PHOSPHOFRUCTOKINASE, INHIBITED T-STATE
OverviewOverview
Comparison between the crystal structures of low- and high-affinity forms, of phosphofructokinase shows a close coupling between the change of, quaternary structure and local changes triggered by binding of the, allosteric effectors. These concerted changes link all the substrate and, effector sites in the tetramer, and explain the change of affinity for the, cooperative substrate.
