CC -!- FUNCTION: Activation of anaerobic ribonucleoside-triphosphate reductase
CC under anaerobic conditions by generation of an organic free radical,
CC using S-adenosylmethionine and reduced flavodoxin as cosubstrates to
CC produce 5'-deoxy-adenosine. {ECO:0000256|ARBA:ARBA00003852,
CC ECO:0000256|PIRNR:PIRNR000368}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=glycyl-[protein] + reduced [flavodoxin] + S-adenosyl-L-
CC methionine = 5'-deoxyadenosine + glycin-2-yl radical-[protein] + H(+)
CC + L-methionine + semiquinone [flavodoxin]; Xref=Rhea:RHEA:61976,

CC ChEBI:CHEBI:57844, ChEBI:CHEBI:59789, ChEBI:CHEBI:140311;
CC Evidence={ECO:0000256|ARBA:ARBA00000544};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000256|ARBA:ARBA00001966};
CC -!- SIMILARITY: Belongs to the organic radical-activating enzymes family.
CC {ECO:0000256|ARBA:ARBA00009777, ECO:0000256|PIRNR:PIRNR000368}.
