Two separate ornithine transcarbamylase enzymes have been found in extracts of late exponentialphase cells of Bacillus licheniformis grown on glucose and L-arginine. One enzyme presumably has a biosynthetic function and is repressed by arginine. The other is induced by arginine, is relatively heat-stable, and can be separated from the first by diethylaminoethyl chromatography.
