Hi Omar,<br><br>Presumably if you know the rotamer the lysine adopts it is from a solved crystal structure, with good B-factors for the atoms?  Anyway, Coot is a crystallographic model building program that lets you play with rotamers (<a href="http://www.biop.ox.ac.uk/coot/">http://www.biop.ox.ac.uk/coot/</a>).<br>

<br>Hi,<br><br>I need to model a protein with the lysine all straight (stuck-up?). How can I say to modeller that only create models with the lysine in that form?? This Lysine is known to be like that. Thanks!!<br><font color="#888888"><br>
