It is an object of the present invention to provide a novel hydrolase, which is used when dialkyl 2-vinylcyclopropane-1,1-dicarboxylate is hydrolyzed with an enzyme, so as to efficiently obtain (1S,2S)-1-alkoxycarbonyl-2-vinylcyclopropanecarboxylic acid that is useful as an intermediate for synthesizing therapeutic agents for hepatitis C. According to the present invention, there is provided a hydrolase protein, which consists of the amino acid sequence shown in any one of SEQ ID NOS. 2 to 5 and which has activity of catalyzing, at higher selectivity than the protein consisting of the amino acid sequence shown in SEQ ID NO. 1, a reaction of producing (1S,2S)-1-ethoxycarbonyl-2-vinylcyclopropanecarboxylic acid from diethyl 2-vinylcyclopropane-1,1-dicarboxylate.
本发明的目的是提供一种新型的水解酶,当用酶水解二烷基2-乙烯基环丙烷-1,1-二甲酸酯时,可高效地获得(1S,2S)-1-烷氧羰基-2-乙烯基环丙烷羧酸,该化合物是合成治疗丙型肝炎药物的中间体。根据本发明,提供了一种水解酶蛋白,其由SEQ ID NO. 2到5中任一序列所示的氨基酸序列组成,具有在比SEQ ID NO. 1中所示的氨基酸序列组成的蛋白质更高的选择性催化反应,从二乙酸2-乙烯基环丙烷-1,1-二甲酸酯中产生(1S,2S)-1-乙氧羰基-2-乙烯基环丙烷羧酸。
