Hairpin-shaped DNA duplexes with disulfide bonds in sugar-phosphate backbone as potential DNA reagents for crosslinking with proteins. (1/267)

Convenient approaches were described to incorporate -OP(=O)O(-)-SS-O(-)(O=)PO- bridges in hairpin-shaped DNA duplexes instead of regular phosphodiester linkages: (i) H2O2- or 2,2'-dipyridyldisulfide-mediated coupling of 3'- and 5'-thiophosphorylated oligonucleotides on complementary template and (ii) more selective template-guided autoligation of a preactivated oligonucleotide derivative with an oligomer carrying a terminal thiophosphoryl group. Dithiothreitol was found to cleave completely modified internucleotide linkage releasing starting oligonucleotides. The presence of complementary template as an intrinsic element of the molecule protects the hairpin DNA analog from spontaneous exchange of disulfide-linked oligomer fragments and makes it a good candidate for auto-crosslinking with cysteine-containing proteins.  (+info)

The effect of carboxyl group modification on the chromophore regeneration of archaeopsin-1 and bacterioopsin. (2/267)

Carboxyl group modification with DCCD and NCD-4 was employed to investigate the chemical environment of the side chains of archaeopsin-1 (aO-1) and bacterioopsin (bO). Some differences were observed between aO-1 and bO. Although DCCD or NCD-4 did not modify aO-1 in bleached membrane, they modified bO in bleached membrane and in mixed DMPC/CHAPS/SDS micelles at neutral pH, thereby affecting the opsin shift and the photocycle of the regenerated chromophore. On the contrary, after solubilization with SDS, aO-1 and bO were modified by DCCD and NCD-4, which decreased the chromophore regeneration. In particular, the reaction of aO-1 in SDS with NCD-4 proceeded in a 1:1 ratio at neutral pH. The fluorescence and CD spectra indicated that the modified site was located in the hydrophobic, asymmetrical region. Lysyl-endopeptidase digestion of NCD-4 modified aO-1 produced a fluorescent fragment and amino acid sequence analysis showed that Asp85 or Asp96 in helix C is a probable candidate for the modified residue at present. Kinetic CD measurements revealed that the introduction of N-acylurea at an Asp residue in helix C did not affect the formation of the transient intermediate but inhibited the side chain packing during refolding.  (+info)

Active site characterization of RNase Rs from Rhizopus stolonifer: involvement of histidine and lysine in catalysis and carboxylate in substrate binding. (3/267)

Chemical modification studies on purified RNase Rs revealed the involvement of a single histidine, lysine and carboxylate residue in the catalytic activity of the enzyme. RNA could not protect the enzyme against DEP- and TNBS-mediated inactivation whereas, substrate protection was observed in case of EDAC-mediated inactivation of the enzyme. K(m) and k(cat) values of the partially inactivated enzyme samples suggested that while histidine and lysine are involved in catalysis, carboxylate is involved in substrate binding. Active site nature of RNase Rs suggests that the inability of the enzyme to readily convert 2',3'-cyclic nucleotides to 3'-mononucleotides is probably due to the absence of catalytically active second histidine residue.  (+info)

Structural and kinetic studies of the pyruvate-ferredoxin oxidoreductase/ferredoxin complex from Desulfovibrio africanus. (4/267)

