The amino acid sequence around four cysteine residues in trout actin.

ABSTRACT: Four unique carboxymethylcysteine-containing peptides were isolated from tryptic and chymotryptic digests of trout muscle actin carboxymethylated with iodo[2-(14)C]acetic acid in 6m-guanidinium chloride. The amino acid sequences of these peptides were determined and showed a high degree of homology with the corresponding sequences from rabbit actin. One of the radioactive peptides was the C-terminal peptide and another sequence probably contained the cysteine residue from the N-terminal region of the protein.

The amino acid sequence around the active-site cysteine and histidine residues of stem bromelain.

Project description:Stem bromelain that had been irreversibly inhibited with 1,3-dibromo[2-(14)C]-acetone was reduced with sodium borohydride and carboxymethylated with iodoacetic acid. After digestion with trypsin and alpha-chymotrypsin three radioactive peptides were isolated chromatographically. The amino acid sequences around the cross-linked cysteine and histidine residues were determined and showed a high degree of homology with those around the active-site cysteine and histidine residues of papain and ficin.

The amino acid sequence around the active-site cysteine and histidine residues, and the buried cysteine residue in ficin.

Project description:Ficin that had been prepared from the latex of Ficus glabrata by salt fractionation and chromatography on carboxymethylcellulose was completely and irreversibly inhibited with 1,3-dibromo[2-(14)C]acetone and then treated with N-(4-dimethylamino-3,5-dinitrophenyl)maleimide in 6m-guanidinium chloride. After reduction and carboxymethylation of the labelled protein, it was digested with trypsin and alpha-chymotrypsin. Two radioactive peptides and two coloured peptides were isolated chromatographically and their sequences determined. The radioactive peptides revealed the amino acid sequences around the active-site cysteine and histidine residues and showed a high degree of homology with the omino acid sequence around the active-site cysteine and histidine residues in papain. The coloured peptides allowed the amino acid sequence around the buried cysteine residue in ficin to be determined.

Amino acid sequences around the cysteine residues of rabbit muscle triose phosphate isomerase.

Project description:1. The nature of the subunits in rabbit muscle triose phosphate isomerase has been investigated. 2. Amino acid analyses show that there are five cysteine residues and two methionine residues/subunit. 3. The amino acid sequences around the cysteine residues have been determined; these account for about 75 residues. 4. Cleavage at the methionine residues with cyanogen bromide gave three fragments. 5. These results show that the subunits correspond to polypeptide chains, containing about 230 amino acid residues. The chains in triose phosphate isomerase seem to be shorter than those of other glycolytic enzymes.

Clustering of Aromatic Amino Acid Residues around Methionine in Proteins.

Project description:Short-range, non-covalent interactions between amino acid residues determine protein structures and contribute to protein functions in diverse ways. The interactions of the thioether of methionine with the aromatic rings of tyrosine, tryptophan, and/or phenylalanine has long been discussed and such interactions are favorable on the order of 1-3 kcal mol-1. Here, we carry out a new bioinformatics survey of known protein structures where we assay the propensity of three aromatic residues to localize around the [-CH2-S-CH3] of methionine. We term these groups "3-bridge clusters". A dataset consisting of 33,819 proteins with less than 90% sequence identity was analyzed and such clusters were found in 4093 structures (or 12% of the non-redundant dataset). All sub-classes of enzymes were represented. A 3D coordinate analysis shows that most aromatic groups localize near the CH2 and CH3 of methionine. Quantum chemical calculations support that the 3-bridge clusters involve a network of interactions that involve the Met-S, Met-CH2, Met-CH3, and the π systems of nearby aromatic amino acid residues. Selected examples of proposed functions of 3-bridge clusters are discussed.

The amino acid sequence around the reactive cysteine residue in human plasma Factor XII.

Project description:1. Activated human plasma factor XIII was 65% inhibited by iodo[(14)C]acetate and incorporated 0.6 mol of label into the alpha subunit, which eventually was allowed to form a precipitate. 2. All the label was recovered as S-carboxymethylcysteine in a tetra-peptide of sequence Gly-Gln-Cys-Trp.

Amino acid sequence around lipoic acid residues in the pyruvate dehydrogenase multienzyme complex of Escherichia coli.

Project description:Amino-acid sequences around two lipoic acid residues in the lipoate acetyltransferase component of the pyruvate dehydrogenase complex of Escherichia coli were investigated. A single amino acid sequence of 13 residues was found. A repeated amino acid sequence in the lipoate acetyltransferase chain might explain this result.

A diagonal paper-electrophoretic technique for studying amino acid sequences around the cysteine and cystine residues of proteins.

Project description:1. A diagonal electrophoretic technique for studying the amino acid sequence around cysteine and cystine residues in proteins is described. The residues are first converted into S-aminoethylcysteine, and the protein is then treated with S-ethyl trifluorothioacetate, which trifluoroacetylates all the protein amino groups. The modified protein is digested enzymically and the resulting peptides are separated by paper electrophoresis. After exposure of the peptides on the paper to ammonia vapour, the electrophoresis is repeated, this time at right angles to the original direction. Peptides from which a trifluoroacetyl group is removed by the ammonia treatment will vacate the 45 degrees diagonal formed by all other unaffected peptides owing to the exposure of an additional amino group and consequent increased electrophoretic mobility towards the cathode. Peptides containing lysine or S-aminoethylcysteine are readily purified by this technique. 2. The successful application of the technique to bovine insulin is described. 3. Various methods for distinguishing peptides containing lysine from those containing S-aminoethylcysteine in more complicated proteins are suggested and discussed.

Amino acid sequences around the cysteine residue of calf lens -crystallin.

Project description:1. Calf lens alpha-crystallin was carboxymethylated with radioactive sodium iodoacetate to label the thiol group. 2. The protein was then digested with trypsin or alternatively fractionated in urea to obtain the acidic (A) chains, which were then digested with trypsin. Either procedure gave two radioactive peptides containing carboxymethylcysteine. 3. These two peptides were closely related: the longer form contained 28 amino acid residues, and the shorter lacked two residues at the N-terminal end of the longer form. 4. The amino acid sequence of the peptides have been determined. 5. No evidence for the presence of more than one cysteine residue/chain was found. 6. The question of the molecular weight of the chains is discussed.

Amino acid patterns around disulfide bonds.

Project description:Disulfide bonds provide an inexhaustible source of information on molecular evolution and biological specificity. In this work, we described the amino acid composition around disulfide bonds in a set of disulfide-rich proteins using appropriate descriptors, based on ANOVA (for all twenty natural amino acids or classes of amino acids clustered according to their chemical similarities) and Scheffé (for the disulfide-rich proteins superfamilies) statistics. We found that weakly hydrophilic and aromatic amino acids are quite abundant in the regions around disulfide bonds, contrary to aliphatic and hydrophobic amino acids. The density distributions (as a function of the distance to the center of the disulfide bonds) for all defined entities presented an overall unimodal behavior: the densities are null at short distances, have maxima at intermediate distances and decrease for long distances. In the end, the amino acid environment around the disulfide bonds was found to be different for different superfamilies, allowing the clustering of proteins in a biologically relevant way, suggesting that this type of chemical information might be used as a tool to assess the relationship between very divergent sets of disulfide-rich proteins.
