CRYSTAL STRUCTURE OF THE MODULAR CPL-1 ENDOLYSIN COMPLEXED WITH A PEPTIDOGLYCAN ANALOGUE (E94Q MUTANT)
Overview
Pneumococcal bacteriophage-encoded lysins are modular proteins that have, been shown to act as enzymatic antimicrobial agents (enzybiotics) in, treatment of streptococcal infections. The first X-ray crystal structures, of the Cpl-1 lysin, encoded by the pneumococcal phage Cp-1, in complex, with three bacterial cell wall peptidoglycan (PG) analogues are reported, herein. The Cpl-1 structure is folded in two well-defined modules, one, responsible for anchoring to the pneumococcal cell wall and the other, a, catalytic module, that hydrolyzes the PG. Conformational rearrangement of, Tyr127 is a critical event in molecular recognition of a stretch of five, saccharide rings of the polymeric peptidoglycan (cell wall). The PG is, bound at a stretch of the surface that is defined as the, ... [(full description)]
