Fig. 1From: Increasing n-butanol production with Saccharomyces cerevisiae by optimizing acetyl-CoA synthesis, NADH levels and trans-2-enoyl-CoA reductase expressionSimplified metabolic pathway for CoA biosynthesis in Saccharomyces cerevisiae. Shown are the relevant steps in yeast’s metabolism for endogenous synthesis of free CoA. The precursor pantothenate can be taken from medium via transporter Fen2 or can be synthesized endogenously from amino acidsBack to article page
