Protein
Stage 0 sporulation protein A
Organism
Bacillus cereus (strain ATCC 14579 / DSM 31 / JCM 2152 / NBRC 15305 / NCIMB 9373 / NRRL B-3711)
Function
May play the central regulatory role in sporulation. It may be an element of the effector pathway responsible for the activation of sporulation genes in response to nutritional stress. Spo0A may act in concert with Spo0H (a sigma factor) to control the expression of some genes that are critical to the sporulation process. Repressor of abrB, activator of the spoIIa operon. Binds the DNA sequence 5'-TGNCGAA-3' (0A box) (By similarity).
