Abstract
Purified aspartate carbamoyltransferase from Escherichia coli K12 (carbamoylphosphate: L-aspartate carbamyltransferase, EC 2.1.3.2) shows greater activity with nucleotide effectors as the magnesium nucleotide complex than with similar amounts of the sodium nucleotide. Regulation of aspartate carbamoyltransferase activity in vivo may occur by changes in the total concentration of regulatory nucleotides or, under conditions of magnesium-limited growth, by variation of the saturation of the nucleotides with magnesium.Entities:
