1. Water soluble chlorophyllase preparation was made from chloroplasts of tobacco plants, using n-butanol and aqueous solution of sodium chloride as the solvents.
2. Some properties of the enzyme were studied.
3. Seasonal changes of enzyme activity and chlorophyll content were studied. Chlorophyllase activity varied in advance of the variation of chlorophyll content.
4. Possible participation of chlorophyllase in the biosynthesis of chlorophyll was. discussed.
