This nucleosome model was used in PathogenAR for the Papilloma: The HPV Minichromosome Module.
The 3D model was originally generated for:
Porter SS, Liddle JC, Browne K, Pastrana DV, Garcia BA, Buck CB, Weitzman MD, McBride AA. Histone Modifications in Papillomavirus Virion Minichromosomes. mBio. 2021 Feb 16;12(1):e03274-20. doi: 10.1128/mBio.03274-20. PMID: 33593981.
PDB 1KX5 was used to generate the base model in ChimeraX. H2A is depicted in light green, H2B in dark green, H4 in yellow, and H3 in orange. A stick representation was added of one H3 tail where acetylation is in red, methylation in magenta, and lysine residues in blue.
The .wrl included is not for 3D printing, it was uploaded for the 3DPX viewer only.
The .fbx file is also not printable. It is UV mapped for AO purposes and vertex colored. Vertex colors were not used for the PathogenAR application.
