomal cysteine proteases cathepsins S and L play crucial roles in the degradation of the invariant chain during maturation of MHC class II molecules and antigen processing. The p41 form of the invariant chain includes a fragment which specifically inhibits cathepsin L but not S. The crystal structure of the p41 fragment, a homologue of the thyroglobulin type-1 domains, has been determined at 2.0 A resolution in complex with cathepsin L. The structure of the p41 fragment demonstrates a novel fold, consisting of two subdomains, each stabilized by disulfide bridges. The first subdomain is an alpha-helix-beta-strand arrangement, whereas the second subdomain has a predominantly beta-strand arrangement. The wedge shape and three-loop arrangement of the p41 fragment bound to the active site cleft of cathepsin L are reminiscent of the inhibitory edge of cystatins, thus demonstrating the first example of convergent evolution observed in cysteine protease inhibitors. However, the different fold of the p41 fragment results in additional contacts with the top of the R-domain of the enzymes, which defines the specificity-determining S2 and S1' substrate-binding sites. This enables inhibitors based on the thyroglobulin type-1 domain fold, in contrast to the rather non-selective cystatins, to exhibit specificity for their target enzymes.  (+info)

Substrate specificities of SR proteins in constitutive splicing are determined by their RNA recognition motifs and composite pre-mRNA exonic elements. (6/34326)

We report striking differences in the substrate specificities of two human SR proteins, SF2/ASF and SC35, in constitutive splicing. beta-Globin pre-mRNA (exons 1 and 2) is spliced indiscriminately with either SR protein. Human immunodeficiency virus tat pre-mRNA (exons 2 and 3) and immunoglobulin mu-chain (IgM) pre-mRNA (exons C3 and C4) are preferentially spliced with SF2/ASF and SC35, respectively. Using in vitro splicing with mutated or chimeric derivatives of the tat and IgM pre-mRNAs, we defined specific combinations of segments in the downstream exons, which mediate either positive or negative effects to confer SR protein specificity. A series of recombinant chimeric proteins consisting of domains of SF2/ASF and SC35 in various combinations was used to localize trans-acting domains responsible for substrate specificity. The RS domains of SF2/ASF and SC35 can be exchanged without effect on substrate specificity. The RNA recognition motifs (RRMs) of SF2/ASF are active only in the context of a two-RRM structure, and RRM2 has a dominant role in substrate specificity. In contrast, the single RRM of SC35 can function alone, but its substrate specificity can be influenced by the presence of an additional RRM. The RRMs behave as modules that, when present in different combinations, can have positive, neutral, or negative effects on splicing, depending upon the specific substrate. We conclude that SR protein-specific recognition of specific positive and negative pre-mRNA exonic elements via one or more RRMs is a crucial determinant of the substrate specificity of SR proteins in constitutive splicing.  (+info)

Pseudouridine mapping in the Saccharomyces cerevisiae spliceosomal U small nuclear RNAs (snRNAs) reveals that pseudouridine synthase pus1p exhibits a dual substrate specificity for U2 snRNA and tRNA. (7/34326)

Pseudouridine (Psi) residues were localized in the Saccharomyces cerevisiae spliceosomal U small nuclear RNAs (UsnRNAs) by using the chemical mapping method. In contrast to vertebrate UsnRNAs, S. cerevisiae UsnRNAs contain only a few Psi residues, which are located in segments involved in intermolecular RNA-RNA or RNA-protein interactions. At these positions, UsnRNAs are universally modified. When yeast mutants disrupted for one of the several pseudouridine synthase genes (PUS1, PUS2, PUS3, and PUS4) or depleted in rRNA-pseudouridine synthase Cbf5p were tested for UsnRNA Psi content, only the loss of the Pus1p activity was found to affect Psi formation in spliceosomal UsnRNAs. Indeed, Psi44 formation in U2 snRNA was abolished. By using purified Pus1p enzyme and in vitro-produced U2 snRNA, Pus1p is shown here to catalyze Psi44 formation in the S. cerevisiae U2 snRNA. Thus, Pus1p is the first UsnRNA pseudouridine synthase characterized so far which exhibits a dual substrate specificity, acting on both tRNAs and U2 snRNA. As depletion of rRNA-pseudouridine synthase Cbf5p had no effect on UsnRNA Psi content, formation of Psi residues in S. cerevisiae UsnRNAs is not dependent on the Cbf5p-snoRNA guided mechanism.  (+info)

