Xu, Tang et al. show that ω-transaminase CrmG is insensitive to the inhibition from by-products α-ketoglutarate or pyruvate. They find that these by-products cannot interact strongly with the flexible roof of the active site in CrmG. This study provides insights into the rational design of transaminase to eliminate by-product inhibition.
