    Structure, Mechanism, and Substrate Profile for Sco3058: The Closest Bacterial Homologue to Human Renal Dipeptidase,
    摘要:
    Human renal dipeptidase, an enzyme associated With glutathione metabolism and the hydrolysis of beta-lactams, is similar in sequence to a cluster of similar to 400 microbial proteins currently annotated as nonspecific dipeptidases within the amidohydrolase superfamily. The closest homologue to the human renal dipeptidase from a Fully sequenced microbe is Sco3058 from Streptomyces coelicolor. Dipeptide Substrates of Sco3058 were identified by screening a comprehensive series Of L-Xaa-L-Xaa, L-Xaa-D-Xaa, and D-Xaa-L-Xaa dipeptide libraries. The substrate specificity profile shows that Sco3058 hydrolyzes a broad range of dipeptides with a marked preference for all L-amino acid at the N-terminus and a D-amino acid at the C-terminus. The best Substrate identified was L-Arg-D-Asp (k(eat)/K-m = 7.6 x 10(5) M-1 s(-1)). The three-dimensional structure of Sco3058 was determined in the absence and presence of the inhibitors citrate and a phosphinate mimic Of L-Ala-D-Asp. The enzyme folds as (beta/alpha)(8) barrel, and two zinc Ions are bound in the active site. Site-directed mutagenesis was used to probe the importance of specific residues that have direct interactions with the substrate analogues in the active site (Asp-22, His-150, Arg-223, and Asp-320). The solvent viscosity and kinetic effects of D2O indicate that Substrate binding is relatively sticky and that proton transfers do not occur during the rate-limiting step. A bell-shaped pH-rate profile for k(cat) and k(cat)/k(m) indicated that one group needs to he deprotonated and a second group Must be protonated for optimal turnover. Computational docking of high-energy intermediate forms Of L/D-Ala-L/D-Ala to the three-dimensional Structure of Sco3058 identified the Structural determinants for the stereochemical preferences for Substrate binding and turnover.
