Pfr, in turn, can be converted back to Pr by far-red light known as photoreversibility

A second glycoprotein secreted during starvation is CMF (conditioned medium factor)

#Unit 5. Developmental Biology

Histidine phosphatase activity of DhkA causes inactivation of RegA, the accumulation of cAMP and PKA activation, causes spore maturation.

#Unit 5. Developmental Biology

CMF stimulates gene expression in parallel with PSF, and both signals potentiate cAMP signaling by inducing genes involved in cAMP synthesis and detection
