Forward reaction of the external aldimine intermediate occurs by deprotonation of the substrate C-H bond, which is considered to be chemically the most difficult step in the reaction when referenced to model reactions in solution.[3842] The free base form of Lys258 acts as a general base catalyst for deprotonation, which has been shown experimentally by mutant enzymes and their rescue with exogenously added amine catalysts.[4345] Although the central 1,3-proton transfer between C of the substrate and C4 of the coenzyme could, in principle, occur via a concerted mechanism with Lys258 both deprotonating C and protonating C4 in the same transition state, the evidence weighs in favor of a stepwise mechanism with an intervening carbanionic intermediate
