The model of Mic60 and Mic19 in CJs was created and prepared by E. Werner, RNS Berlin (www.rns.berlin), who granted copyrights. The model comprises the crystal structures of the CC region of Mic60 from L. thermotolerans (ltMic60CC, residues 235 to 382), the LBS 1 and mitofilin domain of ctMic60, and the CHCH domain of ctMic19 (Mito2_CHCH). In this, the sequence of ltMic60 was used as template. All other parts of Mic60 were modeled as unstructured regions. A CJ diameter of 17.5 nm was used (13 (link)). The model was generated using the Maya software from Autodesk Inc. (www.autodesk.com/products/maya/) and Modeling kit and Rigging kit of the plugin Molecular Maya (mMaya) from Digizyme Inc. (https://clarafi.com/tools/mmaya/).
