THE PROTEIN POWDER WAS DISSOLVED IN 330 MM NA CACODYLATE BUFFER AT PH 5.6 TO A CONCENTRATION OF 10 MG/ML. SUBTILISIN WAS CRYSTALLIZED BY THE BATCH METHOD FROM BUFFER SOLUTION SATURATED WITH NA2SO4 13% (W/V) AS PRECIPITANT1. LONG NEEDLE-LIKE CRYSTALS GREW OVER A PERIOD OF TWO WEEKS TO TYPICAL DIMENSIONS 50 X 50 X 400 UM X UM X UM
