CC   -!- FUNCTION: Involved in the catabolism of oxalate and in the adapatation
CC       to low pH via the induction of the oxalate-dependent acid tolerance
CC       response (ATR). Catalyzes the transfer of the CoA moiety from formyl-
CC       CoA to oxalate (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=formyl-CoA + oxalate = oxalyl-CoA + formate;
CC         Xref=Rhea:RHEA:16545, ChEBI:CHEBI:15740, ChEBI:CHEBI:30623,
CC         ChEBI:CHEBI:57376, ChEBI:CHEBI:57388; EC=2.8.3.16;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00742};
CC   -!- PATHWAY: Metabolic intermediate degradation; oxalate degradation; CO(2)
CC       and formate from oxalate: step 1/2. {ECO:0000255|HAMAP-Rule:MF_00742}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00742}.
CC   -!- SIMILARITY: Belongs to the CoA-transferase III family. Frc subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_00742}.
