-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.
 ==About this Structure==
 PFK is a [[Single protein]] structure of sequence from [http://en.wikipedia.org/wiki/Geobacillus_stearothermophilus Geobacillus stearothermophilus]. This structure supersedes the now removed PDB entry [http://oca.weizmann.ac.il/oca-bin/send-pdb?obs=1&id=5pfk 5pfk]. The following page contains interesting information on the relation of 6PFK with [[http://pdb.rcsb.org/pdb/static.do?p=education_discussion/molecule_of_the_month/pdb50_1.html The Glycolytic Enzymes]]. Full crystallographic information is available from [http://oca.weizmann.ac.il/oca-bin/ocashort?id=6PFK OCA].
