Title:
(S)-SELECTIVE HYPERACTIVE MUTANT ARYLMALONATE DECARBOXYLASE
Document Type and Number:
WIPO Patent Application WO/2012/117999
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a mutant arylmalonate decarboxylase of (S)-selective hyperactive form which is capable of producing (S)-α-arylpropionic acid with an optical purity of almost 100%e.e. from arylmalonic acid. The mutant arylmalonate decarboxylase of (S)-selective hyperactive form, which is capable of producing (S)-α-arylpropionic acid from arylmalonic acid, has mutation (i), mutations (i) and (ii), mutations (i) and (iii), or mutations (i), (ii) and (iii) in the amino acid sequence of wild-type arylmalonate decarboxylase that is represented by SEQ ID NO:2:
(i) substitution of glycine at 74 position by cysteine, and substitution of cysteine at 188 position by glycine;
(ii) substitution of tyrosine at 48 position by another amino acid; and
(iii) substitution of methionine at 159 position by another amino acid.
