PBP1 is a component of the Bacillus subtilis cell division machinery.
Bacillus subtilis penicillin-binding protein PBP1 has been implicated in cell division. We show here that a PBP1 knockout strain is affected in the formation of the asymmetric sporulation septum and that green fluorescent protein-PBP1 localizes to the sporulation septum. Localization of PBP1 to the vegetative septum is dependent on various cell division proteins. This study proves that PBP1 forms part of the B. subtilis cell division machinery.
