About this 3D model

This is a "Jelly Roll" protein. Not a protein found in Jelly Rolls, but a kind of protein fold: http://en.wikipedia.org/wiki/Beta_barrel#Jelly_roll This one is based on PDB structure 2QZ3, a "family 11 glycoside hydrolase", aka, xylanase: http://www.rcsb.org/pdb/explore.do?structureId=2qz3 STL file created using VMD: http://www.ks.uiuc.edu/Research/vmd/ The protein backbone is represented in "cartoon" form.