The human F box protein beta-Trcp associates with the Cul1/Skp1 complex and regulates the stability of beta-catenin. (8/34326)

Ubiquitin-conjugation targets numerous cellular regulators for proteasome-mediated degradation. Thus, the identification of ubiquitin ligases and their physiological substrates is crucially important, especially for those cases in which aberrant levels of regulatory proteins (e.g., beta-catenin, p27) result from a deregulated ubiquitination pathway. In yeast, the proteolysis of several G1 regulators is controlled by ubiquitin ligases (or SCFs) formed by three subunits: Skp1, Cul A (Cdc53), and one of many F-box proteins. Specific F-box proteins (Fbps) recruit different substrates to the SCF. Although many Fbps have been identified in mammals, their specific substrates and the existence of multiple SCFs have not yet been reported. We have found that one human Fbp, beta-Trcp (beta-Transducin repeat containing protein), does indeed form a novel SCF with human Skp1 and Cul1. Consistent with recent reports indicating that Xenopus and Drosophila beta-Trcp homologs act as negative regulators of the Wnt/beta-catenin signaling pathway, we report here that human beta-Trcp interacts with beta-catenin in vivo. Furthermore, beta-catenin is specifically stabilized in vivo by the expression of a dominant negative beta-Trcp. These results indicate that the Cul1/Skp1/beta-Trcp complex forms a ubiquitin ligase that mediates the degradation of beta-catenin.  (+info)

Early Activation of Caspases during T Lymphocyte Stimulation Results in Selective Substrate Cleavage in Nonapoptotic Cells | JEMEarly Activation of Caspases during T Lymphocyte Stimulation Results in Selective Substrate Cleavage in Nonapoptotic Cells | JEM
Results presented in this report show that caspase activation after TCR triggering is a physiological, tightly regulated, and early response that appears to be required for efficient T cell activation. Indeed, the selective processing of caspase-3, -6, -7, and -8 was detected within 24 h after anti-CD3 stimulation of peripheral blood lymphocytes. Caspase processing occurred in various T and B cell subsets, and was found in proliferating and nonapoptotic lymphocytes. Activation of caspases was confirmed through binding of caspase-3-processed forms to a specific substrate, and by showing that a cell-permeable substrate was cleaved in intact, activated lymphocytes. Importantly, activation of the caspase cascade was associated to restricted substrate specificity, with cleavage of PARP and Wee1 being observed while two other substrates, DFF45 and RFC140, remained unaffected. Caspase processing after T cell stimulation correlated with a defective lymphocyte activation in the presence of the caspase ...

Probing Steric and Hydrophobic Effects on Enzyme-Substrate Interactions by Protein Engineering | ScienceProbing Steric and Hydrophobic Effects on Enzyme-Substrate Interactions by Protein Engineering | Science
Steric and hydrophobic effects on substrate specificity were probed by protein engineering of subtilisin. Subtilisin has broad peptidase specificity and contains a large hydrophobic substrate binding cleft. A conserved glycine (Gly166), located at the bottom of the substrate binding left, was replaced by 12 nonionic amino acids by the cassette mutagenesis method. Mutant enzymes showed large changes in specificity toward substrates of increasing size and hydrophobicity. In general, the catalytic efficiency (kcat/Km) toward small hydrophobic substrates was increased (up to 16 times) by hydrophobic substitutions at position 166 in the binding cleft. Exceeding the optimal binding volume of the cleft (∼160 Å3), by enlarging either the substrate side chain or the side chain at position 166, evoked precipitous drops in catalytic efficiency (kcat/Km) (up to 5000 times) as a result of steric hindrance. ...

