Fatty acid biosynthesis, malonyl-CoA generation as well as the metabolic regulation strategy in Synechocystis. Fatty acid biosynthesis depends on the key precursor including acetyl-CoA and malonyl-CoA as well as the key enzymes like FabH, FabF, and FabD. Downregulation of the expression of the key genes using the Hfq-MicC tool would alter the generation of fatty acid and promote the accumulation of malonyl-CoA
