Regulation of Synthesis for Non-Cellulolytic Fungal β-(1,3)- and β-(1,6)- Glucanases

Abstract

The non-cellulolytic β-(1,3)- and β-(1,6)- glucanases capable of degrading the naturally occurring β-(1,3)- and β-(1,6)- glucans have been reported to be produced by many filamentous fungi, although unlike the β-1,3-glucanases, the production of multiple β-1,6- glucanases appears to be quite rare in fungi. To support the effort to realize the industrial potential of these enzymes, cloning of the gene/s encoding them and their expression in host cells in sufficiently large quantities is required. However, clarification is needed on how the synthesis and the formation of their multiple forms are regulated differentially. This review considers this group of enzymes and in particular their multiple isoform and regulation of synthesis. This information and discussion will assist us to get insight their functions in the fungi that synthesize the enzyme.
