| xyloglucan | <plant biology> Plant cell wall polysaccharide containing a backbone of _(1-4) linked glucose residues to most of which single xylose residues are attached as side chains. Galactose, fucose and arabinose may also be present in smaller amounts. It is the major hemicellulose of dicotyledonous primary walls and acts as a food reserve in some seeds. (18 Nov 1997) |

| xyloglucan 2-fucosyltransferase | <enzyme> Adds 1,2-alphafucosyl units to plant xyloglucans Registry number: EC 2.4.1.- Synonym: GDP-fucose-xyloglucan 1,2-alpha-l-fucosyltransferase (26 Jun 1999) |
| xyloglucan 2-galactosyltransferase | <enzyme> Attaches galactose in a 1,2-beta-linkage to xylosyl side chains that are linked 1,6-alpha- to the 1,4-beta-glucan backbone of plant xyloglucans Registry number: EC 2.4.1.- Synonym: xg galactosyltransferase (26 Jun 1999) |
| xyloglucan 4-beta-D-glucosyltransferase | <enzyme> Catalyses formation of xyloglucan from udp-glucose Registry number: EC 2.4.1.- Synonym: xylo-glctransferase, xyloglucan glucosyltransferase (26 Jun 1999) |
