competitive inhibitor meaning in English
竞争性抑制剂，竞争性抑制物
竞争性抑制物
Examples
- A competitive inhibitor is usually structurally similar to the substrate , e . g . malonate is a competitive inhibitor of the enzyme succinate dehydrogenase
与底物结构相似的物质能竞争性的与酶结合，从而使酶不能与底物结合而丧失其催化活性。 - Additionally , protein bands were found in the range of 62 kd in microsomes from oryza sativa and 45 kd from arabidopsis thaliana - , 2 ) the ipar - like protein was mainly localized in the vacuolar membrane ( tonoplast ) and plasma membrane in the leaf and root tip of arabidopsis thaliana for confirming the biological role of the ip3r - like protein , we investigated the effects of methyl viologen ( stimulating ip3 produce ) and heparin ( a competitive inhibitor of inositol 1 , 4 , 5 - triphophate in animal ) on stomatal movement by epidermal strip bioassay . when the epidermal strips of arabidopsis thaliana were treated with methyl viologen , it stimulates the stomatal closure
拟南芥表皮条用甲基紫精处理，可以引起气孔的关闭，当处理90分钟的时候，气孔的相对开度由100降到58 ，统计学分析气孔开度的变化有显著差异；甲基紫精引起气孔关闭的作用可以被肝素部分抑制，当甲基紫精和肝素同时处理90分钟的时候，气孔的相对开度由100降到92 ，统计学分析气孔开度的变化没有显著差异，说明气孔的相对开度基本上没有变化。 - 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
两种底物与酶的结合互不影响，而在产物抑制效果上， 5一磷酸核酮糖只竞争性抑制6一磷酸葡萄糖酸， nadph只竞争性抑制nadp + ，所以该酶催化机理是haidance一laidier一socquet随机机理。
