  Aminolytic reaction catalyzed by d-stereospecific amidohydrolases from Streptomyces spp

  摘要：

  From investigation of 2000 soil isolates, we identified two serine-type amidohydrolases that can hydrolyze D-aminoacyl derivatives from the culture supernatant of Streptomyces species 82F2 and 83D12. The enzymes, redesignated as 82F2-DAP and 83D12-DAP, were purified for homogeneity and characterized. Each enzyme had molecular mass of approximately 40 kDa, and each showed moderate stability with respect to temperature and pH. Among hydrolytic activities toward D-aminoacyl-pNAs, the enzymes showed strict specificity toward D-Phe-pNA, but showed broad specificity toward D-aminoacyl esters. The specific activity for D-Phe-pNA hydrolysis of 82F2-DAP was ten-fold higher than that of 83D12-DAP. As a second function, each enzyme showed peptide bond formation activity by its function of aminolysis reaction. Based on results of D-Phe D-Phe synthesis under various conditions, we propose a reaction mechanism for D-Phe D-Phe production. Furthermore, the enzymes exhibited peptide elongation activity, producing oligo homopeptide in a one-pot reaction. We cloned the genes encoding each enzyme, which revealed that the primary structure of each enzyme showed 30-60% identity with those of peptidases belonging to the clan SE, S12 peptidase family categorized as serine peptidase with D-stereospecificity.

  these compounds. Reducing the ring size gave much less potent compounds. The most potent analogue of the series, CO(CH2)2CHPhCO-D-Phe-Lys-D-Trp-NH(CH2)2CHMe (14, IC50 = 26 nM), was obtained by substituting the methylene group nearer to the D-Phe residue by a -CHPh- group. Compound 14 was 15-fold more potent in inhibiting human renin than porcine renin.

  ligand N(alpha)-[(5-dimethylamino-1-naphthalenesulfonyl)aminoethyl]-N(1)-propyl-phenylal aninamide, which has the same binding site and absolute configuration as 4, showed very low chiral discrimination ability. The enantioselectivity in fluorescence response was found to be due to the formation of diastereomeric ternary complexes, which were detected by ESI-MS and by circular dichroism. Time-resolved
