Fig. 1From: Microbial 2-butanol production with Lactobacillus diolivoransMetabolic pathways for the formation of 1-propanol, 1,3-propanediol and 2-butanol. The two major enzymes present in L. diolivorans, catalysing these reactions, are a vitamin B12-dependent diol dehydratase (PduCDE) and an alcohol dehydrogenase (pduQ)Back to article page
