Publication Abstract from PubMed

Regulation of protein function, often achieved by allosteric mechanisms, is central to normal physiology and cellular processes. Although numerous models have been proposed to account for the cooperative binding of ligands to allosteric proteins and enzymes, direct structural support has been lacking. Here, we used a combination of X-ray crystallography and small angle X-ray scattering in solution to provide direct structural evidence that the binding of ligand to just one of the six active sites of Escherichia coli aspartate transcarbamoylase induces a concerted structural transition from the T to the R state.

Direct structural evidence for a concerted allosteric transition in Escherichia coli aspartate transcarbamoylase.,Macol CP, Tsuruta H, Stec B, Kantrowitz ER Nat Struct Biol. 2001 May;8(5):423-6. PMID:11323717^[1]
