乙内酰脲酶 meaning in English
hydantoinase
Examples
- Puc18 - 169 was a subcloned plasmid containing the whole operon sequence of l - hydantoinase from arthrobacter bt801 which can convert 5 - benzylhydantoin to l - phenylalanine . hydantoin hydrolase which is responsible for the ring opening of hydantoin is one of the components of hydantoin utility enzymes of arthrobacter bt801 . n - carbamoylase is a part of hydantoinase operon which can transform n - carbamoylamino acids into the corresponding amino acids
节杆菌( arthrobacter ) bt801是由军事医学科学院生物工程研究所保存的l -乙内酰脲酶产酶菌株， puc18 - 169是由本室构建的含有节杆菌bt801的l -乙内酰脲酶完整操纵子序列的亚克隆质粒。 - Hydantoinases which consist of hydantoin hydrolase , n - carbamoylase and sometimes hydantoin racemase can hydrolyze d , l - 5 - substituted hydantoin into corresponding optically active amino acids . therefore , the hydantoinases from micro - organisms are widely applied to the industrial production of natural and unnatural amino acids . microbial hydantoinases are considered as industrial enzymes from the origin of life
乙内酰脲酶是广泛存在于动物、植物和微生物的一类酶系，包括乙内酰脲水解酶( hydantoinhydrolase ， hyuh )和n -氨甲酰基氨基酸水解酶( n - carbamoylase ， hyuc ) ，有些情况下还包括乙内酰脲消旋酶( hydantoinracemase ， hyur ) 。 - The l - n - carbamoylase of arthrobacter bt801 , coded by the hyuc gene , is the rate - limiting and the only stereoselective enzyme . hydantoin hydrolase gene ( hyuh ) and n - carbamoylase gene ( hyu c ) were amplified from the plasmid of puc18 - 169 by pcr and , at the same time , activity expression was obtained in e . coli and pichia pastor is gs115 respectively
节杆菌bt801的乙内酰脲水解酶催化乙内酰脲类化合物水解开环， n -氨甲酰基氨基酸水解酶是该菌乙内酰脲酶系中惟一具有立体选择性的酶，也是整个反应体系的限速酶。
