An antifungal protein designated as Psc-AFP, with an apparent molecular mass of 18 kDa, was isolated from a traditional Chinese herb, malaytea scurfpea (Psoralea corylifolia L.). The isolation procedure entailed extraction, cation exchange chromatography on CM FF, gel filtration chromatography on Superdex 75 and reversed-phase high performance liquid chromatography on SOURCE 5RPC column. Automated Edman degradation determined the partial N-terminal sequence of Psc-AFP to be NH2-EWEPVQNGGSSYYMVPRIWA, which displayed homology with plant trypsin inhibitors. The protease inhibitor activity of Psc-AFP was then confirmed by the inhibition on trypsin. Psc-AFP at 10 μM inhibited the mycelial growth of Alternari brassicae, Aspergillus niger, Fusarium oxysporum and Rhizoctonia cerealis, suggesting that Psc-AFP has a role in the defense against pathogens.
