甲基化酶類
英文
rna methylases-
The transfermants with highest resistance to g418 ( 4 g / l in ypd ) were screened to study their expression level in 150 ml shaking flask. having been induced with methanol for 36 hours, the target enzyme could be examined in the supernatant by measuring amidolytic activity
首次將大連蛇島賅蛇毒類凝血酶成熟基回克隆到表達載體ppicgk中，經電激轉化至畢氏酵母菌株gs15中，再經甲醇誘導，在150ml搖瓶畔1獲得細胞外分泌表達產物。In bioconversion of a d - amino acid and its derivative, the substrate, 5 ' - monosubstituted hydantoin is firstly transferred into an intermediate, d - carbamyl amino acid by d - hydantoinase, and in turn into an optically active d - amino acid by either d - carbamoylase or chemical, nano2. nowadays, the bioconversion of d - amino acids has been industrialized by enzymes, so called one - step process
D -型氨基酸及其衍生物的生物轉化，經歷兩個反應歷程，首先是在海因酶的作用下，催化5 -單替代海因形成氨甲酰類氨基酸中間物，後者再在酶或化學的作用下，生成相應的光學活性氨基酸或其衍生物。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
節桿菌bt801的乙內酰脲水解酶催化乙內酰脲類化合物水解開環， n -氨甲酰基氨基酸水解酶是該菌乙內酰脲酶系中惟一具有立體選擇性的酶，也是整個反應體系的限速酶。
