The amino acid sequence of Neurospora NADP-specific glutamate dehydrogenase. Peptides from digestion with a staphylococcal proteinase. (1/6114)

The extracellular proteinase of Staphylococcus aureus strain V8 was used to digest the NADP-specific glutamate dehydrogenase of Neurospora crassa. Of 35 non-overlapping peptides expected from the glutamate content of the polypeptide chain, 29 were isolated and substantially sequenced. The sequences obtained were valuable in providing overlaps for the alignment of about two-thirds of the sequences found in tryptic peptides [Wootton, J. C., Taylor, J, G., Jackson, A. A., Chambers, G. K. & Fincham, J. R. S. (1975) Biochem. J. 149, 739-748]. The blocked N-terminal peptide of the protein was isolated. This peptide was sequenced by mass spectrometry, and found to have N-terminal N-acetylserine by Howard R. Morris and Anne Dell, whose results are presented as an Appendix to the main paper. The staphylococcal proteinase showed very high specificity for glutamyl bonds in the NH4HCO3 buffer used. Partial splits of two aspartyl bonds, both Asp-Ile, were probably attributable to the proteinase. No cleavage of glutaminyl or S-carboxymethylcysteinyl bonds was found. Additional experimental detail has been deposited as Supplementary Publication SUP 50053 (5 pages) with the British Library (Lending Division), Boston Spa, Wetherby, W. Yorkshire LS23 7BQ, U.K, from whom copies may be obtained under the terms given in Biochem. J. (1975) 1458 5.  (+info)

Purification of gibberellic acid-induced lysosomes from wheat aleurone cells. (2/6114)

Using isopycnic density gradient centrifugation, lysosomes were concentrated in a single region of a sucrose-Ficoll gradient (p = 1-10 g cm-3), well separated from most other cell organelles. Gibberellic acid-induced lysosomes were found to be rich in alpha-amylase and protease but not ribonuclease. The lysosomal band also contained a majority of the NADH2-cytochrome c reductase, a marker enzyme for endoplasmic reticulum, found in the gradient. Examination of electron micrographs revealed that a purified band of lyosomes contained at least 3 vesicle types, ranging in size from 0-1 to 0-5 mum. The significance of these findings to proposed mechanisms of action of gibberellic acid is discussed.  (+info)

5'-Nucleotidase activity of mouse peritoneal macrophages. I. Synthesis and degradation in resident and inflammatory populations. (3/6114)

Mouse resident peritoneal macrophages display sufficient 5'-nucleotidase activity to hydrolyze 58 nm AMP/min per cell protein. This activity increases approximately 163 nm AMP/min per mg after 72 h in culture. The enzyme is renewed in unstimulated cells with a half-time of 13.9 h. The activity is not reduced by treatment of intact cells with a variety of proteolytic enzymes, including trypsin, pronase, urokinase, and plasmin. Cells obtained from an inflammatory exudate have diminished or absent levels of enzyme activity. Endotoxin-elicited cells display enzyme activitiy of 20.9 nm AMP/min per mg, while thioglycollate-stimulated macrophages have no detectable activity. The reduced level of activity in endotoxin-stimulated cells is due to their elevated rate of enzyme degradation, with a half-time of 6.9 h. Their rate of enzyme synthesis is essentially normal. No evidence for latent enzyme activity could be obtained in thioglycollate-stimulated cells, nor do these cells produce any inhibition of normal cell enzyme activity. Serum deprivation reduces the enzyme activity of resident cells to about 45% of control activity. These conditions do not significantly affect the rate of enzyme synthesis, but again are explainable by an increase in the rate of enzyme degradation. Pinocytic rate is elevated in endotoxin-stimulated cells which show a more rapid rate of enzyme degradation than unstimulated cells do. However, in serum-free conditions, the rate of enzyme degradation is doubled with no change in the pinocytic rate of the cells.  (+info)

Genome-linked protein associated with the 5' termini of bacteriophage phi29 DNA. (4/6114)

