Has antifungal activity against A.alternata, A.cucumerina, A.niger, C.gossypii, F.oxysporum, F.oxysporum subsp melonis, F.moniliforme, T.cucumeris, and V.dahliae. Has no chitinase or agglutination activities. By ethylene. Belongs to the parathyroid hormone family. 14 of the 15 residues are identical to an internal region of human parathyroid hormone. That seems quite an incredible 'coincidence'.
