Technical information
General information
Name: Fzd5 (g180-c539) y278a (apoform)
PDB id: Homo
Description: The study investigated conformational/structural differences between wild-type FZD5 and single-point mutants with interesting characteristics as determined in wet-lab experiments. Equilibration was done separately for each replica. Coordinate file is after equilibration1. Unbiased MD, NPT ensemble
