Galactoside acetyltransferase (also known as Galactoside O-acetyltransferase , thiogalactoside transacetylase , β-galactoside transacetylase and GAT ) is an enzyme that transfers an acetyl group from acetyl-CoA to β-galactosides , glucosides and lactosides. It is coded for by the lacA gene of the lac operonin E. coli [1]
Reaction [ edit ]
It catalyzes the following reaction:
acetyl-CoA + beta-D-galactoside → CoA + 6-acetyl-beta-D-galactoside
The kinetics of the enzyme were delineated in 1995.[2]
Biological role [ edit ]
The enzyme's role in the classical E.coli lac operon remains unclear.[1] [3] [1] [4]
