Abstract

Cytochrome c oxidase isolated from ox heart forms a complex in the presence of millimolar concentrations of CO with absorption bands at 606, 565 and 435 nm (difference spectrum), distinct from both ferrocytochrome a and the classical 590nm carbon-monoxyferrocytochrome a3. This species, which closely resembles Compound C, the derivative formed on photolysis and oxygenation of mixed-valence cytochrome a3+a32+CO, may represent a cytochrome a32+CO complex in which the associated ('invisible') copper is still oxidized.

摘要

从牛心分离出的细胞色素c氧化酶在毫摩尔浓度的一氧化碳存在下形成一种复合物,其在606、565和435纳米处有吸收带(差光谱),这与亚铁细胞色素a和经典的590纳米碳-一氧亚铁细胞色素a3均不同。该物种与化合物C非常相似,化合物C是混合价态细胞色素a3+a32+CO光解和氧化时形成的衍生物,它可能代表一种细胞色素a32+CO复合物,其中相关的(“不可见的”)铜仍处于氧化状态。