The pyruvate-ferredoxin oxidoreductase (PFOR)/ferredoxin (Fd) system of Desulfovibrio africanus has been investigated with the aim of understanding more fully protein-protein interaction and the kinetic characteristics of electron transfer between the two redox partners. D. africanus contains three Fds (Fd I, Fd II and Fd III) able to function as electron acceptors for PFOR. The complete amino acid sequence of Fd II was determined by automatic Edman degradation. It revealed a striking similarity to that of Fd I. The protein consists of 64 residues and its amino acid sequence is in agreement with a molecular mass of 6822.5 Da as measured by electrospray MS. Fd II contains five cysteine residues of which the first four (Cys11, Cys14, Cys17 and Cys54) are likely ligands for the single [4Fe-4S] cluster. A covalently cross-linked complex between PFOR and Fd I or Fd II was obtained by using a water soluble carbodiimide. This complex exhibited a stoichiometry of one ferredoxin for one PFOR subunit and is dependent on the ionic strength. The second-order rate constants for electron transfer between PFOR and Fds determined electrochemically using cyclic voltammetry are 7 x 107 M-1.s-1 for Fd I and 2 x 107 M-1.s-1 for Fd II and Fd III. The Km values of PFOR for Fd I and Fd II measured both by the electrochemical and the spectrophotometric method have been found to be 3 microM and 5 microM, respectively. The three-dimensional modelling of Fd II and surface analysis of Fd I, Fd II and PFOR suggest that a protein-protein complex is likely to be formed between aspartic acid/glutamic acid invariant residues of Fds and lysine residues surrounding the distal [4Fe-4S] cluster of PFOR. All of these studies are indicative of the involvement of electrostatic interactions between the two redox partners.  (+info)

S-layer-coated liposomes as a versatile system for entrapping and binding target molecules. (5/267)

In the present study, unilamellar liposomes coated with the crystalline bacterial cell surface layer (S-layer) protein of Bacillus stearothermophilus PV72/p2 were used as matrix for defined binding of functional molecules via the avidin- or streptavidin-biotin bridge. The liposomes were composed of dipalmitoyl phosphatidylcholine, cholesterol and hexadecylamine in a molar ratio of 10:5:4 and they had an average size of 180 nm. For introducing specific functions into the S-layer lattice without affecting substances encapsulated within the liposomes, crosslinking and activation reagents had to be identified which did not penetrate the liposomal membrane. Among different reagents, a hydrophilic dialdehyde generated by periodate cleavage of raffinose and a sulfo-succinimide activated dicarboxylic acid were found to be impermeable for the liposomal membrane. Both reagents completely crosslinked the S-layer lattice without interfering with its regular structure. Biotinylation of S-layer-coated liposomes was achieved by coupling p-diazobenzoyl biocytin which preferably reacts with the phenolic residue of tyrosine or with the imidazole ring of histidine. By applying this method, two biotin residues accessible for subsequent avidin binding were introduced per S-layer subunit. As visualized by labeling with biotinylated ferritin, an ordered monomolecular layer of streptavidin was formed on the surface of the S-layer-coated liposomes. As a second model system, biotinylated anti-human IgG was attached via the streptavidin bridge to the biotinylated S-layer-coated liposomes. The biological activity of the bound anti-human IgG was confirmed by ELISA.  (+info)

An essential glutamyl residue in EmrE, a multidrug antiporter from Escherichia coli. (6/267)

EmrE is an Escherichia coli 12-kDa protein that confers resistance to toxic compounds, by actively removing them in exchange with protons. The protein includes eight charged residues. Seven of these residues are located in the hydrophilic loops and can be replaced with either Cys or another amino acid bearing the same charge, without impairing transport activity. Glu-14 is the only charged residue in the membrane domain and is conserved in all the proteins of the family. We show here that this residue is the site of action of dicyclohexylcarbodiimide, a carbodiimide known to act in hydrophobic environments. When Glu-14 was replaced with either Cys or Asp, resistance was abolished. Whereas the E14C mutant displays no transport activity, the E14D protein shows efflux and exchange at rates about 30-50% that of the wild type. The maximal DeltapH-driven uptake rate of E14D is only 10% that of the wild type. The mutant shows a different pH profile in all the transport modes. Our results support the notion that Glu-14 is an essential part of a binding domain shared by substrates and protons but mutually exclusive in time. This notion provides the molecular basis for the obligatory exchange catalyzed by EmrE.  (+info)

Identification and characterization of a novel cAMP receptor protein in the cyanobacterium Synechocystis sp. PCC 6803. (7/267)

