title: A difference in the specificities of human liver N-acetyl-beta-hexosaminidases A and B detected by their activities towards glycosaminoglycan oligosaccharides.
abstract: N-Acetyl-beta-hexosaminidases A and B differ in their activities towards oligosaccharides prepared from glycosaminoglycans. Trisaccharides from hyaluronic acid and desulphated chondroitin 4-sulphate were hydrolysed by N-acetyl-beta-hexosaminidase A, but not by N-acetyl-beta-hexosaminidase B.
