Characterization of a 38 kDa penicillin-binding protein and its possible involvement in maintaining stationary-phase cells of Shigella dysenteriae.
This paper reports the first attempt to characterize the penicillin-binding proteins (PBPs) of Shigella dysenteriae, an important human pathogen. The PBP pattern of the membranes of S. dysenteriae closely resembles that of Escherichia coli membranes. A 38 kDa PBP which is an important target for the penem SCH34343, the cephamycin cefoxitin and the oxacephem moxalactam, has been purified. This PBP is immunologically related to a PBP of similar molecular mass in E. coli and is present at high levels in stationary-phase cells of S. dysenteriae.
