The present invention relates, in general, to an enzyme that degrades oxalic acid. In particular, the invention relates to the enzyme oxalate decarboxylase and to a DNA sequence encoding same. The invention further relates to a recombinant molecule comprising the oxalate decarboxylase encoding sequence and to a host cell transformed therewith. In addition, the invention relates to a method of protecting a plant from the deleterious effects of oxalic acid and to a method of reducing the oxalic acid content of a plant.
A human oxalyl-CoA decarboxylase polypeptide and DNA(RNA) encoding such polypeptide and a procedure for producing such polypeptide by recombinant techniques and for producing an antibody against such polypeptide are disclosed. Also disclosed is a combination of the polypeptide of the present invention and a suitable pharmaceutical carrier for providing a therapeutically effective amount of the polypeptide for the treatment of urolithiasis and hyperoxaluria. Also disclosed are assays for identifying mutations in nucleic acid sequence encoding a polypeptide of the present invention and for detecting altered levels of the polypeptide of the present invention.