Three open reading frames of Synechocystis sp. PCC 6803 encoding a domain homologous with the cAMP binding domain of bacterial cAMP receptor protein were analyzed. These three open reading frames, sll1371, sll1924, and slr0593, which were named sycrp1, sycrp2, and sypk, respectively, were expressed in Escherichia coli as His-tagged or glutathione S-transferase fusion proteins and purified, and their biochemical properties were investigated. The results obtained for equilibrium dialysis measurements using these recombinant proteins suggest that SYCRP1 and SYPK show a binding affinity for cAMP while SYCRP2 does not. The dissociation constant of His-tagged SYCRP1 for cAMP is approximately 3 microM. A cross-linking experiment using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide revealed that His-tagged SYCRP1 forms a homodimer, and the presence or absence of cAMP does not affect the formation of the homodimer. The amino acid sequence reveals that SYCRP1 has a domain similar to the DNA binding domain of bacterial cAMP receptor protein in the COOH-terminal region. Consistent with this, His-tagged SYCRP1 forms a complex with DNA that contains the consensus sequence for E. coli cAMP receptor protein in the presence of cAMP. These results strongly suggest that SYCRP1 is a novel cAMP receptor protein.  (+info)

Comparison of the efficiency of various coupling systems in the acylation of model secondary amines with thymin-1-ylacetic acid. (8/267)

Peptide nucleic acids (PNAs) make a promising group of DNA analogues. The backbone of typical PNA oligomers is composed of N-(2-aminoethyl)glycine units, linked by the peptide bonds. The backbone secondary amine groups are acylated with carboxyalkyl derivatives of nucleobases. One of the PNA synthesis step causing some problems is the acylation of the monomer backbone with the nucleobase derivatives. The aim of the study was to compare the efficiency of various coupling systems in the acylation. Simple model compounds (piperidine and proline) were used, as well as equimolar amounts of the coupling reagents. Selected systems based on carbodiimides, aminium or phosphonium salts, mixed anhydride, and active esters were tested.  (+info)

The molecular biology of human genetic disorders is under intensive investigation at present. In those cases where the disorder is clearly defined in terms of altered gene structure, possibilities may exist for the correction of the disorder by insertion of normal genes through the process of DNA transfection. A possible method for the transfer of genetic material is by attempting to attach DNA to a protein which has specific receptors on cells and which undergoes receptor-mediated endocytosis. By this means one might be able to get DNA into cells. This thesis deals with experimental work on the chemical modification of human serum transferrin by means of water-soluble carbodiimides. The resulting N-acylurea transferrins bind DNA in a reversible manner. Characteristics and properties of the binding interactions are dealt with in detail. N-acylurea derivatives of transferrin were prepared with the water-soluble carbodiimides, N-ethyl-N -(3-dimethylaminopropyl) carbodiimide and N-ethyl-N ...

Fabrication of a human recombinant collagen-based corneal substitute using carbodiimide chemistryFabrication of a human recombinant collagen-based corneal substitute using carbodiimide chemistry
Human recombinant collagen can be cross-linked with a variety of chemical cross-linking agents. Cross-linking methods can be tuned to confer collagen-based scaffolds with specific physical properties, improved antigenicity and thermal stability without impeding the ability of the material to integrate into the surrounding tissue and to promote regeneration. Here, we describe a method to cross-link human recombinant collagen using a water soluble carbodiimide. Carbodiimides are referred to as zero-length cross-linking agents as they are not incorporated into the final cross-link and thus pose minimal risk with respect to cytotoxicity. The resulting collagen-based scaffold possesses properties comparable to that of the human cornea and is thus suitable for use as a corneal substitute.. ...

Carbodiimide inactivation of MMPs and effect on dentin bonding. - Semantic ScholarCarbodiimide inactivation of MMPs and effect on dentin bonding. - Semantic Scholar
The use of protein cross-linking agents during bonding procedures has been recently proposed to improve bond durability. This study aimed to use zymography and in situ zymography techniques to evaluate the ability of 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) cross-linker to inhibit matrix metalloproteinase (MMP) activity. The hypotheses tested were that: (1) bonding procedures increase dentin gelatinolytic activity and (2) EDC pre-treatment prevents this enzymatic activity. The zymographic assay was performed on protein extracts obtained from dentin powder treated with Optibond FL or Scotchbond 1XT with or without 0.3M EDC pre-treatment.

