UniProt functional annotation for P69902

UniProt code: P69902.

Organism: Escherichia coli (strain K12).
Taxonomy: Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia.
 
Function: Involved in the catabolism of oxalate and in the adapatation to low pH via the induction of the oxalate-dependent acid tolerance response (ATR). Catalyzes the transfer of the CoA moiety from formyl- CoA to oxalate. It can also use succinate as an acceptor. {ECO:0000269|PubMed:12844490, ECO:0000269|PubMed:18245280, ECO:0000269|PubMed:23335415}.
 
Catalytic activity: Reaction=formyl-CoA + oxalate = formate + oxalyl-CoA; Xref=Rhea:RHEA:16545, ChEBI:CHEBI:15740, ChEBI:CHEBI:30623, ChEBI:CHEBI:57376, ChEBI:CHEBI:57388; EC=2.8.3.16; Evidence={ECO:0000255|HAMAP-Rule:MF_00742, ECO:0000269|PubMed:18245280};
Biophysicochemical properties: Kinetic parameters: KM=180 uM for formyl-CoA (with succinate as acceptor at pH 6.7 and 30 degrees Celsius) {ECO:0000269|PubMed:18245280}; KM=352 uM for formyl-CoA (with oxalate as acceptor at pH 6.7 and 30 degrees Celsius) {ECO:0000269|PubMed:18245280}; KM=510 uM for oxalate (with formyl-CoA as donor at pH 6.7 and 30 degrees Celsius) {ECO:0000269|PubMed:18245280}; KM=80 mM for succinate (with formyl-CoA as donor at pH 6.7 and 30 degrees Celsius) {ECO:0000269|PubMed:18245280}; Note=Kcat is 130 sec(-1) for CoA-transferase activity with formyl-CoA as substrate (with oxalate as acceptor at pH 6.7 and 30 degrees Celsius). Kcat is 5.3 sec(-1) for CoA-transferase activity with formyl-CoA as substrate (with succinate as acceptor at pH 6.7 and 30 degrees Celsius).;
Pathway: Metabolic intermediate degradation; oxalate degradation; CO(2) and formate from oxalate: step 1/2. {ECO:0000255|HAMAP-Rule:MF_00742}.
Subunit: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00742, ECO:0000269|PubMed:12844490, ECO:0000269|PubMed:14993676}.
Induction: By the acid response regulator EvgA. {ECO:0000269|PubMed:12694615, ECO:0000269|PubMed:23335415}.
Disruption phenotype: Cells lacking this gene show a reduced acid tolerance response (ATR) during the adaptation phase. However the deletion of YfdW has no effect on survival in oxalate-containing challenge medium. {ECO:0000269|PubMed:23335415}.
Similarity: Belongs to the CoA-transferase III family. Frc subfamily. {ECO:0000255|HAMAP-Rule:MF_00742, ECO:0000305}.
