<br clear="all">Good day to you, currently i am using Chimera to do some bioinformatics analysis, i want to put zinc ion into my predicted protein structure at the known binding sites, but i try to insert :Tools/structure editing/add ion/, but the option did not consists of zinc ion, hence may i know what are the alternative ways to introduce the zinc ion in order to facilitate the downstream application such as docking?? <br>
<br>Hopefully can hear from you as soon as possible.... thank you<br>-- <br>Zhao Yang <br>