A DNA-protein complex was isolated from Bacillus subtilis bacteriophage phi29 by sucrose gradient sedimentation or gel filtration in the presence of agents known to break noncovalent bonds. A 28,000-dalton protein was released from this complex by subsequent hydrolysis of the DNA. The DNA-protein complex was examined for its susceptibility to enzymes which act upon the 5' and 3' termini of DNA molecules. It was susceptible to exonucleolytic degradation from the 3' termini by exonuclease III but not from the 5' termini by lambda exonuclease. Attempts to label radioactively the 5' termini by phosphorylation with T4 polynucleotide kinase were unsuccessful despite prior treatment with alkaline phosphatase or phosphatase treatment of denatured DNA. Removal of the majority of the bound protein by proteolytic digestion did not increase susceptibility. These results suggest that the linked protein is covalently attached to the 5' termini of phi29 DNA.  (+info)

Prophenoloxidase-activating enzyme of the silkworm, Bombyx mori. Purification, characterization, and cDNA cloning. (5/6114)

Prophenoloxidase-activating enzyme (PPAE) was purified to homogeneity as judged by SDS-polyacrylamide gel electrophoresis from larval cuticles of the silkworm, Bombyx mori. The purified PPAE preparation was shown to be a mixture of the isozymes of PPAE (PPAE-I and PPAE-II), which were eluted at different retention times in reversed-phase high performance liquid chromatography. PPAE-I and PPAE-II seemed to be post translationally modified isozymes and/or allelic variants. Both PPAE isozymes were proteins composed of two polypeptides (heavy and light chains) that are linked by disulfide linkage(s) and glycosylated serine proteases. The results of cDNA cloning, peptide mapping, and amino acid sequencing of PPAE revealed that PPAE is synthesized as prepro-PPAE with 441 amino acid residues and is activated from pro-PPAE by cleavage of a peptide bond between Lys152 and Ile153. The homology search showed 36.9% identity of PPAE to easter, which is a serine protease involved in dorso-ventral pattern formation in the Drosophila embryo, and indicated the presence of two consecutive clip-like domains in the light chain. A single copy of the PPAE gene was suggested to be present in the silkworm genome. In the fifth instar larvae, PPAE transcripts were detected in the integument, hemocytes, and salivary glands but not in the fat body or mid gut. A polypeptide cross-reactive to mono-specific anti-PPAE/IgG was transiently detected in the extract of eggs between 1 and 3 h after they were laid.  (+info)

Direct evidence of Na+/Ca2+ exchange in squid rhabdomeric membranes. (6/6114)

Na+/Ca2+ exchange has been investigated in squid (Loligo pealei) rhabdomeric membranes. Ca2+-containing vesicles have been prepared from purified rhabdomeric membranes by extrusion through polycarbonate filters of 1-micrometer pore size. After removal of external Ca2+, up to 90% of the entrapped Ca2+ could be specifically released by the addition of Na+; this finding indicates that most of the vesicles contained Na+/Ca2+ exchanger. The Na+-induced Ca2+ efflux had a half-maximum value (K1/2) of approximately 44 mM and a Hill coefficient of approximately 1.7. The maximal Na+-induced Ca2+ efflux was approximately 0.6 nmol Ca2+. s-1. mg protein-1. Similar Na+-induced Ca2+ effluxes were measured if K+ was replaced with Li+ or Cs+. Vesicles loaded with Ca2+ by Na+/Ca2+ exchange also released this Ca2+ by Na+/Ca2+ exchange, suggesting that Na+/Ca2+ exchange operated in both forward and reverse modes. Limited proteolysis by trypsin resulted in a rate of Ca2+ efflux enhanced by approximately fivefold when efflux was activated with 95 mM NaCl. For vesicles subjected to limited proteolysis by trypsin, Na+/Ca2+ exchange was characterized by a K1/2 of approximately 25 mM and a Hill coefficient of 1.6. For these vesicles, the maximal Na+-induced Ca2+ efflux was about twice as great as in control vesicles. We conclude that Na+/Ca2+ exchange proteins localized in rhabdomeric membranes mediate Ca2+ extrusion in squid photoreceptors.  (+info)

Identification of kallidin degrading enzymes in the isolated perfused rat heart. (8/6114)

