Figure 1From: Enhancing the production of S-adenosyl-L-methionine in Pichia pastoris GS115 by metabolic engineeringMetabolic network of homocysteine in P. pastoris GS115 strain. The illustration represents the homocysteine recycling and the transsulfuration pathway. Solid lines indicate reactions that are common in both yeast and mammals, whereas dotted lines are unique to yeast.Back to article page
