Kinetic and mechanistic characterization of the formyl-CoA transferase from Oxalobacter formigenes.
S.Jonsson, S.Ricagno, Y.Lindqvist, N.G.Richards.
Oxalobacter formigenes is an obligate anaerobe that colonizes the human gastrointestinal tract and employs oxalate breakdown to generate ATP in a novel process involving the interplay of two coupled enzymes and a membrane-bound oxalate:formate antiporter. Formyl-CoA transferase is a critical enzyme in oxalate-dependent ATP synthesis and is the first Class III CoA-transferase for which a high resolution, three-dimensional structure has been determined (Ricagno, S., Jonsson, S., Richards, N., and Lindqvist, Y. (2003) EMBO J. 22, 3210-3219). We now report the first detailed kinetic characterizations of recombinant, wild type formyl-CoA transferase and a number of site-specific mutants, which suggest that catalysis proceeds via a series of anhydride intermediates. Further evidence for this mechanistic proposal is provided by the x-ray crystallographic observation of an acylenzyme intermediate that is formed when formyl-CoA transferase is incubated with oxalyl-CoA. The catalytic mechanism of formyl-CoA transferase is therefore established and is almost certainly employed by all other members of the Class III CoA-transferase family.

FIG. 7. The active site in FRC-oxalyl-CoA complex, monomer B. A, divergent eyes stereo view showing the interactions of the oxalylaspartyl anhydride with residues in the FRC dimer. The letter designation (A or B) in the numbering scheme indicates the FRC monomer in which the residue is located. This image was generated using VMD (58) and POV-Ray (Persistence of Vision Development Team). B, initial difference Fourier electron density map at 2.5 of the oxalyl-aspartyl anhydride. This image was generated using MOLSCRIPT (59) and Raster-3D (60).

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
