β-galactoside transacetylase is an enzyme that transfers an acetyl group from acetyl-CoA to β-galactosides, and is coded by a gene (lacA) in the lac operon of E. coli.[1] Its precise function as part of the lac operon is not understood currently.[2]

The kinetics of the enzyme were delineated in 1995.[3]

The enzyme's cellular role may be to detoxify non-metabolizable pyranosides by acetylating them and preventing their reentry into the cell.[4]
