A response regulator Rre37 and an RNA polymerase sigma factor SigE represent two parallel pathways to activate sugar catabolism in a cyanobacterium Synechocystis sp. PCC 6803.

Abstract excerpt

Sugar catabolic genes are induced during nitrogen starvation in a cyanobacterium Synechocystis sp. PCC 6803, but the underlying regulatory mechanism still remains to be completely characterized. In this study, we showed by molecular genetics and transcriptome analyses that a response regulator Rre37 (encoded by sll1330), whose expression is enhanced by nitrogen depletion under the control of NtcA, activates...
