HOH “waters,” context interpreted: (a) Original fitting shows clash with Lysine methylene: HOH B283 at 2.0 Å in 6aht,38 and (b) shows a rebuilt, H‐bonding lysine rotamer. (c) Clash of HOH 1033 with Cδ2 of the backward‐fit His 73 of 1bkr at 1.1 Å.39 (d) Shows a “water” where an alternate conformation of Cys186 Sγ can be modeled for the 91–186 disulfide bond in http://firstglance.jmol.org/fg.htm?mol=3ajd at 1.27 Å.40 (e) Shows an HOH pair modeled at full occupancy that clash with each other and with mislabeled backbone alternates of Leu 105 at 0.88 Å in the http://firstglance.jmol.org/fg.htm?mol=1gwe bacterial catalase,41 and (f) shows a rebuild with the higher‐density Leu and water alternates as altA at 60% occupancy and the lower‐density ones at 40%
