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.
