A model for the structure of a novel lectin, PCL-M.

Pleurotus cornucopiae synthesizes two types of lectins, PCL-F and PCL-M, in a developmental-stage-specific manner. The former occurs in a fruiting body, and the latter does only in a solid-grown mycelial aggregate and appears just prior to fruiting body formation, indicating the participation of PCL-M in the process of fruiting body formation. The most active form of PLC-M is composed of an oligomer (hexamer to octamer) of the subunits linked through disulfide bonds.
