Fig. 1From: Over-expression of an electron transport protein OmcS provides sufficient NADH for d-lactate production in cyanobacteriumEffects of OmcS on the expression of central metabolism genes in Syn2973. Cells grew for 12 and 36Â h, respectively. The Log2Ratio is shown for each gene on heat maps. 1, Syn2973; 2, Syn2973-Ldh; 3, Syn2973-LdhOmcS. The upregulated genes of each pathway are red. Black arrows represent LET, which generates ATP and NADPH coupled. Red arrows represent NDH-dependent CET and light grey arrows represent PGR5-dependent CET. Yellow arrows represent RET. To make it convenient for understanding, we use the protein name instead of the gene nameBack to article page
