摘要：

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.
