轉酮糖酶 的英文怎麼說
中文拼音 [zhuǎntóngtáng]
轉酮糖酶
英文
transketolase-
Transketolase is the key enzyme of pentose - phophate pathway, catalyses transfer of a two - carbon fragment from a ketolase ( donor substance ) to an aldose ( acceptor substance )
摘要轉酮醇酶是磷酸戊糖途徑的關鍵酶，催化二碳單元在酮糖（供體）和醛糖（受體）間的轉移。The 11 - hsd1 expression in the fetal brain also gradually increases with gestational age at late gestation and continues to increase in the hippocampus after birth until the 15th postnatal day, which shows a pattern very similar to th secretion. furthermore, previous data show injection of thyroxine ( t4 ) to normal newborn rats up - regulates gr expression in the hippocampus. these data suggest that the role of th in neural development may be partially ( if not all ) accomplished through regulating gc ' s activity
在海馬結構， 11 - hsd1與gr共存於同一海馬神經元內，主要呈現還原酶的特性，能使無活性的11 -脫氫皮質酮（ a ）可的松（ e ）轉化為有活性的皮質酮（ b ）皮質醇（ f ） ，從而提高組織局部的糖皮質激素濃度，這樣， 11 - hsd1的存在就為親和力較低的gr發揮作用提供了前提條件。The a - transglucosidase was selectively modified by pcmb, me, edc, clac, acetyl acetone and nbs, and changes in the activities of the enzyme have been detected. the reaction of a - transglucosidase with pcmb, me, edc and clac resulted in a strong inhibition of the enzyme activities which decreased with the increase of modifier concentration. the acetyl acetone and nbs were found without inhibition effect
酚丙酮、小涅代唬拍酷亞胺剛b引等化學修飾劑對a葡萄糖轉苦酶的幾種氨基酸殘基進行選擇修飾，並測定其酶活力變化，結果表明： pcmb 、 me 、 edc 、 ciac能顯著抑制酶的活性，活力的下降與修飾劑的濃度有關，乙酚丙酮、 nbs白巾飾對酶的奪製作用不明顯。Ppsa and tkta are the key genes in central metabolism of aromatic amino acids biosynthesis. ppsa encoding phosphoenolpyrucate synthetase a ( ppsa ) which catalyzes pyruvate into pep ; tkta encoding transketolase a which plays a major role in erythrose - 4 - phosphate ( e4p ) production of pentose pathway
Ppsa基因編碼磷酸烯醇式丙酮酸合成酶a （ ppsa ） ，該酶催化丙酮酸合成磷酸烯醇式丙酮酸； tkta基因編碼轉酮酶a ，該酶在磷酸戊糖途徑中生成4 -磷酸赤蘚糖起主要作用。分享友人
