What is cellulase made of?

It is made up of proteins. Cellulase is a generic term for a group of enzymes that degrade cellulose to produce glucose. It is not a monomer enzyme, but a multi-component enzyme system that acts synergistically. Cellulase is a complex enzyme mainly composed of exo-β-glucanase, endo-β-glucanase and β-glucosidase, as well as a highly active xylanase. Cellulases act on cellulose and products derived from cellulose. Microbial cellulase is of great importance in converting insoluble cellulose into glucose and destroying the cell wall in fruit and vegetable to increase the yield of juice.
