An extreme example is a virus capsid. The capsid of the Simian Virus 40 (SV40) contains 360 copies of the VP1 protein chain, present in 6 copies in the published PDB file [[1sva]]. An extremely simplified model of the capsid is displayed at [[SV40_Capsid_Simplified]], but this model is oversimplified for some purposes, and required special techniques to construct. We can get the full capsid model from any of [[biological unit|several servers]]. We recommend getting it from the [http://viperdb.scripps.edu | An extreme example is a virus capsid.

The full SV40 capsid model (360 copies of the VP1 protein chain, minus hydrogen atoms) is a PDB file of 70 megabytes, much too large for default java/Jmol memory. Below are instructions for getting the much smaller alpha carbon atom model. These instructions should work for most virus capsids. | The full SV40 capsid model (360 copies of the VP1 protein chain, minus hydrogen atoms) is a PDB file of 70 megabytes, much too large for default java/Jmol memory.
