EC 2.8.2.22 Details
EC number
2.8.2.22
Accepted name
aryl-sulfate sulfotransferase
Reaction
an aryl sulfate + a phenol = a phenol + an aryl sulfate
Other name(s)
arylsulfate-phenol sulfotransferase, arylsulfotransferase (ambiguous), ASST, arylsulfate sulfotransferase, arylsulfate:phenol sulfotransferase, astA (gene name), aryl-sulfate:phenol sulfotransferase
Systematic name
aryl-sulfate:phenol sulfonotransferase
CAS registry number
158254-86-5
Comment
The enzyme, characterized from bacteria that colonize the human and mouse intestine, catalyses the transfer of a sulfate group from a phenol sulfate ester to other phenolic compounds. Activity is enhanced by Mg2+ and Mn2+ [1]. Unlike EC 2.8.2.9, tyrosine-ester sulfotransferase and EC 2.8.2.1, aryl sulfotransferase, the enzyme does not act on 3′-phosphoadenylyl sulfate or adenosine 3′,5′-bisphosphate [1].The level of sulfation of polyphenols depends on the positions of the hydroxyl groups [3-5]. Hydroxy groups of tyrosine residues in peptides such as angiotensin can also act as acceptors [2]. The reaction proceeds according to a ping pong bi bi mechanism [6].
