Keratan sulfate (KS) is degraded by various enzymes including endo-beta-galactosidase, keratanase, and keratanase II, which are used for the structural analysis of KS. We purified a novel KS hydrolase, endo-beta-N-acetylglucosaminidase, from the cell pellet and conditioned medium of Bacillus circulans

This overview covers the endo-beta-galactosidases; enzyme is capable of hydrolyzing a wide range of glycoconjugates. Endo-beta-galactosidases from numerous sources are discussed in terms of their substrate specificities and substrates, as well as their practical research applications.

Enzymatic synthesis of GlcNAc-terminated poly-N-acetyllactosamine beta-glycosides GlcNAcbeta1,3(Galbeta1,4GlcNAcbeta1,3)(n)Galbeta1,4GlcNAcbeta-pNP (n=1-4) was demonstrated using a transglycosylation reaction of Escherichia freundii endo-beta-galactosidase. The enzyme catalyzed a transglycosylation reaction on GlcNAcbeta1,3Galbeta1,4GlcNAcbeta-pNP (1), which served both as a donor and an acceptor, and converted 1 into

The zona pellucida (ZP) surrounding the mammalian oocyte is composed of three glycoprotein components (ZPA, ZPB, and ZPC). Mammalian sperm bind to carbohydrate chains of a ZP glycoprotein in the initial phase of fertilization. Sperm-ligand carbohydrate chains have been characterized

To evaluate the use of neoepitope monoclonal antibody BKS-1, which recognizes keratanase-generated keratan sulfate (KS) stubs on keratan sulfate proteoglycans in human cornea, limbus, and sclera. BKS-1 specifically recognizes a keratanase-generated neoepitope [N-acetyl-glucosamine-6-sulfate (GlcNAc-6-S)] at the nonreducing terminal of corneal
