关于 COX5B

功能概要

细胞色素 C 氧化酶 (COX) 是线粒体呼吸链的末端酶。它是一种多亚基酶复合物，可将电子从细胞色素 c 转移到分子氧，并促进穿过线粒体内膜的质子电化学梯度。该复合体由 13 个线粒体和核编码的亚基组成。线粒体编码的亚基执行电子转移和质子泵送活动。核编码亚基的功能未知，但它们可能在复合体的调节和组装中发挥作用。该基因编码人线粒体呼吸链酶的核编码亚基 Vb。[RefSeq 提供，2008 年 7 月]

Cytochrome C oxidase (COX) is the terminal enzyme of the mitochondrial respiratory chain. It is a multi-subunit enzyme complex that couples the transfer of electrons from cytochrome c to molecular oxygen and contributes to a proton electrochemical gradient across the inner mitochondrial membrane. The complex consists of 13 mitochondrial- and nuclear-encoded subunits. The mitochondrially-encoded subunits perform the electron transfer and proton pumping activities. The functions of the nuclear-encoded subunits are unknown but they may play a role in the regulation and assembly of the complex. This gene encodes the nuclear-encoded subunit Vb of the human mitochondrial respiratory chain enzyme. [provided by RefSeq, Jul 2008]
