The invention relates to transaminases and their use. The ATAs according to the invention are particularly useful for catalyzing the conversion of amines to ketones and/or vice versa. Preferably, the transaminase (ATA) according to the invention comprises an amino acid sequence with at least 80% homology to SEQ ID NO:1, wherein the amino acid sequence is engineered compared to SEQ ID NO:1 such that it comprises at least a substitution selected from the group consisting of F255L,F255A, F255C, F255D, F255E, F255G, F255H, F255K, F255M, F255N, F255P, F255Q, F255R, F255S, F255T, F255V, F255W, and F255Y. |
