Residues simultaneously refined in two or more conformations are: Val53, Leu66, Ser86, Lys87, Leu99, Ser113, Ser130, Gln135, Asp165, Ser166, Ser170, Gln175, Ser217, Lys230, Ser236 Disordered waters are: HOH271 which is close to HOH272; HOH349 which is close to HOH350; HOH756 which is close to Lys230 in conformation 1, but makes an H-bond to Lys230 in conformation 2. His40 and HIS91 are MONOPROTONATED ON THE EPSILON NITROGEN. His57 is doubly protonatd.
