ω-Transaminase from Ochrobactrum anthropi is devoid of substrate and product inhibitions

Abstract

ω-Transaminases display complicated inhibitions by ketone products and both enantiomers of amine substrates. Here, we report the first example of ω-transaminase devoid of such inhibitions. Owing to the lack of enzyme inhibitions, the ω-transaminase from Ochrobactrum anthropi enabled efficient kinetic resolution of α-methylbenzylamine (500 mM) even without product removal. © 2013, American Society for Microbiology.
