Permease

Vedclass · Answer

(A) In the $lac$ operon of $E. coli$,there are three structural genes: $lac \, z$,$lac \, y$,and $lac \, a$.$1$. The $lac \, z$ gene codes for $\beta$-galactosidase,which is responsible for the hydrolysis of lactose into galactose and glucose.$2$. The $lac \, y$ gene codes for permease,which increases the permeability of the cell to $\beta$-galactosides like lactose.$3$. The $lac \, a$ gene codes for transacetylase.Therefore,the $lac \, y$ gene codes for permease.

The $lac \, y$ gene codes for which of the following?
