Interestingly , the regulation of the stiB locus ( unlike that of stiC ) was unaffected by a cya mutation , suggesting that cAMP-receptor-protein acts with a different signal-molecule in the repression of stiB .

This putative repressor would not function during log phase ; the repression of stiB during log phase is mediated by cAMP-receptor-protein in a cAMP-independent manner .
