Figure 1 Yeast cytosine deaminase crystals. Two crystal morphologies were commonly observed: prismatic crystals with typical dimensions of 0.2 × 0.2 × 0.15 mm and long thin rod-shaped crystals with dimensions of 0.5 × 0.1 × 0.05 mm. The rod crystals appeared more often, but diffracted X-rays poorly.
