Four novel Synechocystis sp. strain PCC 6803 genes (sll1495, sll0804, slr1306, and slr1125) which encode hypothetical proteins were determined by transposon mutagenesis to be required for optimal photoautotrophic growth. Mutations were also recovered in ccmK4, a carboxysome coat protein homologue, and me, the decarboxylating NADP+-dependent malic enzyme. This is the first report that these known genes are required for optimal photoautotrophy.
