Abstract excerpt
We use site-directed mutagenesis to clarify the role of effector-mediated oligomerization changes on the modulation of the activity of Escherichia coli carbamoyl phosphate synthetase (CPS) by its allosteric activator ornithine and its inhibitor UMP. The regulatory domain mutations H975L, L990A and N992A abolished, and N987V decreased CPS oligomerization. The oligomerization domain mutation L421E prevented...
