Homology modeling of the cellulose-binding domain of a pollen allergen from rye grass: structural basis for the cellulose recognition and associated allergenic properties
A three-dimensional model of the cellulose-binding domain of the rye-grass pollen allergen Lol pI built by homology modeling is proposed as a structural scaffold for expansins and other expansin-related proteins. A groove and an extended strip of aromatic and polar residues presumably account for the cellulose-binding properties of the protein domain. Two of the four predicted T-cell epitopes readily exposed on the surface of the cellulose-binding domain match with previously reported IgE-binding regions. A close structural relationship occurs between the cellulose-binding and allergenic properties. (C) 2002 Elsevier Science (USA). All rights reserved.
