===Virus Capsids===
===Virus Capsids===
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 required special techniques to construct. We can get the full capsid model from any of [[biological unit|several servers]]. For reasons explained [[biological unit|there]], the most useful model is obtained from the MakeMultimers server. The full capsid model (360 copies of the VP1 protein chain, minus hydrogen atoms) is a PDB file of 70 megabytes, 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.

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/ViperDB at Scripps], a server specialized in virus capsid structures.
