The mechanisms of carbon catabolite repression in bacteria
Current Opinion in Microbiology, 2008Carbon catabolite repression (CCR) is the paradigm of cellular regulation. CCR happens when bacteria are exposed to two or more carbon sources and one of them is preferentially utilised (frequently glucose). CCR is often mediated by several mechanisms, which can either affect the synthesis of catabolic enzymes via global or specific regulators or ...

Induction and catabolite repression mechanisms of cellulase in fungi
Journal of Bioscience and Bioengineering, 2001Cellulases are induced in most of fungi only when cellulose or an inducer exists. In Hypocrea jecorina and Penicillium purpurogenum, the respective inducers are sophorose and gentiobiose, which do not have beta-1,4 linkages though cellobiose, which has this linkage, is an inducer in other fungi.

Catabolite repression in Bacillus subtilis
Biochimica et Biophysica Acta (BBA) - General Subjects, 1978Abstract The d -gluconate transport system of Bacillus subtilis is optimally induced by exposure of cells for 2 h to 5 mM d -gluconate in the growth medium. d -gluconate transport is subject to catabolite repression, as distinct from inducer exclusion or catabolite inhibition, in a manner parallel to the repression of inducible histidase ...

Nitrogen Catabolite Repression in members of Paracoccidioides complex
Microbial Pathogenesis, 2020Paracoccidioides complex is a genus that comprises pathogenic fungi which are responsible by systemic disease Paracoccidioidomycosis. In host tissues, pathogenic fungi need to acquire nutrients in order to survive, making the uptake of nitrogen essential for their establishment and dissemination.

Catabolite-Induced Repression of Sporulation in Bacillus subtilis
Current Microbiology, 2003In response to nutrient limitations, Bacillus subtilis cells undergo a series of morphological and genetic changes that culminate in the formation of endospores. Conversely, excess catabolites inhibit sporulation. It has been demonstrated previously that excess catabolites caused a decrease in culture medium pH in a process that required functional ...

Catabolite Repression and Physiological Control
2004When confronted with a mixture of potential carbon sources at sufficiently high concentrations, many bacterial species often assimilate the different compounds in an ordered fashion, so that expression of the pathway for the assimilation of the non-preferred substrate remains inhibited until the preferred one is consumed.

FROM DIAUXIE TO THE CONCEPT OF CATABOLITE REPRESSION
1979The most universally known and the most often misquoted is "Whatever is true for E. coli is true for an elephant." Jacques Monod's faith in the universality of the laws and mechanisms of biology contrasting with his provocative attitude of apparent cynicism in front of the great problems of "the secrets of life" was fascinating to those of us who ...
