轉酮醇酶 的英文怎麼說
中文拼音 [zhuǎntóngchún]
轉酮醇酶
英文
transdetolase-
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 enzyme 5 - enolpyuvyl - 3 - phosphoshikimic acid synthase ( epsp synthase ; ec2. 5. 1. 19 ), encoded by anoa locus, is a key enzyme present in microorganisms and plants where it has a function in the biosynthesis of aromatic amino acids. glyphosate ( n - phosphonomethyl - glycine ) is an effective non - selective, broad spectrum, postemergence herbicide, which has been shown to inhibit epsp synthase activity in a competitive manner. glyphosate tolerant plants can be mediated by either overproduction of the target enzyme or by the presence of an altered enzyme
植物和微生物芳香族氨基酸生物合成過程中的一個關鍵酶? ? 5 -烯醇丙酮莽草酸- 3 -磷酸合成酶（ epspsynthase ； ec2 . 5 . 1 . 19 ）由aroa基因編碼，該酶受廣譜滅生性、內吸傳導型除草劑草甘膦的競爭性抑制，將epsp合成酶基因轉入植物中可獲得草甘膦耐受植株。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。That shows there are some difference in the steroid regulation between the anuras and the urodeles. among three of the steroid, one can convert to the other, and some enzyme activity is concerned with the conversion
三種類固醇激素存在相互轉化的關系，睪酮可能在雌二醇和孕酮的轉化中起著底物的作用，這種轉化與某種芳香化酶的活性有關。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。The rat 20a - hydroxysteroid dehydrogenase ( 20ahsd ) belongs to a family member of aldo - ketoreductases used nadph as a cofactor and principally converts progesterone to 20a - hydroxyprogesterone as a lower or non - active hormone. thus 20ohsd acts as a molecular switch and makes the potent progesterone hormone into an inactive potent metabolite
大鼠20 -羥類固醇脫氫酶（ 20 - hydroxysteroiddehydrogenase ， 20 hsd ）屬于醛酮氧化還原酶系成員，在大鼠卵巢中以nadph為輔酶將孕酮轉變為低或無活性的20 -羥孕酮。It presented a natural target because aromatase converts testosterone into estradiol, a potent form of estrogen also used in hormone replacement therapy
由於芳香酶能把睪酮轉化為雌二醇，而雌二醇也是一種能用於激素替代療法的雌激素，它就提供了一個天然的靶點。分享友人
