I need some hints from people who really know how to deal with the burgeoning 
database (I'm a crystallographer / biochemist):

I'm interested in the catalytic domain of a protein found on many plasmids & 
transposons.  I'd like to make a "sequence logo" or other 
informative-at-a-glance display of which residues are most conserved. 
Blast gives me pages of 99% identical proteins (mostly from other S. aureus 
strains), and I'm too lazy to pick "representatives" manually from further down 
the list.  What is the best way to get a list of related proteins that are all, 
say, <90% identical to other proteins in the list?

many thanks,
   Phoebe
