Supplementary information

MTCO1 also known as COX1 or MT-CO1 is an important component of the mitochondrial respiratory chain’s complex IV commonly called cytochrome c oxidase. This target is encoded by mitochondrial DNA and contributes to the complex's catalytic core. It is a transmembrane protein with a noted molecular weight of approximately 57 kDa. MTCO1 is predominantly expressed in tissues with high energy demand such as cardiac and skeletal muscles due to their reliance on efficient oxidative phosphorylation.

Biological function summary

MTCO1 is vital for the final step of the electron transport chain catalyzing the transfer of electrons from cytochrome c to oxygen. This process facilitates the reduction of oxygen molecules to water. MTCO1 is an integral part of cytochrome c oxidase a multi-subunit enzyme complex important for cellular energy production. Proper function of MTCO1 supports ATP synthesis by maintaining electrochemical gradients across the mitochondrial inner membrane.

Pathways

Electrons transfer through this protein is essential for effective oxidative phosphorylation and maintaining the proton gradient necessary for ATP synthesis. MTCO1 operates in tandem with proteins like COX2 within the electron transport chain to achieve optimal energy conversion and cellular respiration. The pathway interactions of MTCO1 are critical in efficiently powering cellular activities and upholding metabolic functions throughout the body.

Mutations or defects in MTCO1 have associations with various mitochondrial diseases such as Leber's Hereditary Optic Neuropathy (LHON) and mitochondrial complex IV deficiency. MTCO1 anomalies may disrupt normal function leading to impaired oxidative phosphorylation and energy deficits in cells. In LHON affected individuals can also demonstrate deficits linked to mutations in other mitochondrial genes like ND1 which further disrupt cellular energy balance and contribute to the clinical manifestations of these mitochondrial disorders.

Target data

Component of the cytochrome c oxidase, the last enzyme in the mitochondrial electron transport chain which drives oxidative phosphorylation. The respiratory chain contains 3 multisubunit complexes succinate dehydrogenase (complex II, CII), ubiquinol-cytochrome c oxidoreductase (cytochrome b-c1 complex, complex III, CIII) and cytochrome c oxidase (complex IV, CIV), that cooperate to transfer electrons derived from NADH and succinate to molecular oxygen, creating an electrochemical gradient over the inner membrane that drives transmembrane transport and the ATP synthase. Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. Electrons originating from reduced cytochrome c in the intermembrane space (IMS) are transferred via the dinuclear copper A center (CU(A)) of subunit 2 and heme A of subunit 1 to the active site in subunit 1, a binuclear center (BNC) formed by heme A3 and copper B (CU(B)). The BNC reduces molecular oxygen to 2 water molecules using 4 electrons from cytochrome c in the IMS and 4 protons from the mitochondrial matrix.
