Methyl and hydroxyl hydrogens on single-conformer sidechains were each positioned at a torsion angle that best satisfied positive difference electron density (using instructions HFIX 137 and HFIX 147, respectively). It should be noted that the length of donor-hydrogen bonds in this structure are likely shorter than their true internuclear distance; these bond lengths are defined by SHELXL-97 parameters. The positions of only four hydrogen atoms were allowed to refine freely: His57 HD1, His57 HE1, Ser214 HG, and Gly193 HN. During the final stages of refinement, geometrical restraints were released for all non-hydrogen atoms in residues with single conformations. See publication for more details.
