Patent ID: 6906024

Claim:
A fabric softening protein hybrid comprising an amino acid sequence comprising a cellulose binding domain linked to a fabric softening protein; wherein said fabric softening protein is linked to said amino acid sequence comprising a cellulose binding domain, via a non-amino acid linking region; wherein the cellulose binding domain is selected from the group consisting of CBD Cellulozome from Clostridium cellulovorans , CBD E3 from Thermonospora fusca , CBD-dimer from Clostridium stecorarium XynA, CBD from Bacillus agaradherens , and combinations thereof; further wherein said non-amino linking region is a polymer selected from the group consisting of polyethylene glycol derivatives, nucleophilic polyethylene glycol derivatives, carboxyl polyethylene glycol derivatives, electrophilically activated polyethylene glycol derivatives, sulfhydryl-selective polyethylene glycol derivatives, heterofunctional polyethylene glycol derivatives, biotin polyethylene glycol derivatives, vinyl polyethylene glycol derivatives, silane polyethylene glycol derivatives, phospholipid polyethylene glycol derivatives, 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide, N-ethyl-5-phenylisoaxolium-3-sulphonate, 1-cyclohexyl-3(2-morpholinoethyl) carbodide metho-p-toluene sulphonate, N-ethoxycarbonyl-2-ethoxy 1,2, dihydroquinoline, glutaraldehyde and mixtures thereof; and further wherein said fabric softening protein is selected from the group consisting of: hydrolases, lyases, oxidoreductases, ligases, transferases, isomerases, cellulases, xylanases, mannanases, arabinofuranosidases, acetylesterases, chitinases, polyamino acid resin solutions, C 18 alkyl quaternary wheat protein derivatives and combinations thereof.
