X-linked ichthyosis is a skin condition caused by the hereditary deficiency of the steroid sulfatase (STS) enzyme that affects 1 in 2000 to 1 in 6000 males. XLI manifests with dry, scaly skin and is due to deletions or mutations in the STS gene. XLI can also occur in the context of larger deletions causing contiguous gene syndromes. Treatment is largely aimed at alleviating the skin symptoms. The term is from the Ancient Greek 'ichthys' meaning 'fish'.
Cerebroside-sulfatase (EC 3.1.6.8, arylsulfatase A, cerebroside sulfate sulfatase) is an enzyme with systematic name cerebroside-3-sulfate 3-sulfohydrolase. This enzyme catalyses the following chemical reaction
Steroid sulfatase (STS), or steryl-sulfatase, formerly known as arylsulfatase C, is a sulfatase enzyme involved in the metabolism of steroids. It is encoded by the STS gene.
Sulfatases EC 3.1.6.- are enzymes of the esterase class that catalyze the hydrolysis of sulfate esters. These may be found on a range of substrates, including steroids, carbohydrates and proteins. Sulfate esters may be formed from various alcohols and amines. In the latter case the resultant N-sulfates can also be termed sulfamates.
Arylsulfatase B is an enzyme associated with mucopolysaccharidosis VI.
Arylsulfatase (EC 3.1.6.1, sulfatase, nitrocatechol sulfatase, phenolsulfatase, phenylsulfatase, p-nitrophenyl sulfatase, arylsulfohydrolase, 4-methylumbelliferyl sulfatase, estrogen sulfatase) is a type of sulfatase enzyme with systematic name aryl-sulfate sulfohydrolase. This enzyme catalyses the following chemical reaction
Iduronate 2-sulfatase is a sulfatase enzyme associated with Hunter syndrome. It catalyses hydrolysis of the 2-sulfate groups of the L-iduronate 2-sulfate units of dermatan sulfate, heparan sulfate and heparin.
N-acetylgalactosamine-4-sulfatase is an enzyme with systematic name N-acetyl-D-galactosamine-4-sulfate 4-sulfohydrolase. It catalyses the following reaction:
N-acetylgalactosamine-6-sulfatase is an enzyme that, in humans, is encoded by the GALNS gene.
N-acetylglucosamine-6-sulfatase (EC 3.1.6.14, glucosamine (N-acetyl)-6-sulfatase, systematic name N-acetyl-D-glucosamine-6-sulfate 6-sulfohydrolase) is an enzyme that in humans is encoded by the GNS gene. It is deficient in Sanfilippo Syndrome type IIId. It catalyses the hydrolysis of the 6-sulfate groups of the N-acetyl-D-glucosamine 6-sulfate units of heparan sulfate and keratan sulfate
In enzymology, a choline sulfotransferase is an enzyme that catalyzes the chemical reaction
Estrone sulfotransferase (EST), also known as estrogen sulfotransferase, is an enzyme that catalyzes the transformation of an unconjugated estrogen like estrone into a sulfated estrogen like estrone sulfate. It is a steroid sulfotransferase and belongs to the family of transferases, to be specific, the sulfotransferases, which transfer sulfur-containing groups. This enzyme participates in androgen and estrogen metabolism and sulfur metabolism.
In enzymology, a N-sulfoglucosamine sulfohydrolase (EC 3.10.1.1), otherwise known as SGSH, is an enzyme that catalyzes the chemical reaction
In enzymology, a phosphoadenylylsulfatase (EC 3.6.2.2) is an enzyme that catalyzes the chemical reaction
The enzyme chondro-4-sulfatase (EC 3.1.6.9) catalyzes the reaction
In enzymology, a glucuronate-2-sulfatase is an enzyme that catalyzes the chemical reaction of cleaving off the 2-sulfate groups of the 2-O-sulfo-D-glucuronate residues of chondroitin sulfate, heparin and heparitin sulfate.
The enzyme N-acetylgalactosamine-6-sulfatase catalyzes the chemical reaction of cleaving off the 6-sulfate groups of the N-acetyl-D-galactosamine 6-sulfate units of the macromolecule chondroitin sulfate and, similarly, of the D-galactose 6-sulfate units of the macromolecule keratan sulfate.
In enzymology, a galactose-6-sulfurylase is an enzyme that catalyzes the chemical reaction
Sulfatase-modifying factor 1 is an enzyme that in humans is encoded by the SUMF1 gene.
Sulfate conjugates are a heterogeneous class of polar, anionic organosulfate compounds containing an ester of sulfuric acid. Sulfate conjugates commonly result from the metabolic conjugation of endogenous and exogenous compounds with sulfate (-OSO3−).
