| Enzyme Function | FUNCTION: Dual-function toxin that completely inhibits trypsin activity at a molar ratio of 1:1 (dissociation constant of 160 nM) and that inhibits mKv1.3/KCNA3 potassium channel currents (1 uM inhibits 50% of currents). It is thermostable. {ECO:0000269|PubMed:22087336, ECO:0000269|PubMed:22354971}. |
