  • Title: Penicillin-binding proteins 1a and 1b form independent dimers in Escherichia coli.
    Author: Charpentier X, Chalut C, Rémy MH, Masson JM.
    Journal: J Bacteriol; 2002 Jul; 184(13):3749-52. PubMed ID: 12057973.
    Abstract:
    We report here that PBP1a can dimerize but does not interact with PBP1b to form PBP1a/PBP1b heterodimers in Escherichia coli. These findings support the idea of a relevant involvement of dimerization of both PBP1a and PBP1b during murein synthesis and suggest the existence of different peptidoglycan synthesis complexes.
