Function

function

Heme-based protein that deliver nitric oxide gas (NO) to the victim while feeding, resulting in vasodilation and inhibition of platelet aggregation. Also binds tightly to histamine, which is released by the host to induce wound healing (By similarity).
Specifically inhibits factor IXa-catalyzed activation of factor X in the presence of calcium and phospholipids irrespective of the presence or absence of factor VIIIa.
