==Overview==
==PHOSPHOFRUCTOKINASE, INHIBITED T-STATE==
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.

Structural highlights

6pfk is a 4 chain structure with sequence from Geobacillus stearothermophilus. This structure supersedes the now removed PDB entry 5pfk. The February 2004 RCSB PDB Molecule of the Month feature on The Glycolytic Enzymes by David S. Goodsell is 10.2210/rcsb_pdb/mom_2004_2. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
