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).
