Protein Models
It turns out that the structures of some of the proteins we want our mutants to express have been determined. While others could be homology modelled due to existing 3D models that had high enough similarity to the ones that we are working with.

Mutant 1
AMO
Ammonia monooxygenase
homology models of all three subunits of AMO
At the time of writing neither of the the three subunits from Nitrosomonas Europae is available as 3D structures, so each of the subunits was identified at UNIPROT, and their sequence was homologymodelled using [http://www.cbs.dtu.dk/services/CPHmodels/ CPHmodels-3.2]

The three subunits were combined and aligned to the subunits of the [http://www.pdb.org/pdb/explore/explore.do?structureId=1yew Crystal structure] of particulate methane monooxygenase, hence an overlap of two alpha helices.

- All homology models were made using the free online tool [http://www.cbs.dtu.dk/services/CPHmodels/ CPHmodels v3.2]
- All models were made and visualized in [http://sourceforge.net/projects/pymol/ PyMOL v1.6] which was easily compiled and installed using an [http://pymolwiki.org/index.php/User:Tlinnet/Linux_Install installation script] made by Troels Linnet.
