Nucleotide sequence and homology comparison of two genes of the sulfate transport operon from the cyanobacterium Synechocystis sp. PCC 6803.
The genome of Synechocystis sp. PCC 6803 contains an operon with homology to the sulfate permease of other prokaryotes. We used antibodies raised against cytoplasmic membrane protein to find three genes with strong homology to sbpA, orf81 and cysT genes of the cyanobacterium Synechococcus sp. PCC 7942, Escherichia coli, Salmonella typhimurium and Marchantia polymorpha. It is likely that the permease genes are expressed and the proteins are inserted into the cytoplasmic membrane.
