programs for superimposing protein structures

[Steven R. Herron]

Hi,

I am looking for several programs to superimpose several structurally
similar protein structures.  Several of the proteins I am interested in
have very similiar structures but have various degrees of sequence
homology.  For the proteins with strong sequence homology I have been
using LSQMAN with good results, but I have been having trouble with the
proteins that have almost no sequence homolgy.

What programs do you use to superimpose your structurally related
proteins?  


                                   Thanks,
                               Steven Herron
