青霉素酰化酶在甲基丙烯酸縮水甘油酯共聚物上的固定化This approach includes lifestyle modifications, such as dietary changes and smoking cessation and the use of hmg - coa reductase inhibitors ( statins ), which are able to correct the lipid status and to prevent major cardiovascular events independently of the baseline lipidaemic or cardiovascular status
這些方法包括生活方式的改變，如飲食改變，戒煙以及運用-羥- -甲基戊二酸單酰輔酶a還原酶抑制劑（他汀類藥物） ，從而糾正脂類情況和預防非依賴性膽固醇血癥的主要心血管事件或心血管狀態。Resistance would be developed when the activities of any of these three enzymes are increased. the three insecticide target - sites are acetylcholinesterase ( ache ) for organophosphate and carbamate insecticides, voltage - gated sodium channels : knockdown resistance ( kdr or kdr - type ) for ddt & pyrethroids and y - aminobutyric acid ( gaba ) receptors for cyclodienes
殺蟲劑的作用靶標主要有：有機磷和氨基甲酸酯殺蟲劑的作用靶標?乙酰膽堿酯酶； ddt和擬除蟲菊酯類殺蟲劑的作用靶標?神經軸突鈉離子通道；環戊二烯類和吡唑類等殺蟲劑的作用靶標? -氨基丁酸（ gaba ）受體-氯離子通道復合體。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。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
乙內酰脲酶是廣泛存在於動物、植物和微生物的一類酶系，包括乙內酰脲水解酶（ hydantoinhydrolase ， hyuh ）和n -氨甲酰基氨基酸水解酶（ n - carbamoylase ， hyuc ） ，有些情況下還包括乙內酰脲消旋酶（ 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
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。To improve the production and activity of the enzyme, the hydantoin hydrolase gene ( hyuh ) was cloned into e. coli m15 and bl21 ( de3 ) by using vector pqe60 and pt221 respectively. two expression plasmids were thus constructed
用pcr技術從質粒puc18 - 169中擴增出l -乙內酰脲水解酶基因（ hyuh ）和n -氨甲酰基氨基酸水解酶基因（ hyuc ） ，分別在大腸桿菌和畢赤酵母中實現了活性表達。As far as the enzymatic activity is concerned, on the one hand, strain yz - ii6 has higher d - hydantoinase activity and lower d - carbamoylase activity so as not to be suitable for one - step bioconversion of d - amino acids, on the other hand, the higher hydantoinase activity, engineered strain in particular, may be convenient to be as a biocatalyst to produce n - carbamyl d - amino acids which hard to find in the markets
Yz - 6菌具有較高的海因酶活性，但n -氨甲酰基d -氨基酸酰氨水解酶活性很低，仍不適合用於d -型氨基酸生產工藝中的一步法轉化。另一方面，含海因酶基因的人工菌株不但酶活性高，也排除了天然菌株轉化生產d -型氨基酸過程中的一些副產物。分享友人
