Involvement of sulfoquinovosyl diacylglycerol in DNA synthesis in Synechocystis sp. PCC 6803
Abstract Background Sulfoquinovosyl diacylglycerol (SQDG) is present in the membranes of cyanobacteria and their postulated progeny, plastids, in plants.A cyanobacterium, Synechocystis sp.PCC 6803, requires SQDG for growth: its mutant (SD1) with the sqdB gene for SQDG synthesis disrupted can grow with external supplementation of SQDG.However, upon
