Building protein crystals
Building Protein Crystals by Engineering Methods
It is difficult to build crystals for many proteins. I have a plan that might improve the process. The idea is to use a two-dimensional lattice of an easily crystallized protein as a substrate to which a protein of interest can be attached at identical lattice positions. The two-dimensional template will provide the lattice spacing and determine standardized dimensions for the unit cell of the crystal. The process can also be extended to create membrane protein crystals, for either a solubilized protein of interest or one that is embedded in a lipid layer.

Addendum: 3-4 Angstrom (high resolution) structures are possible (see Reference 5.)
