HEXADECAHEME HIGH MOLECULAR WEIGHT CYTOCHROME HMC FROM DESULFOVIBRIO VULGARIS HILDENBOROUGH
OverviewOverview
Sulfate-reducing bacteria contain a variety of multi-heme c-type, cytochromes. The cytochrome of highest molecular weight (Hmc) contains 16, heme groups and is part of a transmembrane complex involved in the sulfate, respiration pathway. We present the 2.42 A resolution crystal structure of, the Desulfovibrio vulgaris Hildenborough cytochrome Hmc and a structural, model of the complex with its physiological electron transfer partner, cytochrome c(3), obtained by NMR restrained soft-docking calculations. The, Hmc is composed of three domains, which exist independently in different, sulfate-reducing species, namely cytochrome c(3), cytochrome c(7), and, Hcc. The complex involves the last heme at the C-terminal region of the, V-shaped Hmc and heme 4 of cytochrome c(3), and represents an example for, specific cytochrome-cytochrome interaction.
