構造決定の手法: フーリエ合成 / 解像度: 1.6→7 Å / σ(F): 1.8 / 立体化学のターゲット値: X-PLOR force field 詳細: Residues simultaneously refined in two or more conformations are: Val53, Leu66, Ser86, Lys87, Ser110, Ser113, Ser130, Lys159, Ser166 Ser170, Ser217, Lys230, Ser236, Ser244 Note that HOH383 ...詳細: Residues simultaneously refined in two or more conformations are: Val53, Leu66, Ser86, Lys87, Ser110, Ser113, Ser130, Lys159, Ser166 Ser170, Ser217, Lys230, Ser236, Ser244 Note that HOH383 makes short H-bonds to OgSer195 and O6' of the inhibitor Disordered waters are: HOH600 which is close to HOH601, which in turn is close to HOH602; HOH465 which is close to sulfate_466; HOH396 which is close to HOH397; HOH422 which is close to a symmetry-related equivelent of HOH423 HOH654 which occupies the space available when Lys87 is in conformation # 1. HOH674 which is close to HOH675; HOH696 which is close to HOH697; His40 and HIS91 are MONOPROTONATED ON THE EPSILON NITROGEN. His57 is doubly protonatd.
