EC Number 3.2.1.2
Enzyme Function
Temperature Dependency
PH Dependency BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 5. Highly active at acidic pH range 4-7. Retains over 80% of maximum activity at 4.0. At higher pH values the activity decreases markedly, with more than 50% of activity lost at pH 8.0. {ECO:0000269|PubMed:30515829};
