Abstract
This invention concerns methods of use for a class of proteins heretofore known as “grass pollen group-⅔ allergens” to modify the properties of cellulose-based materials, changing their mechanical properties, improving their accessibility to agents that chemically modify cellulose structure (such as cellulytic enzymes and chemical reagents), and altering binding of dyes such as Direct Cotton dyes to cellulose.
Claims58
A method of enhancing the hydrolysis of cellulose by cellulase comprising:
- introducing to said cellulose a GR2 protein in the presence of said cellulase.
A method of altering the mechanical strength of cellulosic materials comprising:
- introducing to cellulosic materials a cellulase and a GR2 protein.
A method of increasing the accessibility of cellulose for chemical modification comprising:
- introducing to said cellulose an effective amount of a GR2 protein.
A method of improving the dye release from cellulosic materials (paper, cloth,) comprising:
- introducing a GR2 protein to said materials which have dye hydrogen bonded to said cellulose.
A composition for improving the degradation of cellulose by cellulase comprising
- a GR2 protein and a carrier.
A cellulose degrading composition comprising:
- a GR2 protein, and a cellulase.
A method for improving the enzymatic hydrolysis of glucan bonds in polysaccharides such as cellulose comprising:
- introducing a GR2 protein to said enzyme in the presence of said polysaccharide.
A novel chimeric protein for improving the degradation of cellulose by cellulase comprising:
- a chimeric protein which contains both cellulase and GR2 domains.
