Thioethanolamine S-acetyltransferase

Add article description

In enzymology, a thioethanolamine S-acetyltransferase (EC 2.3.1.11) is an enzyme that catalyzes the chemical reaction

acetyl-CoA + 2-aminoethanethiol ⇌ CoA + S-(2-aminoethyl)thioacetate
Quick Facts Identifiers, EC no. ...

Thus, the two substrates of this enzyme are acetyl-CoA and 2-aminoethanethiol, whereas its two products are CoA and S-(2-aminoethyl)thioacetate.

This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is acetyl-CoA:2-aminoethanethiol S-acetyltransferase. Other names in common use include thioltransacetylase B, thioethanolamine acetyltransferase, and acetyl-CoA:thioethanolamine S-acetyltransferase.
