Protein
Transition state regulatory protein AbrB
Organism
Bacillus subtilis (strain 168)
Function
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.
Similarity
To B.subtilis Abh and SpoVT.
