The only evidence of this disorder is the appearence of methyl groups CMB and CMC as vinyls. These extra atoms are called CBBB and CBCB. THE LOOP CONTAINING RESIDUES 32-38 IS DISORDERED. THERE IS NO OBSERVED ELECTRON DENSITY FOR THESE RESIDUES AND THEIR POSITIONS AND CONFORMATIONS ARE NOT RELIABLE.