Protease-substrate interactions are governed by a variety of structural features. Although the substrate sequence specificities of numerous proteases have been established, topological specificities, whereby proteases may be classified based on recognition of distinct three-dimensional structural motifs, have not. The aggrecanase members of the ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) family cleave a variety of proteins but do not seem to possess distinct sequence specificities. In the present study, the topological substrate specificity of ADAMTS-4 (aggrecanase-1) was examined using triple-helical or single-stranded poly(Pro) II helical peptides. Substrate topology modulated the affinity and sequence specificity of ADAMTS-4 with K(m) values indicating a preference for triple-helical structure. In turn, non-catalytic ADAMTS-4 domains were critical for hydrolysis of triple-helical and poly(Pro) II helical substrates. Comparison of ADAMTS-4 with MMP-1 (collagenase 1), MMP

X-converting enzyme (XCE) involved in nervous control of respiration, is a member of the M13 family of zinc peptidases, for which no natural substrate has been identified yet. In contrast, its well characterized homologue endothelin-converting enzyme-1 (ECE-1) showed broad substrate specificity and acts as endopeptidase as well as dipeptidase. To explore the structural differences between XCE and ECE-1, homology model of XCE was built using the complex structure of ECE-1 with phosphoramidon (pdb-id: 3DWB) as template. Phosphoramidon was docked into the binding site of XCE whereas phosphate oxygen of the inhibitor was used as water molecule to design the apo forms of both enzymes. Molecular dynamics simulation of both enzymes was performed to analyze the dynamic nature of their active site residues in the absence and presence of the inhibitor. Homology model of XCE explained the role of non-conserved residues of its S2 subsite. Molecular dynamics (MD) simulations identified the flexible transitions of

UGT8 has been an outlier member of the UGT superfamily since its discovery in 1993 (Schulte and Stoffel, 1993). Initially called ceramide galactosyl-transferase, the gene was identified by purification of the protein conferring ceramide-galactosyl-transferase activity and protein sequencing, followed by screening of a rat brain cDNA library with probes derived from the deduced nucleotide sequence (Schulte and Stoffel, 1993). In common with other UGTs, UGT8 has a molecular mass in the 50-60 kDa range and carries the UGT signature sequence and motifs associated with retention in the endoplasmic reticulum membrane. Until now the substrate specificity of UGT8 has never been broadly investigated. We found that UGT8 had restricted substrate specificity and did not conjugate classic xenobiotic substrates common to most UGT1, 2, and 3 isoforms such as 4-methylumbelliferone and 4-nitrophenol (Uchaipichat et al., 2004), although it did conjugate one of the tested bioflavones (chrysin).

We previously reported that the in vitro inhibitory effects of several OATP1B1 inhibitors showed remarkable substrate-dependence using prototypical substrates, E2G, E1S, and BSP (Izumi et al., 2013). In addition to the prototypical substrates, clinically used OATP1B1 substrate drugs could also serve as in vitro OATP1B1 probe substrates, for which the potential substrate-dependent inhibition has not been comprehensively evaluated. To identify representative in vitro OATP1B1 probe substrates that could mitigate the risk of false-negative DDI prediction, this study investigated the impact of in vitro substrate selection on OATP1B1 inhibition and the subsequent DDI prediction for 12 clinically used OATP1B1 substrate drugs compared with the prototypical probe substrates..

Cytochrome P450 (CYP) enzymes represent a large superfamily that displays extraordinarily diverse substrate specificities. After a concise review about CYPs of the CYP1A subfamily, which plays a crucial role in procarcinogen activation, this paper presents segment-directed mutagenesis. This approach generates a library of random combinatorial mutants limited to a precise region of human CYP1A1, namely amino acids 204-214 in which nine positions differ between CYP1A1 and CYP1A2. The resulting mutants present all combinations possible among these nine positions shifting mutated residues to their CYP1A2 counterpart. The mutants were cloned and expressed in an engineered Saccharomyces cerevisiae strain that has a microsomal oxido-reduction environment optimized for CYPs. This procedure resulted in yeast transformants that express a library of mutant CYP1A1. A subset of transformants were chosen at random, assayed for a typical CYP1A1 activity and the plasmidic DNA of functional clones was rescued and

A technique for forming films of material (12) from a donor substrate (10). The technique has a step of introducing energetic particles (22) through a surface of a donor substrate (10) to a selected depth (20) underneath the surface, where the particles have a relatively high concentration to define donor substrate material (12) above the selected depth. Energy is provided to a selected region of the substrate to cleave a thin film of material from the donor substrate. Particles are introduced again into the donor substrate underneath a fresh surface of the donor substrate. A second thin film of material is then cleaved from the donor substrate.

