    Abstract:
    KA-prep, a culture filtrate of Bacillus circulans KA-304 grown on a cell-wall preparation (CWP) of Schizophyllum commune, has been reported to have an activity to form protoplasts from S. commune mycelia. The SDS-polyacrylamide gel electrophoreses described here demonstrated that a specific proteinous component (molecular weight: 150,000) occurred in KA-prep. The protein (P150T) was also formed in culture filtrates with CWP of several basidiomycetes, which could release the protoplasts, suggesting that the component was an indispensable factor for protoplast formation. P150T, isolated from an ammonium sulfate fraction of KA-prep (0-30% saturation), did not have any protoplast-forming activity. Results were obtained indicating that P150T participates in protoplast formation together with chitinase(s) and beta-glucanase(s) in KA-prep. The N-terminal amino acid sequence indicated an analogy of P150T to mutanase (alpha-1,3-glucanase) from Bacillus sp. RM1, and actually P150T hydrolyzed mutan as well as S-(alpha-1,3) glucan from S. commune.
