[ objective ] heparin is linear polysaccharides consisting of repeating disaccharide unit backbones of n - acetyl - d - glucosamine that is linked to d - glucuronic acid. the disaccharide repeat unit can be modified to include n - and o - sulfation ( 6 - o and 3 - o sulfation of the glucosamine and 2 - o sulfation of the uronic acid ). these specific sulfate patterns are involved in the interaction of heparin with other molecules
[目的]肝素是由n -乙酰葡萄糖胺與d -葡萄糖醛酸以1 4糖苷鍵連接起來的重復二糖單位組成的線性多糖，葡萄糖胺可帶有n -硫酸基團，可在c6上形成0 -硫酸酯，帶有硫酸基團的獨特結構參與了肝素與其他分子的相互作用。Studies of inactivation of a - transglucosidase by chemical modification demonstrated that cys, asp ( glu ) and his residues were indispensable groups of the a - transglucosidase. partial disulfide bonds were the function of this enzyme
因止，認為cys 、 asp （以）和川s殘基為q葡萄糖轉苦酶的必需基團，部分二硫鍵對保護酶的催化功能是必需的。The results showed that the structure of wheat straw was destroyed in liquefaction, with producing some ramification of glucose some screened strains can decompose and use the liquefaction products
結果表明，液化產物中出現甲基和亞甲基等基團的振動，並存在麥草纖維素的單體葡萄糖的衍生物，說明液化反應破壞了纖維類廢棄物的晶格結構。And some methods for improving their poor solubility are introduced, including : incorporating bulky groups, hydrophilic groups, water soluble polymers and hyper - branched dendrimers ; synthesizing branched derivatives ; and degrading them into oligosaccharide
對其解決的方法進行了分析總結：將體積較大的側基或親水性基團大分子引入到分子鏈上，支鏈化或鍵接超支化合物，以及低聚糖化，以滿足不同應用領域特別是生物醫學工程的要求。Chitosan - nylon composite membrane with two active group ( - nh2 and - oh ) had a hydrophilic surface and good blood compatibility, so it can be widely used in affinity separation
其中尼龍殼聚糖復合膜具有胺基和羥基兩種活性基團、良好的親水性能、較佳的血液和生物相容性，可廣泛應用於親和微濾。A. niger m - l which was screened in our laboratory produced a strongly a - transglucosidase. in this paper, studies on the fermentation conditions, purification and characterization of a - transglucosidase and its necessary groups was carried out in this dissertation. the main reports were as following : the fermentation conditions in shaking flasks were investigated by the method of single - factor analysis, the suitable main medium was achieved : which contained 4 % a, 2 % b and 1 % g ; the a. niger m - l was inoculated into 100ml medium in flask, shaking in 33 c at 140r / min for four days, with initial ph6. 5 and 6 % inocula volume ; adding 0. 1 mmol / l methyl a - d - glucopyranoside had inductive effect on enzyme formation, the a - transglucosidase activity amounted to 296. 05u / ml
本研究以黑麴黴m - 1為出發菌株，對其-葡萄糖轉苷酶的產酶影響因素、純化、酶學性質以及必需基團進行系統的研究，結果如下：通過對影響黑麴黴m - 1產-葡萄糖轉苷酶的單因素分析，得液態發酵生產-葡萄糖轉苷酶的最適產酶條件為： 4 a ， 2 b和1 g ；在33 ，起始ph值為6 . 5 ，轉速為140r min ，接種量為6 ，裝液量100ml條件下，發酵4 . 0d ，酶活力達296 . 05u ml ，添加0 . 1mmol l的酶作用底物甲基- - d -葡萄糖苷對產酶的誘導作用最大。分享友人
