Changes in stability and allosteric properties of aspartate transcarbamoylase resulting from amino acid substitutions in the zinc-binding domain of the regulatory chains.
Changes in subunit interaction energies linked to the allosteric transition of the regulatory enzyme aspartate transcarbamoylase (ATCase; EC 2.1.3.2) from Escherichia coli are localized in part at interfaces between the six catalytic (c) and six regulatory (r) polypeptide chains. Site-directed mutag...
