摘要：
A novel antifungal protein with a molecular mass around 50 kDa was purified from seeds of Sesbania virgata (Cav.) Pers. using ammonium sulfate fractionation followed by gel filtration on a Sephadex G-75 Superfine (Sigma) column and reverse-phase high performance liquid chromatography on a C8 column. The protein, designated FP1-A, with a novel N-terminal sequence AMVHSPGG(S) FS(P), showed growth inhibitory activity of filamentous fungi Aspergillus niger, Cladosporium cladosporioides, Colletotrichum gloeosporioides and Fusarium solani.
