Abstract
Inha enzyme crystals and methods of growing said crystals are presented. Three crystal forms of the Inha enzyme with discrete unit cell parameters were obtained. The crystals of the Inha enzyme are of sufficient size and quality for x-ray crystallographic determination of the three dimensional structure of the Inha enzyme in concert with heavy atom derivatives of said crystals. With the three dimensional structure of the Inha enzyme, compounds which inhibit the biochemical activity of the Inha enzyme may be developed.
