Crystallization

Crystalization Experiments
Details THE CRYSTAL WAS PREPARED WITH CO CRYSTALLIZATION METHOD. 9X MUTANT PROTEASE HAS NINE POINT MUTATIONS COMPARED TO WILD TYPE: L10V,K20M,L24I,S37D,M46I,I54V,L63P,A71V,V82T THERE IS ONE PROTEASE DIMER IN AN ASYMMETRICAL UNIT. THE TWO MOLECULES ARE LABELED AS CHAIN A AND CHAIN B. THERE IS ONE L-735,524 INHIBITOR MOLECULE LABELED AS MK1.
