THE CHEMISTRY OF PEPTIDES RELATED TO METABOLITES OF TRICHODERMA SPP. 2. AN IMPROVED METHOD OF CHARACTERIZATION OF PEPTIDES OF 2-METHYLALANINE

4-Chlorobenzoylazide reacts with amino acid and peptide esters to give the 4-chlorobenzoyl derivatives in 60-90percent yield, at room temperature, without measurable racemization.The reaction also proceeds smoothly with hindered amines such as methyl 2-methylalaninate and with secondary amines, e.g. methyl L-prolyl-L-valinate.Ten examples of the reaction are reported with peptides, synthesized for the purpose, that might be accessible from hydrolysates of the numerous fungal metabolites now known, which contain a high proportion of 2-methylalanine.The derivatives of di-, tri-, tetra-, and pentapeptides were highly crystalline, with sharp melting points, and could be detected and integrated in the effluent from chromatography columns at about the 10-ng level.This simple method of derivatization might be usefully applied to the resolution of discrepancies in the physical properties of ostensibly the same 2-methylalanyl peptide prepared in different laboratories.

Selectivity and Specificity in Substrate Binding to Proteases: Novel Hydrolytic Reactions Catalysed by alpha-Chymotrypsin Suspended in Organic Solvents with Low Water Content and Mediated by Ammonium Hydrogen Carbonate

alpha-Chymotrypsin suspended in organic solvents with low water content catalysed hydrolytic reactions in the presence of ammonium hydrogen carbonate.Molecular modelling studies were carried out and structure-reactivity relationships were established by studying the hydrolysis of amino acid derivatives and analogues.The enzyme was found to be stereoselective with respect to the hydrolysis of L-amino acid derivatives, but no stereoselectivity was observed when alpha-hydroxy esters were used as substrates.A general procedure for the resolution of aromatic amino acid esters is given.The results are interpreted in terms of molecular modelling based on X-ray crystallographic data and literature data.
