Fig. 1From: Growth optimization and identification of an ω-transaminase by a novel native PAGE activity staining method in a Bacillus sp. strain BaH isolated from Iranian soilω-TA activity towards different substrates. a ω-TA catalyzed reaction of (rac)-MBA with α-keto acid such as pyruvate. b Color developing process in ω-TA reaction by using ortho-xylylenediamine (OXD) as amine donor. R and R’ refer to the residues defined by the substrate specifity of the applied enzyme, amine group was highlighted to show how amine group is stereospecifically transferred to the ketone by ω-TA activityBack to article page
