hex·os·a·min·i·dase

(hek'sōs-ă-min'i-dās),
General term for enzymes hydrolyzing N-acetylhexose (for example, N-acetylglucosamine) residues from gangliosidelike oligosaccharides. At least four specific enzymes carrying out this type of reaction are known: α-N-acetyl-d-galactosaminidase, α-N-acetyl-d-glucosaminidase, β-N-acetyl-d-hexosaminidase, and β-N-acetyl-d-galactosaminidase, each being specific for the configuration and type of sugar included in the name.

/hex·os·amin·i·dase/ (hek″sōs-ah-min´ĭ-dās)
1. any of the enzymes that cleave hexosamines or acetylated hexosamines from gangliosides or other glycosides.
2. a specific hexosaminidase acting on keratan sulfate and ganglioside GM2 and related compounds.

(heks-ōs'ă-min'i-dās)
General term for enzymes cleaving N-acetylhexose residues from gangliosidelike oligosaccharides.

hexosaminidase

an enzyme that catalyzes the cleavage of hexose from ganglioside GM2. Occurs in two forms, A and B. Deficiency occurs in GM2gangliosidosis of dogs, cats and pigs.
