- •
Catalase isoforms were isolated and characterized from mango stone weevils.
- •
CAT I was a general catalase and CAT II was an immune-regulated catalase.
- •
CAT II production in adult weevils was abolished by fungal infection.
- •
Kd and Vmax values proved CAT II as the most active catalase.
- •
CAT II activity was less affected by inhibitors and metal ions.
