An objective of the present invention is to provide efficient methods for producing D-β-hydroxyamino acids (formula 2 or 4), such as D-erythro-2-amino-3-cyclohexyl-3-hydroxypropionic acid, which are useful as intermediates in the synthesis of pharmaceutical products and others.
The present invention makes it possible to efficiently produce D-erythro-2-amino-3-cyclohexyl-3-hydroxypropionic acid by cleaving unnecessary L-erythro-2-amino-3-cyclohexyl-3-hydroxypropionic acid in industrially feasible concentrations of DL-erythro-2-amino-3-cyclohexyl-3-hydroxypropionic acid used as starting material by using
Pseudomonas putida
-derived L-phenylserine aldolase.
本发明的一个目标是提供生产D-β-羟基氨基酸(公式2或4)的高效方法,例如D-erythro-2-amino-3-cyclohexyl-3-hydroxypropionic acid,这些中间体在合成药物产品和其他产品中有用。本发明通过使用由假单胞菌产生的L-苯丝氨醛酸醛缩酶,可以在工业可行的浓度下裂解不必要的L-erythro-2-amino-3-cyclohexyl-3-hydroxypropionic acid,从而有效生产D-erythro-2-amino-3-cyclohexyl-3-hydroxypropionic acid。
