Fig. 5From: Cofactor engineering to regulate NAD+/NADH ratio with its application to phytosterols biotransformationBiotransformation pathways from phytosterols to AD (D) by MNR [20, 36, 37]. According to the protein analysis of MNR, the red line represents the up-regulated pathway of MNR cultured with phytosterols; the green line represents the down-regulated pathway of MNR cultured with phytosterolsBack to article page
