Pyrimidine biosynthesis in Neisseria meningitidis. 2. Regulation of enzyme synthesis
Abstract:
In Neisseria meningitidis aspartate carbamoyltransferase (ACTase), ornithine carbamoyltransferase (OCTase), and carbamoylphosphate synthetase (CPSase) showed incomplete repression by uracil and arginine. De-repression studies with pyrimidine and arginine mutants showed no de-repressed levels of these enzymes.
