詳細 | THE OCTAMER MENTIONED FOR BIOMOLECULE 1 IS BELIEVED TO BE A CRYSTALLOGRAPHIC ARTIFACT DUE TO LIGAND BINDING. IT CONSISTS OF FOUR HDAC8 MONOMERS, EACH COMPLEXED WITH AN ACETYLLYSINE SUBSTRATE PEPTIDE. THE DIMER QUATERNARY STRUCTURE OF BIOMOLECULES 2, 3, 4, AND 5 MENTIONED IN REMARK 350 ARE BETWEEN AN HDAC8 MONOMER AND ITS ACETYLLYSINE SUBSTRATE PEPTIDE. DYNAMIC LIGHT SCATTERING STUDIES HAVE INDICATED THAT HDAC8 EXISTS AS A MONOMER IN SOLUTION |
