Subunit composition of
formyl-CoA transferase = [Frc]2
formyl-CoA transferase monomer = Frc
YfdW (Frc) is a formyl-CoA transferase with sequence and structural similarity to Frc from Oxalobacter formigenes, a strictly anaerobic bacterium found in the mammalian gut [Gruez03, Toyota08]. Unlike the O. formigenes enzyme, the E. coli enzyme shows high substrate specificity [Toyota08].
Crystal structures of apo-YfdW and YfdW with CoA, acetyl-CoA, or both acetyl-CoA and oxalate have been solved. YfdW is a homodimer; the ring-shaped monomers are concatenated like links of a chain [Gruez03, Gogos04].
The enzymatic reaction mechanism is predicted by structural similarity to related enzymes; residue D169 is predicted to catalyze the reaction [Gruez03]. Biochemical data indicates that the kinetic mechanism is ordered bi-bi sequential [Toyota08].
Frc is required during the adaption phase of an oxalate-induced acid tolerance response [Fontenot13]. Expression of frc is increased when the EvgAS two-component regulatory system is overexpressed [Masuda02].
