hanging-drop vapour diffusion method at 20°C. Crystallization of aminotripeptidase and a derivative carrying a C-terminal His tag. Native peptidase diffracts to 2.9 A, His-tag peptidase T diffracts to 2.6 A, the selenomethionine derivative of the enzyme does not yield good crystals. His-tag derivatives not only facilitates protein purification but can also result in crystals of improved quality
