Stable between pH 4 and 8; Temperature dependence: Enzyme activity is retained almost fully under 40 degrees Celsius and completely destroyed at 70 degrees Celsius. At 60 degrees Celsius the activity was over 80% compared to the untreated enzyme;TISSUE SPECIFICITY:Localized in the aleurone cells of the seed endosperm (at protein level).DEVELOPMENTAL STAGE:Levels increase from 23 to 40 days after flowering, and are maintained until maturation (at protein level).SIMILARITY:Belongs to the glycosyl hydrolase 19 family. Chitinase class I subfamily.SIMILARITY:Contains 1 chitin-binding type-1 domain."
