CC -!- FUNCTION: Activation of pyruvate formate-lyase under anaerobic
CC conditions by generation of an organic free radical, using S-
CC adenosylmethionine and reduced flavodoxin as cosubstrates to produce
CC 5'-deoxy-adenosine. {ECO:0000256|RuleBase:RU362053}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=glycyl-[formate C-acetyltransferase] + reduced [flavodoxin] +
CC S-adenosyl-L-methionine = 5'-deoxyadenosine + glycin-2-yl radical-
CC [formate C-acetyltransferase] + H(+) + L-methionine + semiquinone
CC [flavodoxin]; Xref=Rhea:RHEA:19225, Rhea:RHEA-COMP:10622, Rhea:RHEA-
CC COMP:12190, Rhea:RHEA-COMP:12191, Rhea:RHEA-COMP:14480,

CC ChEBI:CHEBI:59789, ChEBI:CHEBI:140311; EC=1.97.1.4;
CC Evidence={ECO:0000256|RuleBase:RU362053};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000256|RuleBase:RU362053};
CC Note=Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3
CC cysteines and an exchangeable S-adenosyl-L-methionine.
CC {ECO:0000256|RuleBase:RU362053};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|RuleBase:RU362053}.
CC -!- SIMILARITY: Belongs to the organic radical-activating enzymes family.
CC {ECO:0000256|ARBA:ARBA00009777, ECO:0000256|RuleBase:RU362053}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
