Fig. 8From: Phylogenetics-based identification and characterization of a superior 2,3-butanediol dehydrogenase for Zymomonas mobilis expression2,3-Butanediol dehydrogenase activity of purified Bdh enzyme variants. Bdh activity was measured by following NADH consumption at 340Â nm. Purified proteins were used for the enzyme assay. Reactions were carried out in triplicates and are represented as mean SDBack to article page
