Hi Elaine,<div><br></div><div>Thanks for suggestions. I'll &nbsp;try them and see how it looks. Ribbons won't do here since I want to show a w.t. protein and mutants with substrate analogues in the active site and how they fit (or clash) so I'm only showing a few residues.&nbsp;</div><div><br></div><div>Thanks again.</div><div><br></div><div>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;Boaz</div><BR><BR>Boaz Shaanan, Ph.D.<br>Dept. of Life Sciences<br>Ben-Gurion University of the Negev<br>Beer-Sheva 84105<br>Israel<br>Phone: 972-8-647-2220 ; Fax: 646-1710<br>Skype: boaz.shaanan</BR></BR>‎
