摘要：
A protein with a molecular weight of 40 kDa, capable of inhibiting cell-free translation in a rabbit reticulocyte lysate system with an IC50 of 0.25 nM, was isolated from fruiting bodies of the mushroom Flammulina velutipes. The protein, designated flammulin, was devoid of ribonuclease activity. Flammulin was unadsorbed on DEAE-cellulose at neutral pH and low ionic strength and adsorbed on CM-Sepharose and Affi-gel blue gel under similar conditions. Its N-terminal sequence demonstrates sites of similarity to those of plant ribosome-inactivating proteins (RIPs).
