Code : 1BG3   PDBj   RCSB PDB   PDBe
Header : HEXOKINASE
Title : RAT BRAIN HEXOKINASE TYPE I COMPLEX WITH GLUCOSE AND INHIBITOR GLUCOSE-6-PHOSPHATE
Release Data : 1999-06-08
Compound :
mol_id molecule chains synonym
1 HEXOKINASE A,B ATP-D-HEXOSE-6-PHOSPHOTRANSFERASE
ec: 2.7.1.1
other_details: BOTH MONOMERS HAVE TWO SMALL BREAKS AT KNOWN OR LIKELY TRYPSIN CLEAVAGE SITES. ALTHOUGH ENZYME IS ACTIVE AS A MONOMER, DIMERIZATION OCCURS AT HIGH PROTEIN CONCENTRATION, PARTICULARLY IN THE PRESENCE OF THE INHIBITOR G6P
