$B$-galactosidase

Vedclass · Answer

(A) In the $lac$ operon of $E. coli$,the $lacZ$ gene codes for the enzyme $B$-galactosidase. This enzyme is responsible for the hydrolysis of the disaccharide lactose into its monomeric units,galactose and glucose. Permease (coded by $lacY$) facilitates the entry of lactose into the cell,and Transacetylase (coded by $lacA$) is involved in the detoxification of the cell,but only $B$-galactosidase performs the specific transformation of lactose into galactose and glucose.

Which enzyme$(s)$ is/are responsible for the transformation of lactose to galactose and glucose in the $E. coli$ culture medium?
