Protein

Formyl-CoA:oxalate CoA-transferase

Gene

frc

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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.3 Publications

Catalytic activityi

Formyl-CoA + oxalate = formate + oxalyl-CoA.UniRule annotation1 Publication

Kineticsi

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).

    Pathwayi: oxalate degradation

    This protein is involved in step 1 of the subpathway that synthesizes CO(2) and formate from oxalate.UniRule annotation
    Proteins known to be involved in the 2 steps of the subpathway in this organism are:
    1. Formyl-CoA:oxalate CoA-transferase (frc)
    2. Oxalyl-CoA decarboxylase (oxc)
    This subpathway is part of the pathway oxalate degradation, which is itself part of Metabolic intermediate degradation.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes CO(2) and formate from oxalate, the pathway oxalate degradation and in Metabolic intermediate degradation.

    Pathology & Biotechi

    Disruption phenotypei

    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.1 Publication
