UniProtKB - P08874 (ABRB_BACSU)
Protein
Transition state regulatory protein AbrB
Gene
abrB
Organism
Bacillus subtilis (strain 168)
Status
Functioni
Ambiactive repressor and activator of the transcription of genes expressed during the transition state between vegetative growth and the onset of stationary phase and sporulation. It controls the expression of genes spovG and tycA. AbrB binds to the tycA promoter region at two A- and T-rich sites, it may be the sole repressor of tycA transcription.1 Publication
Caution
It is uncertain whether Met-1 or Met-3 is the initiator.Curated
