3A8O vs 2QDY

I have been playing with Deepview which offers a handy function where you can overlay pdb files and the resulting structure is colour coded for alignment diversity. Blue indicates really not much at all. As I have mentioned before the pdb for the Rhodococcus species AJ270 is coded as 2QDY and that for Rhodococcus species N-771 is 3A8O. Overlaying these two shows almost everything is dark blue, apart from differences for the two post-translationally modified cysteines in the active site and one bit dangling off the end. So that would be very similar then. You can see the same sort of picture if you overlay these with the 2CYZ too.
