Keratanase II, Hydrolytic Enzyme Specific to Keratan Sulfate
Keratan sulfate is a sulfated polysaccharide classified as a glycosaminoglycan, an essential component of proteoglycans. It is found in tissues such as the cornea of the eye, joints, and skin, playing crucial roles in these tissues. Additionally, it has been reported to be involved in muscle and lung diseases and is also recognized as a stem cell marker.1)
Keratanase II is a recombinant enzyme expressed in Escherichia coli using a gene derived from Bacillus circulans, and specifically acts on keratan sulfate by hydrolyzing the β1-3 linkage between N-acetylglucosamine (GlcNAc) and galactose (Gal). GlcNAc sulfated in the 6-position is essential for enzyme recognition, and it does not have any effect on whether or not Gals are sulfated.2)
