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 ...
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 ...
The lac operon genes are expressed to digest the available lactose until this sugar is depleted, at which point the operon shuts down. However, the lac operon was far from solved. “ [It] turned out ...
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 ...
