General Information

General Information Comment Organism
physiological function gene 7942dgdA encodiung digalactosyldiacylglycerol synthase is essential. 7942dgdA can be knocked out only when genes for cyanobacterial or plant digalactosyldiacylglycerol synthases are expressed. Lack of digalactosyldiacylglycerol cannot be compensated by the other membrane lipids in Synechococcus elongatus PCC 7942 or by glucosylgalactosyldiacylglycerol synthesized by the beta-GlcT gene of Chloroflexus aurantiacus. Digalactosyldiacylglycerol has an indispensable role and the second galactose molecule is the key Synechococcus elongatus