2020 - Controlling Docks - Teagasc | Agriculture and Food Development Authority2020 - Controlling Docks - Teagasc | Agriculture and Food Development Authority
Controlling Docks:. Before spraying docks, farmers must look at why some fields are worse for docks than others and how docks can be prevented etc. Keeping a thick, dense and leafy sward will reduce or even eliminate docks as grass will out-compete the docks for space, light and nutrients. Topping and grazing tight swards will also help improve the density of regrowth of grass thus reducing dock populations.. When spraying for docks it is essential that you use the correct product, at the correct rate and at the correct time. Always spray when the docks are green, growing and are at the rosette stage. Avoid spraying on windy days etc. There are many different products and ingredients to consider when deciding what sprays to use. Being in contact with farmers over the last few weeks I have heard farmers using an array of different products to control docks, some of these include Dockstar Pro Fore Front T, Pasture Pack, and Hurler. Some of the main active ingredients to look out for when ...

All readers of Zhou et al. and the companion article by Yang et al. will no doubt agree that this work from Yigong Shis group represents a tour de force in applying cryoEM to the structure of the γ-secretase complex with either of two key substrates cross-linked to it. The atomic resolution detailing the juxtaposition of many specific PS1 residues to those of the C83 fragment of APP or to an analogous transmembrane (TM) fragment of Notch elegantly extends certain biochemical studies of presenilin structure-function relationships reported over the last two decades. Some substrate-enzyme interactions previously postulated in biochemical analyses are now firmly established by the structural work. Two examples are the importance of the PS1 transmembrane domain (TMD) 1-2 loop in substrate recognition (Takagi-Niidome et al., 2015) and the pattern of the S1-S2-S3 pockets on the PS1 enzyme that respectively accept large-small-large side chains of APP to effect the tripeptide cleavages (Bolduc et ...

Enzymes - Revision Cards in A Level and IB BiologyEnzymes - Revision Cards in A Level and IB Biology
Enzyme- Enzymes are globular proteins, with a specific tertiary structure, which catalyse metabolic reactions in living organisms.. Enzymes are also known as biological catalysts because they speed up chemical reactions. They have a very specific 3D shape which is determined by their tertiary structure. The active site is the most important part of an enzyme. This is where the enzymes substrate binds. One theory of enzyme action is called the lock and key theory because the enzymes active site and the substrate are complementary in shape and charge.. Intacelluar Enzymes- Enzymes that catalyse reactions inside of cells. e.g Catalase, ATPsynthase, ATPase, DNA helicase, DNA polymerase, RNA polymerase, Lysosome hydrolytic enzymes. Extracellular Enzymes- Enzymes that catalyse reactions outside of cells.e.g digestive enymes. ...

Enzymes, commonly known as biocatalysts, are unique and highly specific globular proteins.. They accelerate chemical reactions without themselves undergoing any apparent change during the process.. They are produced within the cells but are capable of action outside the cells. The word enzyme was first introduced by Kuhne in 1878. Each enzyme usually acts on a single substrate and is said to be highly specific in its action.. According to lock and key hypothesis, the substrate molecules fit into the active sites located on the surface of the enzyme molecules just as one particu-lar key fits into one particular lock.. ...

AU - Jin, P.. AU - Morgan, D. O.. AU - Fisher, R. P.. PY - 2001/1/1. Y1 - 2001/1/1. N2 - Cyclin-dependent kinase 7 (CDK7) is the catalytic subunit of the metazoan CDK-activating kinase (CAK), which activates CDKs, such as CDC2 and CDK2, through phosphorylation of a conserved threonine residue in the T loop. Full activation of CDK7 requires association with a positive regulatory subunit, cyclin H, and phosphorylation of a conserved threonine residue at position 170 in its own T loop. We show that threonine-170 of CDK7 is phosphorylated in vitro by its targets, CDC2 and CDK2, which also phosphorylate serine-164 in the CDK7 T loop, a site that perfectly matches their consensus phosphorylation site. In contrast, neither CDK4 nor CDK7 itself can phosphorylate the CDK7 T loop in vitro. The ability of CDC2 ...

