CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=acetyl-CoA + formate = CoA + pyruvate; Xref=Rhea:RHEA:11844,
CC         ChEBI:CHEBI:15361, ChEBI:CHEBI:15740, ChEBI:CHEBI:57287,
CC         ChEBI:CHEBI:57288; EC=2.3.1.54;
CC   -!- PATHWAY: Fermentation; pyruvate fermentation; formate from pyruvate:
CC       step 1/1.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- MISCELLANEOUS: Several mechanisms have been proposed based on complexes
CC       formed with substrate analogs. After activation by the glycine radical,
CC       the cysteine radical, Cys-417, can abstract hydrogen atoms from the
CC       other active site cysteine, Cys-416, and from coenzyme A, and it can
CC       also transfer hydrogen atoms to product radicals. The other active site
CC       cysteine can attack the central carbonyl of pyruvate and covalently
CC       bind the product acetyl group (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the glycyl radical enzyme (GRE) family. PFL
CC       subfamily. {ECO:0000305}.
