Figure 5From: Integrated allosteric regulation in the S. cerevisiae carbamylphosphate synthetase – aspartate transcarbamylase multifunctional proteinUTP inhibition curve of the CPSase from the mutant Glu 2182→Lys. The percentage of inhibition by UTP was tested under the standard conditions as indicated in the Methods in the presence of increasing concentrations of UTP. The kinetic data were fit to the Hill equation : Back to article page
