    Abstract

    A novel S-enantioselective amidase acting on 3,3,3-trifluoro-2-hydroxy-2-methylpropanamide was purified from Arthrobacter sp. S-2. The enzyme acted S-enantioselectively on 3,3,3-trifluoro-2-hydroxy-2-methylpropanamide to yield (S)-3,3,3-trifluoro-2-hydroxy-2-methylpropanoic acid. Based on the N-terminal amino acid sequence of this amidase, the gene coding S-amidase was cloned from the genomic DNA of Arthrobacter sp. S-2 and expressed in an Escherichia coli host. The recombinant S-amidase was purified and characterized. Furthermore, the purified recombinant S-amidase with the C-His6-tag, which was expressed in E. coli as the C-His6-tag fusion protein, was used in the kinetic resolution of (±)-3,3,3-trifluoro-2-hydroxy-2-methylpropanamide to obtain (S)-3,3,3-trifluoro-2-hydroxy-2-methylpropanoic acid and (R)-3,3,3-trifluoro-2-hydroxy-2-methylpropanamide.

    摘要

    从Arthrobacter sp. S-2中纯化出一种新型的S-对映选择性酰胺酶,可作用于3,3,3-三氟-2-羟基-2-甲基丙酰胺,选择性地将其转化为(S)-3,3,3-三氟-2-羟基-2-甲基丙酸。根据该酰胺酶的N末端氨基酸序列,从Arthrobacter sp. S-2的基因组DNA中克隆了编码S-酰胺酶的基因,并在Escherichia coli宿主中表达。纯化和表征了重组S-酰胺酶。此外,将在E. coli中表达为C-His6标签融合蛋白的纯化重组S-酰胺酶用于(±)-3,3,3-三氟-2-羟基-2-甲基丙酰胺的动力学分辨,获得(S)-3,3,3-三氟-2-羟基-2-甲基丙酸和(R)-3,3,3-三氟-2-羟基-2-甲基丙酰胺。
