A, B [auth C]	PF13370	4Fe-4S single cluster domain of Ferredoxin I (Fer4_13)	4Fe-4S single cluster domain of Ferredoxin I	Fer4_13 is a ferredoxin I from sulfate-reducing bacteria. Chemical sequence analysis suggests that this characteristic [4Fe-4S] cluster sulfur environment is widely distributed among ferredoxins [1].	Domain
