Hydrolyzes the non-reducing end N-acetyl-D-hexosamine and/or sulfated N-acetyl-D-hexosamine of glycoconjugates, such as the oligosaccharide moieties from proteins and neutral glycolipids, or from certain mucopolysaccharides. The isozyme B does not hydrolyze each of these substrates, however hydrolyzes efficiently neutral oligosaccharide. Only the isozyme A is responsible for the degradation of GM2 gangliosides in the presence of GM2A.By similarity

There are 3 forms of beta-hexosaminidase: hexosaminidase A is an heterodimer composed of one subunit alpha and one subunit beta (chain A and B); hexosaminidase B is an homodimer of two beta subunits (two chains A and B); hexosaminidase S is a homodimer of two alpha subunits (By similarity). The composition of the dimer (isozyme A versus isozyme S) has a significant effect on the substrate specificity of the alpha subunit active site (By similarity).

<p>The checksum is a form of redundancy check that is calculated from the sequence.
