Type: | Family | Name: | 3Fe-4S ferredoxin |
Description: | In a few bacterial P450-containing systems, the transfer of electrons from flavoprotein reductase to P450 is mediated by 3Fe-4S ferredoxins [, , ]. Despite functional similarity of such ferredoxins tothe adrenodoxin family, they do not share sequence similarity but seem to be similar to some mono-[4Fe-4S]cluster ferredoxins but lack the fourth cysteine residue conserved in 4Fe-4S sequences []. It has been shownexperimentally that the 4Fe-4S cluster of related ferredoxins from archaebacteria easily converts to a 3Fe-4S cluster []. | Short Name: | 3Fe4S_ferredoxin |
