cell division inhibition protein DicB
DicB is part of the dic operon, which resides on cryptic prophage Kim. Under normal conditions, expression of dicB is actively repressed. When expression is induced, however, cell division rapidly ceases, and this division block is dependent on MinC with which it interacts [2]. [1]. 2836697. Cell division inhibition gene dicB is regulated by a locus similar to lambdoid bacteriophage immunity loci. Bejar S, Bouche F, Bouche JP;. Mol Gen Genet 1988;212:11-19. [2]. 12003935. Targeting of (D)MinC/MinD and (D)MinC/DicB complexes to septal rings in Escherichia coli suggests a multistep mechanism for MinC-mediated destruction of nascent FtsZ rings.
