PCT No. PCT/US94/10758 Sec. 371 Date Jun. 5, 1996 Sec. 102(e) Date Jun. 5, 1996 PCT Filed Sep. 22, 1994 PCT Pub. No. WO95/08645 PCT Pub. Date Mar. 30, 1995Purified N-acetylglucosaminidase and alpha 1-3,6 Galactosidase endogenous to Xanthomonas have been described. Substrate specificity of isolated enzymes have been identified from GlcNAc beta 1-x and Gal alpha 1-3R, Gal alpha 1-6R, providing improved capability for selectively cleaving a glycosidic linkage in a carbohydrate substrate and for forming modified carbohydrates.
