Function[FCTA_OXAFO] Catalyzes the transfer of the CoA moiety from formyl-CoA to oxalate. Essential enzyme for the bacterium survival, as it relies on oxalic acid as its sole source of energy.[HAMAP-Rule:MF_00742] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedFormyl-CoA transferase catalyses transfer of CoA from formate to oxalate in the first step of oxalate degradation by Oxalobacter formigenes, a bacterium present in the intestinal flora which is implicated in oxalate catabolism in mammals. Formyl-CoA transferase is a member of a family of CoA-transferases for which no structural information is available. We now report the three-dimensional structure of O.formigenes formyl-CoA transferase, which reveals a novel fold and a very striking assembly of the homodimer. The subunit is composed of a large and a small domain where residues from both the N- and C-termini of the subunit are part of the large domain. The linkers between the domains give the subunit a circular shape with a hole in the middle. The enzyme monomers are tightly interacting and are interlocked. This fold requires drastic rearrangement of approximately 75 residues at the C-terminus for formation of the dimer. The structure of a complex of formyl-CoA transferase with CoA is also reported and sets the scene for a mechanistic understanding of enzymes of this family of CoA-transferases. Formyl-CoA transferase encloses the CoA binding site at the interface of an interlocked dimer.,Ricagno S, Jonsson S, Richards N, Lindqvist Y EMBO J. 2003 Jul 1;22(13):3210-9.
