Radiation Research, Vol. 163, No. 4 (Apr., 2005), pp. 433-446 (14 pages) The lactose operon functions under the control of the repressor-operator system. Binding of the repressor to the operator ...

While Jacob, Monod, and others previously showed that lactose metabolites containing galactose residues activated the lac operon, the true inducer remained elusive. 11–13 Then, in 1972, a team ...

The genes lacZ, lacY and lacA are transcribed from a single promoter (P) that produces a single mRNA from which the three proteins are translated. The operon is regulated by Lac repressor, the product ...

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 proteins ...

Carbon catabolite repression (CCR) is a global regulatory mechanism that inhibits the expression and activities of functions for the use of secondary carbon sources when a preferred carbon source is ...
