Abstract

The alpha-peak in the difference spectrum between reduced cytochrome c oxidase (cytochrome a and a3) plus acephate (pH 9.5) and oxidized enzyme, shifted from 605 nm to 592 nm. The difference spectrum between reduced cytochrome c oxidase plus acephate (pH 9.5) and the reduced enzyme showed that the alpha and gamma peaks shifted to 592 nm and 432 nm, respectively. The effect of acephate on the spectrum of the reduced cytochrome c oxidase is similar to that of carbon monoxide.

摘要

还原型细胞色素c氧化酶（细胞色素a和a3）加乙酰甲胺磷（pH 9.5）与氧化型酶之间的差光谱中的α峰，从605纳米移至592纳米。还原型细胞色素c氧化酶加乙酰甲胺磷（pH 9.5）与还原型酶之间的差光谱表明，α峰和γ峰分别移至592纳米和432纳米。乙酰甲胺磷对还原型细胞色素c氧化酶光谱的影响与一氧化碳相似。
