| 摘要 |
The purpose of the present invention is to isolate a gene encoding novel exo-, or endo-beta-1,3-glucanase, to obtain a microorganism having an enhanced expression of said gene and to degrade beta-1,3-glucan to its low molecular weight form by means of said enzymes. The present invention relates to a gene or DNA encoding novel enzymes having beta-1,3-glucanase activity (exo-, or endo-beta-1,3-glucanase), a recombinant expression vector comprising them, a microorganism having the recombinant expression vector, the novel enzymes having beta-1,3-glucanase activity, and a method for the production of said enzymes.
