protonation
解釋
n. 名詞 質子注入。-
Whole cell c2d2 reduction by all four mutants comparing to wild type and ni / v mutant was also detected. the result showed that only single a - gln194 substitution did not perturb the stereospecificity of protonation of c2d2. the above comparing results indicate that in mofe protein ( 1 ) a a - gln190 site and its association with homocitrate are important for the transfer of electron / proton to femoco, while a - his194 site and the homocitrate are independent in h2 evolution
對四個突變株細胞的c _ 2d _ 2還原特性及還原產物中反式-順式- 1 ， 2 -二氘代乙炔的比例進行了測定並與野生型及nifv突變株相比較，結果表明只有- gln ~ （ 194 ）替換不影響c _ 2d _ 2還原產物中反式-順式- 1 ， 2 -二氘代乙炔的比例，即未改變固氮酶還原c _ 2h _ 2加氫的立體構型的專一性。 -
By observing the effect of acidity on the uv difference spectra of ehpg or hbed, the spectral characteristics of apoovotransferrin binding to metals and anions at ph 7. 4 show that the reaction of apoovotransferrin with metals is related to deprotonation of the phenolic group of tyrosine of the metal binding sites, while the binding of apoovotransferrin to anions is associated with the protonation of the phenolic group of tyrosine of the anion binding sites
摘要通過觀察酸度對模擬轉鐵蛋白小分子ehpg和hbed紫外差光譜的影響，結合脫鐵伴清蛋白與金屬離子、陰離子結合的光譜特性，推斷脫鐵伴清蛋白與金屬離子的結合導致金屬離子結合位點處酪氨酸酚羥基的去質子化，而與陰離子的結合導致陰離子結合位點處酪氨酸酚羥基的質子化。
