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 ...

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 ...

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 ...

In support of the view that inducer exclusion is the main factor in diauxie, cAMP–CRP was reported to play a crucial part in diauxie only by activating the transcription of the glucose transporter ...

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 ...
