DE Cytochrome c oxidase subunit I (EC 1.9.3.1) (Fragment). GN Name=COI; OS Cyclope pellucida. OG Mitochondrion. OC Eukaryota; Metazoa; Mollusca; Gastropoda; Orthogastropoda; OC Apogastropoda; Caenogastropoda; Sorbeoconcha; Hypsogastropoda; OC Neogastropoda; Buccinoidea; Nassariidae; Cyclope. OX NCBI_TaxID=407119; RN [1] RP NUCLEOTIDE SEQUENCE. RA Simon-Bouhet B., Garcia P., Viard F.; RT "The genus Cyclope: a mitochondrial marker to discriminate two RT species."; RL Submitted (SEP-2006) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Cytochrome c oxidase is the component of the respiratory CC chain that catalyzes the reduction of oxygen to water. Subunits 1- CC 3 form the functional core of the enzyme complex. CO I is the CC catalytic subunit of the enzyme. Electrons originating in CC cytochrome c are transferred via the copper A center of subunit 2 CC and heme A of subunit 1 to the bimetallic center formed by heme A3 CC and copper B (By similarity). CC -!- CATALYTIC ACTIVITY: 4 ferrocytochrome c + O(2) + 4 H(+) = 4 CC ferricytochrome c + 2 H(2)O. CC -!- PATHWAY: Respiratory chain; terminal step. CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane; Multi-pass CC membrane protein (By similarity). CC -!- SIMILARITY: Belongs to the heme-copper respiratory oxidase family.
