Looking inside for the active site of 3QXE

This is just a couple of rough pictures of 3QXE (the nitrile hydratase from Pseudomonas putida), once again from PyMol, showing a ribbon view of it with the active site cobalt-binding residues shown as CPK spheres, followed by a surface model with some of the active site just visible inside. I have been careful to keep it oriented similarly to the AJ270 nitrile hydratase in the previous post.