Use:. This mmp substrate can be used to assess activity of enzymes in the MMP family. The peptide sequence was described originally as a biosensor for MT1-MMP or MMP14 in Simultaneous visualization of protumorigenic Src and MT1-MMP activities with fluorescence resonance energy transfer. Ouyang M, et al. Cancer Res. 2010 Mar 15;70(6):2204-12. doi: 10.1158/0008-5472.CAN-09-3698″. It demonstrates reasonably strong activity against MT1-MMP or MMP14 and MMP3, but has the highest activity against MMP9 with specificity constants, kcat/Km (M-1s-1), ranging from approximately 103 to 106. See also our Product Sheets for its substrate specificity profile. This substrate is not processed by ADAM family members. Typically, the peptide is dissolved in DMSO to make a stock solution of about 10mM concentration. When used for in vitro assays, the substrate is often used at about 10uM concentration. Remember to keep the DMSO concentration in the final reaction at 1% or below, to avoid DMSO effects on the ...

Background: Our understanding of how fungi evolved to develop a variety of ecological niches, is limited but of fundamental biological importance. Specifically, the evolution of enzymes affects how well species can adapt to new environmental conditions. Feruloyl esterases (FAEs) are enzymes able to hydrolyze the ester bonds linking ferulic acid to plant cell wall polysaccharides. The diversity of substrate specificities found in the FAE family shows that this family is old enough to have experienced the emergence and loss of many activities. Methodology/Principal Findings: In this study we evaluate the relative activity of FAEs against a variety of model substrates as a novel predictive tool for Ascomycota taxonomic classification. Our approach consists of two analytical steps; (1) an initial unsupervised analysis to cluster the FAEs substrate specificity data which were generated by cultivation of 34 Ascomycota strains and then an analysis of the produced enzyme cocktail against 10 substituted

AmpC BER is an extended substrate spectrum class C beta-lactamase with a two-amino-acid insertion in the R2 loop compared with AmpC EC2. The crystal structures of AmpC BER (S64A mutant) and AmpC EC2 were determined. Structural comparison of the two proteins revealed that the insertion increases the conformational flexibility of the R2 loop. Two citrate molecules originating from the crystallization solution were observed in the active site of the S64A mutant. One citrate molecule makes extensive interactions with active-site residues that are highly conserved among class C beta-lactamases, whereas the other one is weakly bound. Based on this structural observation, it is demonstrated that citrate, a primary metabolite that is widely used as a food additive, is a competitive inhibitor of two class C beta-lactamases (AmpC BER and CMY-10). Consequently, the data indicate enhancement of the flexibility of the R2 loop as an operative strategy for molecular evolution of extended-spectrum class C ...

Vanillyl alcohol oxidase (VAO) and eugenol oxidase (EUGO) are flavin-dependent enzymes that catalyse the oxidation of para-substituted phenols. This makes them potentially interesting biocatalysts for the conversion of lignin-derived aromatic monomers to value-added compounds. To facilitate their biocatalytic exploitation, it is important to develop methods by which variants of the enzymes can be rapidly screened for increased activity towards substrates of interest. Here, we present the development of a screening assay for the substrate specificity of para-phenol oxidases based on the detection of hydrogen peroxide using the ferric-xylenol orange complex method. The assay was used to screen the activity of VAO and EUGO towards a set of twenty-four potential substrates. This led to the identification of 4-cyclopentylphenol as a new substrate of VAO and EUGO and 4-cyclohexylphenol as a new substrate of VAO. Screening of a small library of VAO and EUGO active-site variants for alterations in their

Phytaspase - WikipediaPhytaspase - Wikipedia
Phytaspase is a member of the plant subtilisin-like protease family, and is commonly distinguished from the other members by its unusual and extremely high specificity towards its substrates, which resembles that of the animal caspases. Similarly to the animal caspases, the phytaspase is a cell death promoting protease. The name phytaspase comes from phyto- (lat. for plant) and -aspase (aspartate-directed protease), similarly to caspases. The phytaspase displays a strict substrate specificity, which resembles that of the animal caspase-3. It recognizes a tetrapetide motive within a target protein and introduces a peptide bond break following an aspartate residue, which is crucial for the hydrolysis. Theoretical speculations, based on a 3D model predictions have been made, pointing to the histidine 331 of the phytaspase peptide chain, that might interact with the Asp in the target peptide and thereby guide the recognition. The phytaspase displays a structure, common to the subtilisin-like ...

