The present invention relates to, for example, an α-substituted β-amino acid ester derivative asymmetric hydrolase including an enzyme of the following (a) or (b):
(a) an enzyme comprising the amino acid sequence of SEQ ID NO:1 at least from position 1 to position 362, wherein the tyrosine at position 277 of SEQ ID NO:1 is substituted with alanine, tryptophan, isoleucine, or histidine, and having the ability to hydrolyze a substrate; or
(b) an enzyme comprising the amino acid sequence of SEQ ID NO:1 at least from position 1 to position 362, wherein the tyrosine at position 277 of SEQ ID NO:1 is substituted with an amino acid other than tyrosine, and having the ability to hydrolyze a substrate.
本发明涉及例如一种α-取代的β-氨基酸酯衍生物不对称水解酶,包括下列(a)或(b)的酶:
(a) 包含至少从位置 1 到位置 362 的 SEQ ID NO:1 的氨基酸序列的酶,其中 SEQ ID NO:1 的位置 277 的酪氨酸被丙氨酸、色氨酸、异亮氨酸或组氨酸取代,并具有水解底物的能力;或
(b) 包含 SEQ ID NO:1 的氨基酸序列至少从位置 1 到位置 362 的酶,其中 SEQ ID NO:1 的位置 277 的酪氨酸被酪氨酸以外的氨基酸取代,并具有水解底物的能力。
