| Addtional Information | FUNCTION:Defense against chitin containing fungal pathogens.Binds the hyphal tips, lateral walls and septa of fungi and degrades mature chitin.CATALYTIC ACTIVITY:Random hydrolysis of N-acetyl-beta-D- glucosaminide 1,4-beta-linkages in chitin and chitodextrins.BIOPHYSICOCHEMICAL PROPERTIES:pH dependence: Optimum pH is about 5.0. 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. |
