Addtional InformationFUNCTION:Extracellular proteinase found in the pitcher fluid of carnivorous plants. Digest prey for nitrogen uptake.CATALYTIC ACTIVITY:Similar to pepsin, but also cleaves on either side of Asp and at Lys-|-Arg.ENZYME REGULATION:Inhibited by pepstatin and by diazoacetyl-D,L- norleucine methyl ester (DAN) in the presence of Cu(2) ions (By similarity).BIOPHYSICOCHEMICAL PROPERTIES:pH dependence: Optimum pH is 2.6. Retains 95% and 79% of the original activity after incubation for 30 days at pH 3.0 and pH 10.0 respectively; Temperature dependence: Optimum temperature is 55 degrees Celsius. Thermostable up to 50 degrees Celsius. Retains 60% of the original activity after incubation for 30 days at 50 degrees Celsius;SIMILARITY:Belongs to the peptidase A1 family.
