CC   -!- FUNCTION: Ambiactive repressor and activator of the transcription of
CC       genes expressed during the transition state between vegetative growth
CC       and the onset of stationary phase and sporulation. It controls the
CC       expression of genes spovG and tycA. AbrB binds to the tycA promoter
CC       region at two A- and T-rich sites, it may be the sole repressor of tycA
CC       transcription. {ECO:0000269|PubMed:2504584}.
