A metallochaperone complex consisting of nine subunits (COA3, COA5, COX10, dimeric COX11, COX15, COX16, COX19, SCO1, SCO2) carries two copper cations from the outer side of the inner mitochondrial membrane, where they were delivered by the copper chaperone COX17, to the pre-assembled MT-CO2 subunit. These copper ions are frequently called CuA (Nývltová et al., 2022; reviewed in Ruiz et al., 2021).
