[modeller_usage] Block Ligand stereo chemistry problem

["Andre Fischer" <>]

Hi all,

I am modelling a Protein with a ligand. The Ligand comes from the pdb
template as a blk. Modeller works fine and the protein model seems
reasonable, except that the modelled ligand is mirrored along its length
axis compared to the template ligand. Also BLK Residues are defined
rigid. some stereo operations seem to be allowed. How can i get rid of
those? I want the ligand only to act as a steric constraint.

Thank you very much