Structural Basis of Caspase-3 Substrate Specificity Revealed by Crysta by Bin FangStructural Basis of Caspase-3 Substrate Specificity Revealed by Crysta by Bin Fang
Caspase-3 is a cysteine protease that hydrolyzes diverse intracellular proteins during programmed cell death (known as apoptosis). It has been a popular target for drug design against abnormal cell death for more than a decade. No approved caspase based drug, however, is available so far. Therefore, structural insights about the substrate recognition of caspase-3 are needed for the future development of caspase-3 based inhibitors and drugs. In this study, crystal structures of recombinant caspase-3 in complex with seven substrate analog inhibitors, including acetyl (Ac)-DEVD-aldehyde (Cho), Ac-DMQD-Cho, Ac-IEPD-Cho, Ac-YVAD-Cho, Ac-WEHD-Cho, Ac-VDVAD-Cho, and tert-butoxycarbonyl (Boc)-D-fluoromethylketone (Fmk), have been analyzed in combination with enzyme kinetic data and computational models. Seven crystal structures were determined at resolutions of 1.7-2.6Å. The binding conformation of each inhibitor residue at P1-P4 position was analyzed.

We are interested in the mechanistic and molecular relationships between catalytic activity, conformational changes and microenvironment of ABC transporters. P-glycoprotein (ABCB1, Pgp) is in the focus of our interest; we have currently extended our work to ABCG2 (BCRP) and plan to do similar studies on MRP1 (ABCC1). The members of the ABC superfamily of membrane transporters are involved in the regulation of the uptake into and distribution within our body of physiological substrates as well as various xenobiotics, drugs. Due to their wide substrate spectrum, a consequence of their preference for lipophylic compounds, they also play a critical role in the multidrug resistance phenomenon severely limiting therapeutical success in cancer. Our ambition is to understand the molecular details of their catalytic cycle and the intimate molecular interactions with their microenvironment, as well as to apply the knowledge obtained at the cell/molecule level in the context of the whole organism, in ...

The primary specificity residue of a substrate or an inhibitor, called the P1 residue, is responsible for the proper recognition by the cognate enzyme. This residue enters the S1 pocket of the enzyme and establishes contacts (up to 50%) inside the proteinase substrate cavity, strongly affecting its specificity. To analyze the influence on bovine α-chymotrypsin substrate activity, aromatic non-proteinogenic amino acid residues in position P1 with the sequence Ac-Phe-Ala-Thr-XAnb 5,2-NH2 were introduced: L-pyridyl alanine (Pal), 4-nitrophenylalanine - Phe(p-NO2), 4-aminophenylalanine - Phe(p- NH2), 4-carboxyphenylalanine Phe(p-COOH), 4-guanidine phenylalanine - Phe(p-guanidine), 4-methyloxycarbonylphenylalanine - Phe(p-COOMe), 4-cyanophenylalanine - Phe(p-CN), Phe, Tyr. The effect of the additional substituent at the phenyl ring of the Phe residue was investigated. All peptides contained an amide of 5-amino-2-nitrobenzoic acid, which served as a chromophore.

Identification of substrates for Ser/Thr kinases using residue-based statistical pair potentials : Bioinformatics - oiIdentification of substrates for Ser/Thr kinases using residue-based statistical pair potentials : Bioinformatics - oi
Motivation:In silico methods are being widely used for identifying substrates for various kinases and deciphering cell signaling networks. However, most of the available phosphorylation site prediction methods use motifs or profiles derived from a known data set of kinase substrates and hence, their applicability is limited to only those kinase families for which experimental substrate data is available. This prompted us to develop a novel multi-scale structure-based approach which does not require training using experimental substrate data.. Results:In this work, for the first time, we have used residue-based statistical pair potentials for scoring the binding energy of various substrate peptides in complex with kinases. Extensive benchmarking on Phospho.ELM data set indicate that our method outperforms other structure-based methods and has a prediction accuracy comparable to available sequence-based methods. We also demonstrate that the rank of the true substrate can be further improved, if ...

