The enzyme phospholipase C-beta (PLCbeta) is a crucial regulator of intracellular calcium levels whose activity is controlled by heptahelical receptors that couple to members of the G(q) family of heterotrimeric G proteins. We have determined atomic structures of two invertebrate homologs of PLCbeta (PLC21) from cephalopod retina and identified a helix from the C-terminal regulatory region that interacts with a conserved surface of the catalytic core of the enzyme. Mutations designed to disrupt the analogous interaction in human PLCbeta3 considerably increase basal activity and diminish stimulation by Galpha(q). Galpha(q) binding requires displacement of the autoinhibitory helix from the catalytic core, thus providing an allosteric mechanism for activation of PLCbeta.
