<div style="font-family: 'Times New Roman'; font-size: 16px; "><div>Hi All,</div><div><br /></div><div>I am trying to work on the design of a protein, and am unable to figure out the correct tool to accomplish this:</div><div><br /></div><div>I have a protein and a region that I would like to replace with another region. Essentially, the insert is a long motif. (Literally making a chimeric structure). In Chimera, I can merge the two pdb's at one terminus, however I can't seem to create the bond at the other terminus, once the models are merged. Is this possible? If not, does anyone know of other programs out there that can accomplish this, and any interest in putting it in chimera? </div><div><br /></div><div>-Jared Adolf-Bryfogle</div><div>PhD Candidate</div><div>Drexel College of Medicine</div></div>
