A, B	PF04055	Radical SAM superfamily (Radical_SAM)	Radical SAM superfamily	Radical SAM proteins catalyse diverse reactions, including unusual methylations, isomerisation, sulphur insertion, ring formation, anaerobic oxidation and protein radical formation.	Domain
A, B	PF13353	4Fe-4S single cluster domain (Fer4_12)	4Fe-4S single cluster domain	This family includes proteins containing domains which bind to iron-sulfur clusters. Members include bacterial ferredoxins, various dehydrogenases, and various reductases. The structure of the domain is an alpha-antiparallel beta sandwich.	Domain
