The loop comprising the sequence "RDPNSEE" between Phe_H97 and Asn_H99 is not visible and is not included in the model. Residues simultaneously refined in two or more conformations are: Arg_L35, Val_L75, Arg_L79, Lys_L112, Leu_H41, Leu_H46, Gln_H73, Ser_H109, Pro_H185, Thr_H208, Lys_H224, Ser_H246, Gln_H254. Discretely disordered waters are HOH_212 and HOH_323. His_H40, HIS_H57, and His_H107 are doubly protonated. HIS_H91 is monoprotonated on the epsilon nitrogen No energy terms are included Og_Ser_H195, HOH_383, and O6' of the inhibitor. These atoms form a short hydrogen-bonding network.
