Answer E. TBP and CBP participate in eukaryotic gene transcription and mRNA translation, respectively. CAP regulates the expression of prokaryotic lactose operons. ACP is involved in fatty add synthesis. [Pg.26]

The well-investigated lactose operon of the bacterium Escherichial coli can be used here as an example of transcriptional control. The lac operon is a DNA sequence that is simultaneously subject to negative and positive control. The operon contains the structural genes for three proteins that are required for the utilization of lactose (one transporter and two enzymes), as well as control elements that serve to regulate the operon. [Pg.118]

The regulation of bacterial transcription is well illustrated by the lactose operon (lac operon) of the colon bacterium Escherichia coli in which the upstream region successively (from the 5 end of the sense strand) includes a promoter (P ) for the gene (I) coding for a repressor protein (the lac repressor), a CRP binding site , the promoter for the lac operon (P), and finally an operator site (O) that prefaces the Z, Y and A structural genes of the operon ... [Pg.340]

Figure 31.3. Operons. (A) The general structure of an operon as conceived by Jacob and Monod. (B) The structure of the lactose operon. In addition to the promoter (p) in the operon, a second promoter is present in front of the regulator gene (/) to drive the synthesis of the regulator. Figure 31.3. Operons.

Some of the known constitutive mutations of the lactose operon occur in the operator sequence rather than the regulator gene. [Pg.559]

The regulation of the in vitro biosynthesis of the N-terminal portion of the jS-D-galactosidase molecule (cx-peptide) of E. coli has been investigated using DNA fragments of the lactose operon as template. ... [Pg.402]

We shall not make a detailed analysis in this section of the extensive factual material in support of the validity of Jacob and Monod s concept of the structure and principles governing regulation of flie lactose operon. This material has recently been examined in many excellent surveys of problems associated with substrate induction of enzymes and the operon (Ames and Martin,... [Pg.86]
