<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; "><DIV>Hello,</DIV><DIV>I am wondering if there is an option in Chimera to reconstruct exact place for binding peptide. I do have x-ray structures and binding peptide was incorporated as a C-terminal extension. When I used these structures, I do not get protein-peptide contact information in our model.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Is there any way to reconstruct x-ray structure data with the right peptide binding information? Any help would be appreciated.
