ABSTRACT:
The present invention relates to recombinant .beta.-1,3-glucanase essentially free of proteases. The enzyme is obtained through the use of a recombinant DNA expression vector which comprises a DNA sequence encoding the .beta.-1,3-glucanase gene or mutants and variants thereof placed under the control of an exogenous expression promoter, preferably a bacterial promoter. Also, the .beta.-1,3-glucanase gene may include sequences flanking the open reading frame of the native .beta.-1,3-glucanase gene. The present invention also relates to a microorganism transformed with a recombinant DNA expression vector comprising the .beta.-1,3-glucanase gene or mutants and variants thereof under the control of an exogenous expression promoter.
