<br>
I'm seing something strange with secondary structure assignments in
peptides. Two examples: PDB 1axc has a peptide bound to PCNA with beta
strand interactions and chimera doesn't pick it up as a strand. In the
other example, 1rxz, it picks up the strand in a similar peptide but
the strand disappear when I run matchmaker with 1ul1 (which also has a
strand at the c-terminus that is not picked up. Is there any
explanation? Are the criteria for secondary structure assignments to
strict?<br>
<br>
One more thing that may have been asked already!! how does one keeps
the NH and CO of the peptide bond displayed in the ribbons view?<br>
<br>
Thanks<br>
<br>
