Abstract excerpt
The allosteric properties of aspartate transcarbamylase from E coli have been investigated by a combination of genetic, biochemical and structural studies. Based on the X-ray structures of the enzyme in T and R state established by Lipscomb et al, we have analyzed the interactions between the 12 polypeptide chains and have identified subunit interfaces that play a major part in the allosteric mechanism: the c1c4...
