arylsulfatase

(redirected from arylsulphatase)

ar·yl·sul·fa·tase

(ar'il-sŭl'fă-tās),
An enzyme that catalyzes the hydrolysis of phenol sulfates, including cerebroside sulfates (that is, a phenol sulfate + H2O → a phenol + sulfate anion). Some arylsulfatases are inhibited by sulfate (type II) and some are not (type I).
Synonym(s): sulfatase (2)

arylsulfatase

a group of enzymes active in the hydrolysis of sulfates and the metabolism of mucopolysaccharides; found in liver, pancreas, kidneys and immature monocytes. Several species of molluscs and Aerobacter spp. serve as commercial sources of the enzyme which is used in analytic endocrinology.

arylsulfatase A deficiency
see metachromatic leukodystrophy.
arylsulfatase B deficiency
is the cause of mucopolysaccharidosis VI which occurs in humans and cats. Called also Maroteaux-Lamy syndrome.
