To elaborate a little, it's missing-structure pseudobonds between the last backbone atom of one polymeric residue and the first backbone atom of another. Also, there are analogous criteria for nucleic-acid bonds / missing-structure pseudobonds.<div class=""><br class=""></div><div class="">--Eric<br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Dec 2, 2020, at 11:39 AM, Daniel Esteban Palma Igor <<a href="mailto:daniel.palma.i@ug.uchile.cl" class="">daniel.palma.i@ug.uchile.cl</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Ahh ok.