Kallidin (KD) is an important vasoactive kinin whose physiological effects are strongly dependent on its degradation through local kininases. In the present study, we examined the spectrum of these enzymes and their contribution to KD degradation in isolated perfused rat hearts. By inhibiting angiotensin-converting enzyme (ACE), aminopeptidase M (APM) and neutral endopeptidase (NEP) with ramiprilat (0.25 microM), amastatin (40 microM) and phosphoramidon (1 microM), respectively, relative kininase activities were obtained. APM (44%) and ACE (35%) are the main KD degrading enzymes in rat heart; NEP (7%) plays a minor role. A participation of carboxypeptidase N (CPN) could not be found.  (+info)

PURPOSE The corneal destruction resulting from P. aeruginosa keratitis is thought to be due, in part, to the actions of host and bacterial proteases on corneal tissue. The intent of the current study was to compare host and bacterial protease expression in the ocular tissues of mice that have been shown to be susceptible to corneal infection with mice that have been protected from such infection as a result of prior immunization. METHODS Supernatants of infected corneal homogenates from naive mice or from mice immunized as a result of prior corneal infection or that had been immunized against bacterial protease were analyzed by gelatin zymography for the presence of host gelatinases and bacterial proteases at various times after infection. In addition, studies were carried out to examine the effect of immunization with bacterial protease on numbers of ocular bacteria. RESULTS Mice that were protected against the tissue destruction during infection were found to have reduced proteolytic activity in
Probable protease subunit of the COP9 signalosome complex (CSN), a complex involved in various cellular and developmental processes such as photomorphogenesis and auxin and jasmonate responses. The CSN complex is an essential regulator of the ubiquitin (Ubl) conjugation pathway by mediating the deneddylation of the cullin subunits of the SCF-type E3 ligase complexes, leading to decrease the Ubl ligase activity of SCF. In the complex, it probably acts as the catalytic center that mediates the cleavage of Nedd8 from cullins. It however has no metalloprotease activity by itself and requires the other subunits of the CSN complex (By similarity). The CSN complex is involved in repression of photomorphogenesis in darkness by regulating the activity of COP1-containing Ubl ligase complexes. The complex is also required for degradation of PSIAA6 by regulating the activity of the Ubl ligase SCF-TIR complex. Not involved in CSNs deneddylation/derubylation activity (PubMed:15486099, PubMed:17307927). Essential for

Targeting recombinant proteins toward the extracellular space offers several advantages in terms of protein folding and purification, but degradation events are observed, due to endogenous peptidases. This paper focuses on the analysis of extracellular proteolytic activities in two production systems: cell cultures and root-secretion (rhizosecretion), in Arabidopsis thaliana and Nicotiana tabacum. Proteolytic activities of extracellular proteomes ...
This gene encodes a protein involved in processing the signal peptide sequences used to direct mitochondrial proteins to the mitochondria. The encoded protein resides in the mitochondria and is one of the necessary proteins for the catalytic activity of the mitochondrial inner membrane peptidase (IMP) complex. Two variants that encode the same protein have been described for this gene. [provided by RefSeq, Sep 2011 ...
Catalyzes the removal of transit peptides required for the targeting of proteins from the mitochondrial matrix, across the inner membrane, into the inter-membrane space. Known to process the nuclear encoded protein DIABLO.
It is clear that intramembrane proteolysis regulates many biological processes. As with other intramembrane proteases such as γ‐secretase/presenilin and SPP (Martoglio and Golde, 2003; Selkoe and Schenk, 2003), rhomboids may turn out to be useful therapeutic targets (Opitz et al, 2002; Urban and Freeman, 2003). The lack of an in vitro assay for rhomboid activity has been a limiting factor in the biochemical analysis of their proteolytic mechanisms. We have now demonstrated rhomboid activity both in detergent‐solubilised membrane extracts and in a highly purified fraction. These two versions of the in vitro assay have different utilities. The activity of multiple rhomboids can be rapidly determined in TX100 membrane extracts; and in purified fractions, precise quantification of relative activities can be measured. Here we have exploited both approaches to show that diverse rhomboids have differential activities on three model substrates, and to compare the activities of a number of purified ...

