CRYSTAL STRUCTURE OF TYPE I CYTOCHROME C3 FROM DESULFOVIBRIO AFRICANUS
Overview
In Desulfovibrio metabolism, periplasmic hydrogen oxidation is coupled to, cytoplasmic sulfate reduction via transmembrane electron transfer, complexes. Type II tetraheme cytochrome c3 (TpII-c3), nine-heme cytochrome, c (9HcA) and 16-heme cytochrome c (HmcA) are periplasmic proteins, associated to these membrane-bound redox complexes and exhibit analogous, physiological function. Type I tetraheme cytochrome c3 (TpI-c3) is thought, to act as a mediator for electron transfer from hydrogenase to these, multihemic cytochromes. In the present work we have investigated, Desulfovibrio africanus (Da) and Desulfovibrio vulgaris Hildenborough, (DvH) TpI-c3/TpII-c3 complexes. Comparative kinetic experiments of Da, TpI-c3 and TpII-c3 using electrochemistry confirm that TpI-c3 is much more, efficient ... [(full description)]
