pentose n.【化學】戊醣。

pentothal

E . coli is capable of metabolizing both hexose and pentose sugars , but it lacks pdc - adh ii system . however , , zymomonas mobilis is able to produce ethanol efficiently by an overactive pdc - adh ii system , but its utilizable substrate range is restricted to glucose and fructose 大腸桿菌含有同化戊糖和己糖的所有必需酶,但缺乏pdc - adh系統,只能生成非常少的酒精。相反,運動發酵單胞菌具有較強的pdc - adh系統,能很好地發酵生成酒精,但只能利用葡萄糖和果糖。

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。

Biochemistry ) a nitrogenous molecule , either a pyrimidine or a purine , that combines with a pentose sugar and phosphoric acid to form a nucleotide , the fundamental unit of nucleic acids 2堿基:一種含氮的分子,嘌呤堿或者是嘧啶堿,它們和戊糖還有磷酸一起構成核苷酸,核苷酸是核酸的基本結構單位。

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。

Deoxyribose a pentose ( five - carbon ) sugar that is a component of the nucleotides that make up dna 脫氧核糖:組成dna核苷的一種戊糖(五個碳) 。