TY - JOUR. T1 - The endothelial glycocalyx as a barrier to leukocyte adhesion and its mediation by extracellular proteases. AU - Lipowsky, Herbert H.. PY - 2012/4/1. Y1 - 2012/4/1. N2 - The endothelial cell (EC) surface is coated with a layer of polysaccharides linked to membrane-bound and trans-membrane proteoglycans that comprise the glycocalyx, which is augmented by adsorbed proteins derived from the blood stream. This surface layer has been shown to affect hemodynamics in small blood vessels of the microcirculation, the resistance to flow, and leukocyte (WBC) to EC adhesion. Parallel studies of WBC-EC adhesion in response to chemo-attractants and cytokines, and shedding of constituents of the glycocalyx, have suggested a role for activation of extracellular proteases in mediating the dynamics of WBC adhesion in response to inflammatory and ischemic stimuli. Likely candidates among the many proteases present are the matrix metalloproteases (MMPs). Inhibition of MMP activation with ...
We report a functional protease assay in which liquid crystals (LCs) are used as signal reporters to transduce the test results into optical signals. In this assay, an oligopeptide substrate (CLSELDDRADALQAGASQFESSAAKLKRKYWWKNLK) is used as a probe. This oligopeptide can be cleaved by α-chymotrypsin at multiple locations and become smaller fragments after the cleavage. When the original oligopeptide is immobilized on a solid surface, its long flexible oligopeptide chain is able to influence the orientation of a thin layer of LC supported on the surface, as is evident as a bright spot on the surface. In contrast, when the shorter oligopeptide fragments are immobilized on the same surface, their shorter, less flexible chains cannot disrupt the orientation of LC, and a dark spot is observed. On the basis of the dark or bright signal from LC, α-chymotrypsin in buffer solution or complex media such as chicken broth can be detected by using the naked eye. However, when the incubation time is 3. h, ...

EC 3.2 Glycosylases. Glycosylases are classified under hydrolases, although some of them can also transfer glycosyl residues to oligosaccharides, polysaccharides and other alcoholic acceptors. The glycosylases are subdivided into those hydrolysing O- or S-glycosyl compounds (EC 3.2.1 and EC 3.2.3), i.e. glycosides, and those hydrolysing N-glycosyl compounds (EC 3.2.2). Accepted names for enzymes acting on D-sugars or their derivatives do not contain D, unless ambiguity would result from the common existance of the corresponding L-sugar.. EC 3.3 Acting on ether bonds. To this small subclass belong enzymes acting on ether bonds. It is subdivided into those hydrolysing on thioether and trialkylsulfonium compounds (EC 3.3.1) and those acting on ethers (EC 3.3.2).. EC 3.4 Acting on Peptide Bonds (Peptidases) It is recommended that the term peptidase be used as synonymous with peptide hydrolase for any enzyme that hydrolyses peptide bonds. Peptidases are recommended to be further divided into ...

