Anisotropic refinement without stereochemical restraints on main chain atoms with low Beq (<15 A**2). In both molecules (A and B) there is a salt bridge between the C-terminus and the Arg1 side chain. The Arg5 side chain in molecule A is modeled in two conformations. The Val21 and Tyr27 side chains in both molecules are modeled in double conformation. His25 has different protonation and conformation in the two molecules. The zinc and sulfate ions lie on a common two fold axis. One MPD and two glycerol molecules are modeled in the solvent region. Blocked full-matix least-squares calculations were performed at the conclusion of the refinement.
In remark 500, the atoms in all cases represent complementary pairs with partial occupancies.

Four molecules of the inhibitor coordinate a single zinc cation in a tetrahedral fashion via their Glu19 side chains. Two of them (molecules A and B) constitute the contents of the asymmetric unit. The full coordination sphere is generated by the operation: -X, -Y, Z, of a two-fold axis. The zinc cation has a special position (occupancy 0.5) on this two-fold axis.
