3D structure of AJ270 NHase

We have worked with the nitrile hydratase from Rhodococcus erythropolis AJ270 which was a bacterium which was collected on the banks of the river Tyne in Newcastle. The key authors who have worked with this bacterium in synthesis over the years are Otto Meth Cohn (at Sunderland University) and Mei-Xiang Wang  (originally working with OMC but now at the Chinese Academy of Sciences, Beijing). M-X W has published a crystal structure of the nitrile hydratase from AJ270, and it can be found on PDB as 2QDY here. A little bit of playing with the data using PyMol and you can see how the two subunits fit together, and how there is a small channel from the exterior of the enzyme down into the active site.