ETS-targeted therapy: can it substitute for MEK inhibitors? | Clinical and Translational Medicine | Full TextETS-targeted therapy: can it substitute for MEK inhibitors? | Clinical and Translational Medicine | Full Text
The RAS/MAPK pathway has been intensively studied [1-4], with constitutive activation of ERK1 and ERK2 found frequently in human cancer cells from a variety of tissues (e.g., lung, pancreas, colon, ovary, kidney, skin, and thyroid) [13]. Amplification, overexpression, or mutations in RTKs and genetic alterations in upstream components of the MAPK pathway, including KRAS, NRAS, HRAS, CRAF, BRAF, MEK1, and MEK2, alter cell signaling in tumors. In clinical practice and clinical trials, small molecules targeting RTKs or components in the MAPK cascade are used to treat cancer [1, 3, 4]. MEK1 and MEK2 are ideal targets; not only do they play a key role in tumor development and progression [3, 4], they have narrow substrate specificities and distinctive structural characteristics.. MEK activation through the MAPK signaling cascade is necessary for mammalian cell transformation, and constitutively active MEK mutants promote transformation of fibroblast cells [14, 15]. Furthermore, MEK inhibitors inhibit ...

Chaetoviridins constitute a large family of structurally related secondary metabolites isolated from Chaetomium fungi. To elucidate the biosynthesis pathway and understand how the chemical diversity of chaetoviridins is generated, gene deletion and in vitro characterization of the four post-PKS modifications enzymes were undertaken. CazL and CazP were identified to have substrate promiscuity that facilitates the formation of nonchlorinated analogues. In addition, enzymatic oxidation and reduction combined with spontaneous dehydration and lactonization of the intermediates further expand the chemical diversity ...

Energetics & EnzymesEnergetics & Enzymes
Thus, when a great deal of substrate is altered by an enzyme every minute, the reaction is said to be proceeding at a rapid rate.. In enzyme reaction rates, the rate depends on the CONCENTRATION of the enzyme and the CONCENTRATION of the substrate (CONCENTRATION rather than AMOUNT). Concentration refers to amount in a given volume of solution. As previously mentioned, it has been calculated that enzyme mediated reactions occur 1 x 109 times faster than the same reactions without enzymes.. In most enzyme reactions, enzyme concentration is small compared to the substrate concentration. Therefore, the rate of the reaction becomes proportional to the concentration of the enzyme. If the enzyme concentration is doubled, the reaction rate is doubled. At low substrate concentrations, the rate of the reaction is proportional to the substrate concentration, but at higher substrate concentrations the reaction rate is independent of substrate concentration. That is, further increase in the amount of ...

Abstract Primary cilia are organelles necessary for proper implementation of developmental and homeostasis processes. To initiate their assembly, coordinated actions of multiple proteins are needed. Tau tubulin kinase 2 (TTBK2) is a key player in the cilium assembly pathway, controlling final step of cilia initiation. The function of TTBK2 in ciliogenesisis critically dependent on its kinase activity, however, precise mechanism of action of this kinase is so far incompletely understood, in part due to very limited information about its relevant substrates. In this study we identify CEP83, CEP89, CCDC92, Rabin8 and DVL3 as substrates of TTBK2 kinase activity. Further, we characterise a set of phosphosites of the newly identified substrates and CEP164, induced by TTBK2 in vitro and in vivo and show that TTBK2 preferentially phosphorylates examined substrates at intrinsically disordered regions (IDRs). Intriguingly, we further show that identified TTBK2 phosphosites and consensus sequence ...

At the atomic scale, we are interested in providing detailed three-dimensional information about the nature of complex metallocofactors to help understand how protein environment modulates reactivity. At the protein scale, we are interested in seeing how enzymes are constructed to control substrate access and specificity, and how they prevent loss of reactive intermediates or damage to expensive cofactors. At the largest scale, that of protein complexes, we want to know how proteins interact and how those interactions explain the observed behavior. Protein complexes are often large, have multiple distinct states, and can have large inter- and intrasubunit motions; therefore a single snapshot usually does not tell the entire story.. ...
