    Lac has 3 structural genes Lac Z - It codes for Enzyme b- galactosidase that breaks down the lactose to yield glucose & galactose. This enzymes also converts lactose to allolactose. Lac Y - It codes for Permease which transports lactose into the cell. Lac A - It codes for Transacetylase. This is not essential for lactose metabolism but appears to play a role in detoxification of componds by transfering an acetyl group from Acetyl-CoA to beta -galactosidase.