Biodegradable injectable sheet as transscleral drug delivery system | IOVS | ARVO JournalsBiodegradable injectable sheet as transscleral drug delivery system | IOVS | ARVO Journals
Purpose : To evaluate the in vitro and in vivo drug release of a biodegradable injectable sheet made of cross-linked chitosan and gelatin mixture. Methods : Gelatin and chitosan were solved in water and 1% acetic acid at concentrations of 5 wt% and 2.5 wt%, respectively. Then, 5 wt% gelatin and 2.5 wt% chitosan was mixed at the ratio of 3 : 2 (vol). The drug was mixed with the 3 wt% gelatin/1 wt% chitosan mixture. Fluorescein isothiocyanate (FITC), FITC-labeled dextran 150 kDa (FD150), and FITC-labeled albumin (FITC-ALB) were used as drugs. Immedeately after adding water soluble carbodiimide in the gelatin/chitosan/drug mixture at final concentration of 10 mg/mL, 3 μL of the mixture was cast in the polydimethylsilane (PDMS) mold (internal diameter; 2.76 mm, depth; 0.5 mm). Then, the cross-linked gels were dried for 1 hour at room temperutere to make flexible sheets. The sheets were incubated in phosphate buffered saline (PBS) at 37 degrees C.

Ferrocenyl derivatives exhibit antitumor (Jaouen et al., 2004), antibacterial (Fouda et al., 2007), antifungal and antimalarial (Biot et al., 2004) activities. It was proved that the replacement of the aromatic group by the ferrocenyl moiety in penicillins and cephalosporins could improve their antibiotic activity (Edwards et al., 1975). Against this background, the title compound was chosen for X-ray structure analysis (Fig. 1).. In the title compound, the benzene ring makes dihedral angles of 10.84 (9) and 12.35 (9)°, respectively, with the substituted and unsubstituted cyclopentadienyl (Cp) rings of the ferrocenyl unit. In ferrocenyl unit, the two Cp rings are planar and are parallel to each other with a dihedral angle of 1.56 (9)° between them. The Fe atom lies in the middle of the two planes of Cp rings. The distances of the Fe1 atom from the centroids of the substituted and unsubstituted cyclopentadienyl rings are 1.646 (10) and 1.650 (12) Å, respectively. The Cg1-Fe1-Cg2 angle is ...

To establish the role of the ferrocenyl moiety in the antiplasmodial activity of ferroquine, compounds in which this moiety is replaced by the corresponding ruthenium-based moieties were synthesized and evaluated. In both the sensitive (D 10) and resistant (K1) strains of Plasmodium falciparum, ruthenoquine analogues showed comparable potency to ferroquine. This suggests that a probable role of the ferrocenyl fragment is to serve simply as a hydrophobic spacer group. In addition, ferroquine analogues with different aromatic substituents were synthesized and evaluated. Unexpectedly high activity for quinoline compounds lacking the 7-chloro substituent suggests the ferrocenyl moiety may have an additive and/or synergistic effect. (c) 2007 Elsevier Ltd.

Bicomponent electrospun nanofibers based on the combination of synthetic (i.e., aliphatic polyesters such as polycaprolactone (PCL)) and natural proteins (i.e., gelatin) have been extensively investigated as temporary platforms to instruct cells by the release of molecular/pharmaceutical signals for the regeneration of several tissues. Here, water soluble proteins (i.e., gelatin), strictly embedded to PCL, act as carriers of bioactive molecules, thus improving bioavailability and supporting cell activities during in vitro regeneration. However, these proteins are rapidly digested by enzymes, locally produced by many different cell types, both in vitro and in vivo, with significant drawbacks in the control of molecular release. Hence, we have investigated three post-processing strategies based on the use of different crosslinking agents-(1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride) (EDC), glyceraldehyde (GC), and 1,4-butanediol diglycidyl ether (BDDGE)-to delay the dissolution time of

