Abstract
Oxidation-reduction midpoint potentials for the molybdenum center in assimilatory NADH:nitrate reductase isolated from spinach (Spinacia oleracea) have been determined at pH 7.0 in the presence of dye mediators using EPR spectroscopy to monitor formation of Mo(V). Values for the Mo(VI)/Mo(V) and Mo(V)/Mo(IV) couples were determined to be -8 and -42 mV, respectively.
摘要
利用电子顺磁共振波谱法监测钼（V）的形成，在pH 7.0且存在染料介质的条件下，测定了从菠菜（Spinacia oleracea）中分离出的同化型NADH：硝酸还原酶中钼中心的氧化还原中点电位。Mo（VI）/Mo（V）和Mo（V）/Mo（IV）电对的值分别测定为-8和-42 mV。
