Investigation of carbon catabolite repression in Clostridium beijerinckii NCIMB 8052
… utilization of these substrates is subject to carbon catabolite repression. In Gram-positive bacteria, carbon catabolite repression is controlled by a global regulatory mechanism, central to which is an imperfect palindromic sequence, the cre element, which is recognized by a protein of the …

Distribution of proteins involved in carbon catabolite repression in Aspergillus nidulans.
Carbon catabolite repression (CCR) is a mechanism by which micro-organisms preferentially utilize more easily metabolizable carbon sources in comparison to less easily metabolizable carbon sources. It prevents the organisms from unnecessary expenditure of energy and enables them to exploit the …

Characterization of the Components of Carbon Catabolite Repression in Clostridium perfringens
… process in C. perfringens is subject to carbon catabolite repression (CCR) by sugars, especially glucose. CCR is a regulatory pathway that alters transcription based on carbon source availability. In Gram-positive bacteria, the HPr kinase/phosphatase is responsible for this nutritional …

CcpA-Mediated Carbon Catabolite Repression of Virulence in the Group A Streptoccus
… primary mediator of sugar metabolism regulation, carbon catabolite control protein (CcpA), in the regulation of virulence of the GAS. A putative CcpA-binding site or catabolite response element (cre) was identified upstream of the promoter for the virulence gene regulator, Mga. CcpA was shown to …

Carbon Catabolite Repression Relaxation: Approaches for Sugar Co-Utilization in Escherichia coli
… is complicated with Escherichia coli due to carbon catabolite repression (CCR), an intrinsic sugar preference system. The relaxation of the effects of CCR has the possibility to increase bioprocessing’s economic viability and sustainability through better feedstock utilization. In this work …

The cloning and preliminary characterization of the creA gene from Aspergillus nidulans / by Celia E.A. Dowzer.
… as a negatively acting regulatory protein in carbon catabolite repression.

Investigation of global regulators influencing styrene metabolism and bioplastic synthesis in Pseudomonas putida CA-3
… a reduced sensitivity to the effects of carbon catabolite repression of aromatic pathway activity. Our efforts identified a clpX disrupted mutant which exhibited wild-type levels of growth on styrene but significantly reduced growth on phenylacetic acid. RT-PCR analysis of key PACoA …

An investigation of the role of CreB deubiquitinating enzyme in the regulation of carbon metabolism in Aspergillus nidulans
In A. nidulans, carbon catabolite repression is regulated by the global repressor protein CreA which, in the presence of repressing carbon sources, represses those genes that are required to utilize less preferable carbon sources. Mutational analyses suggested that ubiquitination, mediated by CreD …

Estrategias de uso de Saccharomyces cerevisiae en fermentaciones aeróbicas
… the relationship between the flexibilization of carbon catabolite repression (ability to consume secondary sugars in the presence of glucose) and lower acetic acid production, which serves as the basis for the design of a directed evolution to obtain strains with low acetic acid production in …

The Regulation of NAP4 in Saccharomyces cerevisiae
… is known to be transcriptionally controlled by carbon sources. However, little is known about Hap4 regulation. In this report, I identify mechanisms by which Hap4 is regulated, including: (1) transcriptional regulation via two short upstream open reading frames (uORFs) in the 5' leader sequence …
