Question

What is the role of transacetylase in lac operon??​

Answer 1

Answer:

Galactoside acetyltransferase (also known as Galactoside O-acetyltransferase, thiogalactoside transacetylase and GAT) is an enzyme that transfers an acetyl group from acetyl-CoA to galactosides, glucosides and lactosides. It is coded for by the lacA gene of the lac operon in E. coli.

Answer 2

Answer:

Acetyl transferase protect cells from building of toxic product created by Beta-galactosidase acting other galactosides. By acetylating galactosides other than lactose, the transferase prevent Beta-galactosidase from cleaving them.
