Ornithine racemase has been purified to homogeneity from Clostridium sticklandii, as shown by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. This is the first racemase known to be highly specific to ornithine. This PLP-dependent enzyme has an M(r) of 92,000, with a K(m) for l-ornithine of 0.77 ± 0.05 mM and a k(cat) of 980 ± 20 s(−1).
