Some very mobile side chains were modeled at either 50% or zero occupancy. The occupancy of absent side chain atoms was set to zero for the following: RES 396 ARG NE->end has zero occupancy. RES 436 GLN CG->end has zero occupancy. Partially occupied side chain atoms modeled at 50% for the following: RES 146 ARG atoms CZ, NH1,NH2; RES 163 LYS atoms CE,NZ; RES 273 LYS atoms CG,CD,CE,NZ; RES 278 LYS atoms CG,CD,CE,NZ; RES 279 GLU atoms CG,CD,OE1,OE2; RES 396 ARG atoms CG,CD (REST ZERO); RES 404 ASP atoms CG, OD1,OD2; RES 468 LYS atoms CG,CD,CE, NZ; Regarding the close contacts in remark 500: ARG 396 NH1 (zero occupancy); GLU 279 OE2 50% occupancy; ARG 202 NE very aniostropic B = 33; All of the flagged waters are modeled at 50% occupancy.
