ClustalW analysis of pdb sequences

Following on from looking at the similarity of the pdb files, I thought I would run a ClustalW analysis of the primary sequences I used for that analysis. A lot are very similar (>98%) as you might expect, and once again it is obvious these files actually represent one iron centred and two cobalt centred templates. The iron centred template has scores between 40 and 50% for the cobalt centred pair, and the score between the two cobalt centred templates is about 60%.
