Carbon metabolism and catabolite repression inRhizobiumspp. [PDF]
The Gram-negative soil bacteria of the family Rhizobiaceae can fonn nodules on the roots of leguminous plants and as a result are able to fix nitrogen. This partnership is highly specific as particular legumes are generally infected by one rhizobial species only (for example alfalfa by R. meliloti and soybean by B. japonicum'i. The establishment of the

Carbon catabolite repression (CCR) is critical for the preferential utilization of glucose derived from environmental carbon sources and regulated by carbon catabolite repressor A (Cre1/CreA) in filamentous fungi.

Carbon catabolite repression of maltase synthesis in Saccharomyces carlsbergensis [PDF]
Carbon catabolite repression of maltase gene expression is brought about by the addition of glucose, resulting in a drastic inhibition of the induction of maltase. When added to induced cells, glucose leads to the inhibition of maltase synthesis within 30 min, which can be accounted for by the disappearance of hybridizable maltase RNA sequences.

In silico evolution of diauxic growth [PDF]
The glucose effect is a well known phenomenon whereby cells, when presented with two different nutrients, show a diauxic growth pattern, i.e. an episode of exponential growth followed by a lag phase of reduced growth followed by a second phase of ...

Evolving strategies for single-celled organisms in multi-nutrient environments [PDF]
When micro-organisms are in environments with multiple nutrients, they often preferentially utilise one first. A second is only utilised once the first is exhausted. Such a two-phase growth pattern is known as diauxic growth.

CcpA Affects Infectivity of Staphylococcus aureus in a Hyperglycemic Environment
Many bacteria regulate the expression of virulence factors via carbon catabolite responsive elements. In Gram-positive bacteria, the predominant mediator of carbon catabolite repression is the catabolite control protein A (CcpA).

Different levels of catabolite repression optimize growth in stable and variable environments.
Organisms respond to environmental changes by adapting the expression of key genes. However, such transcriptional reprogramming requires time and energy, and may also leave the organism ill-adapted when the original environment returns.

Surfactin, a quorum sensing signal molecule, is correlated with carbon metabolism in Bacillus amyloliquefaciens. In the present work, we found that mutation of srfA (ΔsrfA) led to an obviously changed carbon metabolism in B. amyloliquefaciens.

The Pseudomonas aeruginosa CrcZ RNA interferes with Hfq-mediated riboregulation.
The RNA chaperone Hfq regulates virulence and metabolism in the opportunistic pathogen Pseudomonas aeruginosa. During carbon catabolite repression (CCR) Hfq together with the catabolite repression control protein Crc can act as a translational repressor ...
