Function[HMWC_DESVH] HMWC (high-molecular-weight cytochrome c), ORF2, ORF3, ORF4, ORF5 and ORF6 in the HMC operon form a transmembrane protein complex that allows electron flow from the periplasmic hydrogenase to the cytoplasmic enzymes that catalyze reduction of sulfates. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedSulfate-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. The crystal structure of the hexadeca-heme cytochrome Hmc and a structural model of its complex with cytochrome c(3).,Czjzek M, ElAntak L, Zamboni V, Morelli X, Dolla A, Guerlesquin F, Bruschi M Structure. 2002 Dec;10(12):1677-86.
