By using a synthetic deoxyoligonucleotide probe designed to recognize the structural gene for cytochrome cc3 from Desulfovibrio vulgaris Hildenborough, a 3.7-kb XhoI genomic DNA fragment containing the cc3 gene was isolated. The gene encodes a precursor polypeptide of 58.9 kDa, with an NH2-terminal signal sequence of 31 residues. The mature polypeptide (55.7 kDa) has 16 heme binding sites of the form C-X-X-C-H. Covalent binding of heme to these 16 sites gives a holoprotein of 65.5 kDa with prope ...[more]
