ribulose phosphate -epimerase 中文意思是什麼
ribulose phosphate -epimerase
解釋
-
In these chloroplasts carbon dioxide combines with phosphoenolpyruvate to form oxaloacetic acid, which is transported to the bundle sheath cells, where the carbon dioxide is released, then fixed by the enzyme ribulose bisphosphate carboxylase to form glycerate 3 - phosphate, the first step in the calvin cycle
在葉肉細胞的葉綠體中二氧化碳與磷酸烯醇丙酮酸結合形成草酰乙酸，后被運到鄰近的維管束鞘細胞，在那裡二氧化碳被釋放，后被核酮糖二磷酸羧化酶固定形成3磷酸甘油酸，這是卡爾文的循環第一步。 -
Glycerate 3 - phosphate is the first product of the dark reactions of photosynthesis, formed by the carboxylation and cleavage of ribulose bisphosphate
甘油3 ?磷酸是光合作用暗反應的一種產物，在二磷酸核酮糖的羧化分解后形成。 -
Kinetic study shows that nadp + is the only valid coenzyme and that one substrate have no effect on the the other substrates " bind with the enzyme. products are competitive inhibitors, nadp + / nadph and 6 - phosphogluconate / ribulose - 5 - phosphate pairs are competitive whatever the concentration of the other substrates but noncompetitive versus the other substrates. therefore the kinetic mechanism of the 6 - phosphogluconate dehydrogenase is haldance - laidler - socquet random mechanism
兩種底物與酶的結合互不影響，而在產物抑制效果上， 5一磷酸核酮糖只競爭性抑制6一磷酸葡萄糖酸， nadph只競爭性抑制nadp + ，所以該酶催化機理是haidance一laidier一socquet隨機機理。