The photosystem II subunit PsbS is essential for excess energy dissipation (qE); however, both lutein and zeaxanthin are needed for its full activation. Based on previous work, two models can be proposed in which PsbS is either 1) the gene product where the quenching activity is located or 2) a proton-sensing trigger that activates the quencher molecules. The first hypothesis requires xanthophyll binding to two PsbS-binding sites, each activated by the protonation of a dicyclohexylcarbodiimide-binding lumen-exposed glutamic acid residue. To assess the existence and properties of these xanthophyll-binding sites, PsbS point mutants on each of the two Glu residues PsbS E122Q and PsbS E226Q were crossed with the npq1/npq4 and lut2/ npq4 mutants lacking zeaxanthin and lutein, respectively. Double mutants E122Q/npq1 and E226Q/npq1 had no qE, whereas E122Q/lut2 and E226Q/lut2 showed a strong qE reduction with respect to both lut2 and single glutamate mutants. These findings exclude a specific ...

0281] Materials Preparation--To activate the labeling beads, one ml of 0.2 μm Time Resolved Fluorescence latex microparticles (MPs) (Thermo Fisher Fremont, Calif.) at 10% (w/v) solids are combined with 1 ml of 0.5 M MES buffer (pH 6.0), 5.5 ml of deionized H20, 2.3 ml of 50 mg of N-hydroxysuccinimide (ISIHS; Product #24500; Pierce Chemical Company, Rockford, Ill.) per ml deionized H2O and 0.2 ml of 5 mg of 1-ethyl-3-(3-dimethylamino-propyl) carbodiimide hydrochloride (EDC; Product #22980; Pierce Chemical Company) in deionized H2O. The resultant mixture is sonicated on ice for 40 seconds and then allowed to react on a shaker at RT for 30 minutes. The activated MPs are then centrifuged at 100 C at 10,000×g and washed three times with cold 50 mM MES buffer (pH 6.0) by resuspension and centrifugation cycles. In a typical procedure, the final pellet of MPs is suspended in 3.7 ml of 50 mM MES buffer (pH 6.0) and 2.3 ml of 1.0 mg of mouse anti-(Anti-NTproBNP peptide 63-71 antibody (Hytest., Turku, ...

Human serum albumins modified by covalently bound tolmetin or zomepirac were synthesized as models for similar products formed in vivo from acyl glucuronides. Activated esters of both drugs were prepared with 1-ethyl-3-(3-dimethylaminopropyl)-carbodi-imide, and then allowed to react with human serum albumin. Tryptic digests of both protein products were analysed by HPLC to identify peptides containing covalently bound drugs, and binding sites on albumin were identified by high-performance tandem MS. Three binding sites were common to both products, i.e. lysine-195, -199 and -351. Three further modified residues were identified for the tolmetin-albumin product, i.e. aspartic acid 1, and lysine-524 and -536. ...

Biotage - Biotage® PS-HOBt(HL)Biotage - Biotage® PS-HOBt(HL)
Download the product note.. Biotage®PS-HOBt(HL) is a sulfonamide-linked, polymer supported equivalent of 1-hydroxybenzotriazole (HOBt). PS-HOBt(HL) is used to generate bound HOBt active esters, which can either be made and used in situ, or isolated and stored as stable intermediates. Treatment of bound HOBt esters with an amine leads to amide formation in generally high purity without the need for further purification.. To date, the recommended procedure for loading PS-HOBt has required PyBroP as the coupling agent. We have developed an improved loading procedure based on the use of diisopropylcarbodiimide and DMAP. The new procedure has proven to be much more reliable, efficient, and cost effective. It requires fewer equivalents of carboxylic acid and does not require a double coupling as is the case when PyBroP is used.. Polymer-supported active esters offer some unique advantages for parallel amide synthesis. The polymer-supported active esters of PS-HOBt(HL) can be prepared using the ...

Patent US7918899 - Variably crosslinked tissue - Google PatentsPatent US7918899 - Variably crosslinked tissue - Google Patents
Non-glutaraldehyde fixation of an organ or a prosthesis for implantation in a mammal is based upon carbodiimide treatment. A solution containing a sterilizing agent, such as EDC, in combination with a coupling enhancer, such as Sulfo-NHS, and a high concentration of a diamine cross linking agent is used. As a result, only minimal surface reduction occurs during fixation, and the resultant products show a dramatic increase in resistance to calcification.
