==Best model of the electron transfer complex between cytochrome c3 and [Fe]-hydrogenase==
-
Cytochrome c(3) (M(r) 13000) is a low redox potential cytochrome specific, of the anaerobic metabolism in sulfate-reducing bacteria. This tetrahemic, cytochrome is an intermediate between the [Fe]-hydrogenase and the, cytochrome Hmc in Desulfovibrio vulgaris Hildenborough strain. The present, work describes the structural model of the cytochrome, c(3)-[Fe]-hydrogenase complex obtained by nuclear magnetic resonance, restrained docking. This model connects the distal cluster of the, [Fe]-hydrogenase to heme 4 of the cytochrome, the same heme found in the, interaction with cytochrome Hmc. This result gives evidence that, cytochrome c(3) is an electron shuttle between the periplasmic hydrogenase, and the Hmc membrane-bound complex.

[https://www.uniprot.org/uniprot/PHFL_NITV2 PHFL_NITV2] May be involved in hydrogen uptake for the reduction of sulfate to hydrogen sulfide in an electron transport chain. Cytochrome c3 is likely to be the physiological electron carrier for the enzyme.

Cytochrome c(3) (M(r) 13000) is a low redox potential cytochrome specific of the anaerobic metabolism in sulfate-reducing bacteria. This tetrahemic cytochrome is an intermediate between the [Fe]-hydrogenase and the cytochrome Hmc in Desulfovibrio vulgaris Hildenborough strain. The present work describes the structural model of the cytochrome c(3)-[Fe]-hydrogenase complex obtained by nuclear magnetic resonance restrained docking. This model connects the distal cluster of the [Fe]-hydrogenase to heme 4 of the cytochrome, the same heme found in the interaction with cytochrome Hmc. This result gives evidence that cytochrome c(3) is an electron shuttle between the periplasmic hydrogenase and the Hmc membrane-bound complex.
