<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;">Hi Volodymyr,<div class="">It's not really complex: only the ligand and ion residues that are in all 3 structures (with same residue numbers and names and atom names) will be in the morph. So if you didn't manually edit anything, as per what I sent before, the resulting morph will only contain the ATP and MG in chain T and in chain U. None of the ATP, ADP, or MG residues in chains V, X, Y, Z will be included.</div><div class=""><br class=""></div><div class="">I tested this by opening the 3 structures and (to speed up testing removed all chains except the ATP synthase, namely T,U,V and X,Y,Z) and it did agree with the above predictions. See images below of input models and output morph.</div><div class=""><br class=""></div><div class="">I hope this helps,</div><div class="">Elaine<br class=""><div class="">-----<br class="">Elaine C.

So it depends what order you are visiting the 3 structures as to which nucleotide and ion residues will be present.<br class=""><br class="">If you wanted ALL of those residues to be present in the whole morph, you may need to make manually edited versions of the models that contain them where they are missing (e.g. 6rd9 does not have ADP601 and MG 602 in chain Z). I realize that is not accurate to display along with the structures that did not originally contain them, but these atoms could be present in the morph and then only displayed at the appropriate times in conjunction with the states of the complex that do actually contain them.<br class=""><br class="">I hope this helps,<br class="">Elaine<br class="">-----<br class="">Elaine C.
