Protein Machineries Involved in the Attachment of Heme to Cytochrome c: Protein Structures and Molecular Mechanisms
Table 1
Protein components of Systems I, II, and III along with their structural features (or PDB codes, when known) and functional roles. System I proteins are found in - and -proteobacteria, some - and -proteobacteria, and Deinococci and Archaea. Plant mitochondria. Mitochondria of some protozoa. System II proteins are found in plant chloroplasts. Gram-positive bacteria, cyanobacteria, -proteobacteria, most -proteobacteria, and some -proteobacteria. HCCS of System III is found in the mitochondria of fungi, vertebrates, and invertebrates.
