'ManuscriptPro PDF Search' digitally communicates with online databases that contain selected information from scientific journals. The implications of this substrate specificity of NG PBP3 with respect to its possible role in cell wall biosynthesis, and for understanding the substrate specificity of the LMM PBPs in general, are discussed. NG PBP3 demonstrated low selectivity for gamma-d-Glu vs d-IsoGln and for the presence or absence of the terminal l-Ala residue. This observation suggests that NG PBP3 is specific for the approximately d-Ala-d-Ala moiety of pentapeptides engaged in cross-links in the bacterial cell wall, such that NG PBP3 would act after transpeptidase-catalyzed reactions generate the acylated amino group required for its specificity. NG PBP3 demonstrated good catalytic efficiency (2.5 x 10(5) M(-1) s(-1)) with the best of these substrates, with a pronounced preference (50-fold) for N(epsilon)-acylated substrates over N(epsilon)-nonacylated substrates. The capacity of these peptides to serve as substrates for Neisseria gonorrhoeae (NG) PBP3 was assessed.

A series of eight substrates, based on variation of the pentapeptide Boc-l-Ala-gamma-d-Glu-l-Lys-d-Ala-d-Ala, were synthesized to test specificity for three features of PBP substrates: (1) the presence or absence of an N(epsilon)-acyl group, (2) the presence of d-IsoGln in place of gamma-d-Glu, and (3) the presence or absence of the N-terminal l-Ala residue. Despite their importance, their roles in cell wall biosynthesis remain enigmatic. Penicillin-binding proteins (PBPs) are bacterial enzymes involved in the final stages of cell wall biosynthesis and are the lethal targets of beta-lactam antibiotics.
