Alternate conformer and HOH clashes
Dear All, I am having trouble refining multiple conformers that would clash into a neighbouring side chain that also has an alternate conformer. An attempt to clarify: Lets say a Tyr residue has conformation A1, but also moves into a position B1. In postition B, its side chain would clash into a neighbour Phe A2. However this Phe has another conformation B2. Bottom line, B1 and B2 would not clash, neither would A1 and A2. Any other combo (A1 B2, etc...) would clash. When I model it all in I see problems... I encounter the same situation with partially occupied HOHs. Whats the best way to deal with this Thank you -- Yuri Pompeu
Hi Yuriy,
Could you swap the A,B assignment for PHE?
The general rules are:
altloc " " (blank) interacts with all other altloc
altloc "X" only interacts with " " and "X"

Hi Yuri, yes Ralf's suggestion should solve this, otherwise please send the PDB file with involved residues and tell how you expect them to behave in refinement. Pavel. On 7/23/11 12:04 PM, Yuri wrote:
