pCooF Promoter from Rhodospirillum rubrum

Rhodospirillum rubrum is able to use CO as an carbon source with its CO-sensing protein called CooA. CooA activates the transcription of genes encoding the CO-oxidation (coo) regulon which produces the proteins needed for the utilization of CO. CooA binds to a position overlapping the -35 element of the P(cooF) promoter, similar to the arrangement of class II CRP (cAMP receptor protein)- and FNR (fumarate and nitrate reductase activator protein)-dependent promoters when expressed in Escherichia coli. The two CO regulated transcriptional units, cooMKLXUH and cooFSCTJ, is responsible for the CO-dependent anaerobic growth of Rhodospirillum rubrum and enable the bacteria to oxidize CO . The coo regulon has three main products which are listed as O2-sensitive CO dehydrogenase (CooS), CooS-associated Fe-S protein (CooF), CO-tolerant hydrogenase (CooH). CooA is responsible for the expression of the genes of these proteins and activates by sensing CO in anaerobic environments. Because of the lack of active CooA, CO-independent basal level transcription of PcooF is not detectable.
