Abstract
A method for racemizing with N-acylamino acid racemase (NAAR) derived from and a method for producing optically active amino acids using the racemaization method are provided. The racemase of the present invention can efficiently catalyze the racemization of acylamino acid substrates including N-acylalanine, N-acylaspartic acid, N-acylleucine, and N-acylvaline. Furthermore, this method can be applied to efficient production of optically active amino acids, which are useful, for example, as medicinal raw materials.
