The present disclosure relates to a method for preparing an optically active amino acid using cosubstrate shuttling of transaminase. The method includes coupling a reaction of converting a keto acid to an amino acid by α-transaminase and a reaction of transferring an amino group of an amine substrate by ω-transaminase (TA) using an amino acid cosubstrate. The present disclosure allows production of various optically active amino acids with high purity and high efficiency by solving the low equilibrium constant problem of transaminase and is applicable to production of various optically active amino acids in industrial scale. Since the present disclosure allows easy production of various unnatural amino acids having high reactivity and stability, which are used as pharmaceutical precursors, it can be usefully employed in preparation of pharmaceuticals, food additives and various animal feeds.
