Carbon catabolite repression in yeast [PDF]
European Journal of Biochemistry, 1992 Control of gene expression is a basic regulatory mechanism of living organisms. In microorganisms, glucose or other rapidly metabolizable carbon sources repress the expression of genes that code for enzymes related to the metabolism of other carbon sources.

Onset of Carbon Catabolite Repression in Aspergillus nidulans [PDF]
Journal of Biological Chemistry, 2003 The role of hexose phosphorylating enzymes in the signaling of carbon catabolite repression was investigated in the filamentous fungus Aspergillus nidulans. A D-fructose non-utilizing, hexokinase-deficient (hxkA1, formerly designated frA1) strain was utilized to obtain new mutants lacking either glucokinase (glkA4) or both hexose kinases (hxkA1/glkA4).

Yeast Carbon Catabolite Repression [PDF]
Microbiology and Molecular Biology Reviews, 1998 SUMMARY Glucose and related sugars repress the transcription of genes encoding enzymes required for the utilization of alternative carbon sources; some of these genes are also repressed by other sugars such as galactose, and the process is known as catabolite repression.

Carbon Catabolite Repression in Yeast is Not Limited to Glucose. [PDF]
Sci Rep, 2019 AbstractCells adapt their gene expression and their metabolism in response to a changing environment. Glucose represses expression of genes involved in the catabolism of other carbon sources in a process known as (carbon) catabolite repression. However, the relationships between “poor” carbon sources is less characterized. Here we show that in addition

Regulation of Hfq by the RNA CrcZ in Pseudomonas aeruginosa carbon catabolite repression. [PDF]
PLoS Genetics, 2014 Carbon Catabolite repression (CCR) allows a fast adaptation of Bacteria to changing nutrient supplies. The Pseudomonas aeruginosa (PAO1) catabolite repression control protein (Crc) was deemed to act as a translational regulator, repressing functions ...

cAMP signaling factors regulate carbon catabolite repression of hemicellulase genes in Aspergillus nidulans [PDF]
AMB Express, 2022 Carbon catabolite repression (CCR) enables preferential utilization of easily metabolizable carbon sources, implying the presence of mechanisms to ensure discriminatory gene repression depending on the ambient carbon sources.

A novel protein kinase that controls carbon catabolite repression in bacteria [PDF]
Molecular Microbiology, 1998 HPr(Ser) kinase is the sensor in a multicomponent phosphorelay system that controls catabolite repression, sugar transport and carbon metabolism in Gram‐positive bacteria. Unlike most other protein kinases, it recognizes the tertiary structure in its target protein, HPr, a phosphocarrier protein of the bacterial phosphotransferase system and a ...

Carbon Catabolite Repression in Bacillus subtilis : Quantitative Analysis of Repression Exerted by Different Carbon Sources [PDF]
Journal of Bacteriology, 2008 ABSTRACT In many bacteria glucose is the preferred carbon source and represses the utilization of secondary substrates. In Bacillus subtilis , this carbon catabolite repression (CCR) is achieved by the global transcription regulator CcpA, whose activity is triggered by the availability of its ...
