I'll have a look at your suggestions, although I solved my problem in a different way. I just copied the coordinates of the important symmetry mates into the pdb file containing the original molecule of protein B (and set up a new chain for each of the sym mates). Superimposing protein B (the chain containing the original molecule) on protein A moves all desired sym mates according to the movement of the original molecule. Anyway, getting the translation / rotation matrix is much more convenient than copying all the coordinates... :-)
Thanks once again!
