Involvement of sulfoquinovosyl diacylglycerol in DNA synthesis in Synechocystis sp. PCC 6803
Abstract Background Sulfoquinovosyl diacylglycerol m&m speckled eggs (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 S
