FunFam 433: Estrogen sulfotransferase

There are 5 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Aryl sulfotransferase. [EC: 2.8.2.1]
3'-phosphoadenylyl sulfate + a phenol = adenosine 3',5'-bisphosphate + an aryl sulfate.
  • A number of aromatic compounds can act as acceptors.
  • Organic hydroxylamines are not substrates (cf. EC 2.8.2.9).

Estrone sulfotransferase. [EC: 2.8.2.4]
3'-phosphoadenylyl sulfate + estrone = adenosine 3',5'-bisphosphate + estrone 3-sulfate.

    Bile-salt sulfotransferase. [EC: 2.8.2.14]
    (1) 3'-phosphoadenylyl sulfate + glycolithocholate = adenosine 3',5'-bisphosphate + glycolithocholate 3-sulfate. (2) 3'-phosphoadenylyl sulfate + taurolithocholate = adenosine 3',5'-bisphosphate + taurolithocholate sulfate.
    • The formation of sulfate esters of bile acids is an essential step in the prevention of toxicity by monohydroxy bile acids in many species.
    • This enzyme is both a bile salt and a 3-hydroxysteroid sulfotransferase.
    • In addition to the 5-beta-bile acid glycolithocholate, deoxycholate, 3-beta-hydroxy-5-cholenoate and dehydroepiandrosterone (3-beta- hydroxyandrost-5-en-17-one) also act as substrates (see also EC 2.8.2.2 and EC 2.8.2.34).
    • May be identical to EC 2.8.2.2.

    Alcohol sulfotransferase. [EC: 2.8.2.2]
    3'-phosphoadenylyl sulfate + an alcohol = adenosine 3',5'-bisphosphate + an alkyl sulfate.
    • Primary and secondary alcohols, including aliphatic alcohols, ascorbate, chloramphenicol, ephedrine and hydroxysteroids, but not phenolic steroids, can act as acceptors (cf. EC 2.8.2.15).

    Amine sulfotransferase. [EC: 2.8.2.3]
    3'-phosphoadenylyl sulfate + an amine = adenosine 3',5'-bisphosphate + a sulfamate.
    • A large number of primary and secondary amines can act as acceptors, including aniline, 2-naphthylamine, cyclohexylamine and octylamine.