Extracellular matrix (ECM)1 serves as the immediate microenvironment for interactions with the cell surface, besides providing the structural support for all tissues. The ECM is not static. Rather, it is dynamic in nature with a continuous turnover of its protein constituents and growth factor pools. A major determinant of ECM turnover and integrity is the extracellular proteolytic balance between secreted matrix metalloproteinases (MMPs) and their biological inhibitors (TIMPs) (for reviews see Matrisian 1992; Denhardt et al. 1993; Mignatti and Rifkin 1993). The function of extracellular proteolysis extends beyond ECM degradation to the processing of cell surface receptors and ligands and release of protein-bound growth factors (for review see Werb 1997). Therefore, it is conceivable that extracellular proteolytic activity within the cellular microenvironment can directly impact cell proliferation. Despite transgenic studies showing that cellular proliferation is altered by ectopic expression of ...
This thesis presents a study of lipolytic and proteolytic enzymatic processes during rapid-ripening of herring filets. The aim of this study is to investigate the enzymatic activity in such a ripening process, and how the enzymes affect the biochemical parameters through such a process. In particular, proteolytic enzyme activity, its effect on the changes in amino acid profiles depending on different experimental parameters and the lipolytic enzyme activity will be analyzed. This is done by setting up a herring ripening experiment with samples taken in regular intervals through a time series, and investigating how the enzymatic activity profiles, both specific and general, change over time. In addition, to investigate the effect of proteolytic enzyme activity the free amino acid composition is analyzed throughout the time series. Herring caught in the Trondheim Fjord were gutted and cut into filets before being added to a sugar-salt brine with low salt concentration. To enhance the ripening ...
One contributing factor to the increased ability of more stable antigens to elicit immune responses is that the restricted susceptibility to lysosomal proteolysis favored the production of peptide-MHC class II complexes by DCs, at least in vitro (Fig. 2 E and Fig. 4 D). In addition, and just as important in an in vivo setting, we found that the increased stability to lysosomal proteolysis also favored the retention of antigens captured by DCs to lymphoid organs. 16 h after a single intradermal injection, the stable forms of RNase (Alexa 488-RNase-A) could be detected in CD11c+ DCs in the draining lymph nodes (Fig. 1 D). In contrast, the rapidly degraded form (Alexa 647-RNase-S) was barely detectable under the same conditions (Fig. 1 D). Combined with the fact that differential immunogenicity was observed by adoptively transferring DCs containing either RNase-A or RNase-S (Fig. 2 D), these results strongly suggest that at least one effect of decreased susceptibility to proteolysis is to ...
Half a century ago thalidomide caused one of the biggest pharmaceutical tragedies known by now. It was widely prescribed to pregnant women as a sedative, but displayed teratogenic properties, causing limb malformations and other developmental defects in more than 10,000 babies worldwide. Nevertheless, thalidomide and its derivatives are used nowadays in treatment of leprosy and multiple myeloma. The protein cereblon was identified as a primary target of thalidomide in the cell. As a substrate receptor, cereblon (CRBN) is linked via the damaged DNA binding protein 1 (DDB1) and cullin 4A to the E3 ubiquitin ligase machinery. The drug binds to the C-terminal region of cereblon, also referred to as CULT domain (cereblon domain of unknown activity, binding cellular ligands and thalidomide). This domain represents the most conserved part of cereblon and is also found solely in single-domain proteins in bacteria and, as a secreted form, in eukaryotes. Based on its ligand binding properties, its high ...
The prolyl oligopeptidase family, which is a group of serine peptidases, can hydrolyze peptides smaller than 30 residues. The prolyl oligopeptidase family in plants includes four members, which are prolyl oligopeptidase (POP, EC3.4.21.26), dipeptidyl peptidase IV (DPPIV, EC3.4.14.5), oligopeptidase B (OPB, EC3.4.21.83), and acylaminoacyl peptidase (ACPH, EC3.4.19.1). POP is found in human and rat, and plays important roles in multiple biological processes, such as protein secretion, maturation and degradation of peptide hormones, and neuropathies, signal transduction and memory and learning. However, the function of POP is unclear in plants. In order to study POP function in plants, we cloned the cDNA of the OsPOP5 gene from rice by nested-PCR. Sequence analysis showed that the cDNA encodes a protein of 596 amino acid residues with Mw ≈ 67.29 kD. In order to analyze the protein function under different abiotic stresses, OsPOP5 was expressed in Escherichia coli. OsPOP5 protein enhanced the

Cereblon (CRBN) is encoded by a candidate gene for autosomal recessive nonsyndromic intellectual disability (ID). The nonsense mutation, R419X, causes deletion of 24 amino acids at the C-terminus of CRBN, leading to mild ID. Although abnormal CRBN function may be associated with ID disease onset, its cellular mechanism is still unclear. Here, we examine the role of CRBN in aggresome formation and cytoprotection. In the presence of a proteasome inhibitor, exogenous CRBN formed perinuclear inclusions and co-localized with aggresome markers. Endogenous CRBN also formed perinuclear inclusions under the same condition. Treatment with a microtubule destabilizer or an inhibitor of the E3 ubiquitin ligase activity of CRBN blocked formation of CRBN inclusions. Biochemical analysis showed CRBN containing inclusions were high-molecular weight, ubiquitin-positive. CRBN overexpression in cultured cells suppressed cell death induced by proteasome inhibitor. Furthermore, knockdown of endogenous CRBN in ...

