Cytochrome c biogenesis
WebThe deduced 106-amino acid human CMC1 protein contains 4 conserved cysteines in twin Cx (9)C motifs that are predicted to coordinate copper. Epitope-tagged CMC1 colocalized with COX subunit 1 (MTCO1; 516030) in a typical mitochondrial network pattern. In yeast, Cmc1 localized to the mitochondrial intermembrane space. WebSep 1, 2009 · Working models for cytochrome c biogenesis by systems I, II, and III. Models include trafficking and oxidation states of heme, as well as the subpathways for apocytochrome reduction (in red for system I and system II). Representative genera possessing each system are listed under the models.
