摘要以呋喃甲醛為起始原料，經厲化、貝克曼重排、異氰脲酸化、氨基化、縮合和成鹽6步反應，合成了酰脲類青霉素抗生素呋布西林鈉。Synthesis of novel thioureas and thiosemicarbazides containing 1, 2, 3 - triazole
對甲氧基苯甲酰基氨基硫脲的合成與表徵Synthesis and biological activities of 2 - fluoro - 6 - chlorobenzoylpyrimidinylthioureas
含三嗪基二取代氨基甲酰脲的合成及其生物活性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。分享友人
