On pages titled with a [[PDB code]], Proteopedia shows biological unit 1 by default, with an option to show the asymmetric unit instead. A simple example is [[3hyd]]: biological unit 1 has 4 small peptide chains, while the asymmetric unit has a single chain. A large example is [[1pov]], the polio virus capsid. When biological unit 1 becomes too large for JSmol to handle effectively, it is displayed in [[Molstar|Mol*]] ("[[Molstar]]") instead of [[JSmol]]. An example is the much larger capsid of Eastern Equine Encephalitis Virus, [[6mx4]]. | |||