Membrane-bound serine proteases play essential assignments in different natural procedures. the Tyr deletion is in charge of the HAI-2 lack of function. Our useful assay allowed us to recognize membrane-bound serine proteases as mobile focus on for inhibition by HAI-2 outrageous type and mutants, also to better define the function from the Tyr in the next Kunitz domains in the inhibitory activity of HAI-2. Launch Membrane-bound or membrane-anchored serine proteases possess lately emerged being a subfamily of 20 serine proteases that talk about a conserved catalytic domains and a transmembrane domains [1]. They screen different pathophysiological and physiological assignments such as for example assignments in epidermis and intestinal hurdle integrity [2]C[5], handling of atrial natriuretic peptide [6], iron homeostasis [7]C[9], trophoblastic advancement [10], hearing [11], ion and [12] homeostasis [13], [14]. Even more elusive, however, will be the identity as well as the assignments of their ...
Sedolisins (serine-carboxyl peptidases) are proteolytic enzymes whose fold resembles that of subtilisin; however, they are considerably larger, with the mature catalytic domains containing approximately 375 amino acids. The defining features of these enzymes are a unique catalytic triad, Ser-Glu-Asp, as well as the presence of an aspartic acid residue in the oxyanion hole. High-resolution crystal structures have now been solved for sedolisin from Pseudomonas sp. 101, as well as for kumamolisin from a thermophilic bacterium, Bacillus novo sp. MN-32. The availability of these crystal structures enabled us to model the structure of mammalian CLN2, an enzyme which, when mutated in humans, leads to a fatal neurodegenerative disease. This review compares the structural and enzymatic properties of this newly defined MEROPS family of peptidases, S53, and introduces their new nomenclature ...

Proteolytic Enzymes are best taken with a full glass of water on an empty stomach at least 45 minutes before any meal and up to two hours after a meal. They should be Enteric-Coated to pass through the stomach where in the small intestine they dissolve because of PH change. There they become digestive enzymes to help us digest our food and convert proteins into free amino acids, which are easily absorbed by the cells of the intestinal wall. Important note: It is believed if too much processed and overcooked foods/meats are eaten too fast, the pancreas which naturally secretes our enzymes can become overburdened with the digestive enzyme demands. This then creates a situation allowing toxins into the body thereby stressing the immune system and providing an opportunity for Cancer. As the Supplemental Proteolytic Enzymes then enter the circulatory system they are called systemic enzymes. There are important precautions before taking Proteolytic Enzymes to consider. They are a known blood thinner. ...

It is now well known that proteases are found everywhere, in viruses and bacteria as well as in all human, animal and plant cells, and play a role in a variety of biological functions ranging from digestion, fertilization, development to senescence and death. Under physiological conditions the ability of proteases is regulated by endogenous inhibitors. However, when the activity of proteases is not regulated appropriately, disease processes can result, as seen in Alzheimers disease, cancer metastasis and tumor progression, inflammation and atherosclerosis. Thus it is evident that there is an absolute need for a tighter control of proteolytic activities in different cells and tissues. Aimed at graduate students and researchers with an interest in cellular proteolytic events, Role of Proteases in Cellular Dysfunctions is the second book on Proteases in this series. The book consists of three parts in specified topics based on current literatures for a better understanding for the readers with ...
Optimized DNA sequence encoding peptidase domain of Human Endothelial lipase(SER21-PRO500) including a C-terminal His tag was expressed in HEK293 cells.
Proteases, also known as peptidases or proteolytic enzymes, consists of a large number of enzymes catalyzing the hydrolysis of peptide bonds and subsequently resulting in the degradation of protein substrates into amino acids. Proteases are involved in a wide range of human diseases, including cancer, neurodegenerative disorders, inflammatory diseases and cardiovascular diseases. Thus numerous proteases inhibitors (small molecules and proteins) have been identified to block activity of proteases. Proteases inhibitors can be classified into different types based on the class of proteases they inhibit through two general mechanisms, irreversible trapping reactions and reversible tight-binding reactions. Proteases inhibitors have been used as diagnostic or therapeutic agents for the treatment of proteases-related diseases.. ...
