Protein Models
Contents |
We have determined the structures of some proteins we want our mutants to express. Others could be homology modelled due to existing 3D models that had high similarity to the ones we are working with.
Mutant 1
AMO
Figure 1: Ammonia monooxygenase (AMO). Homology models of all three subunits of AMO.
At the time of writing none of the three subunits from Nitrosomonas Europaea are available as 3D structures, so each of the subunits was identified at [http://www.uniprot.org/ UNIPROT], and their sequence was homology modelled 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.
