Required for the transport and metabolism of lactose in Escherichia Coli (E. coli).The lactose operon or lac operon consists of three structural genes namely lacZ, lacY, and lacA that encode ...

The Regulation of the lac Operon Gene expression of lactose-digesting genes is controlled by the lac operon that accounts for varying amounts of lactose or glucose in the cell.

Thus, lactose, from which allolactose is formed, induces the expression of the lac operon and of genes required for lactose metabolism.

The lac operon contains what is known as the CAP site, located upstream of the promoter along the DNA. The CAP site gets its name from a protein-the catabolite activator protein-that can bind there.
