Carbon catabolite repression of the Aspergillus nidulans xlnA gene
Molecular Microbiology, 1999Expression of the Aspergillus nidulans 22 kDa endoxylanase gene, xlnA, is controlled by at least three mechanisms: specific induction by xylan or xylose; carbon catabolite repression (CCR); and regulation by ambient pH. Deletion analysis of xlnA upstream sequences has identified two positively acting regions: one that mediates specific induction by ...

Regulation of catalase synthesis in Saccharomyces cerevisiae by carbon catabolite repression
Molecular and General Genetics MGG, 1978A number of strains of Saccharomyces cerevisiae, wild type or respiratory deficient, were grown on glucose, galactose or raffinose. Specific activities of catalase T were about tenfold higher in late stationary wild type cells grown on glucose than in wild type cells harvested when glucose had just disappeared completely from the medium, or in ...

Starch utilization by yeasts: mutants resistant of carbon catabolite repression
Current Genetics, 1984Twenty-seven yeasts were screened for starch breakdown; the three with the highest rate were strains of Filobasidium capsuligenum, Lipomyces starkeyi and Schwanniomyces occidentalis. Of these, only the last gave mutants with diminished carbon catabolite repression and, hence, enhanced amylase activity.

Carbon Source-Mediated Catabolite Repression
2014Catabolite repression is a regulatory mechanism by which the cell (i) coordinates metabolism of carbon a n d energy sources to maximize efficiency and (ii) regulates other metabolic processes as well. The objective of this review is to examine what is known about the molecular mechanisms by which catabolite repression operates in gram-positive bacteria,

Carbon catabolite repression by the catabolite control protein CcpA in Staphylococcus xylosus.
Journal of molecular microbiology and biotechnology, 2002Carbon catabolic repression (CR) by the catabolite control protein CcpA has been analyzed in Staphylococcus xylosus. Genes encoding components needed to utilize lactose, sucrose, and maltose were found to be repressed by CcpA. In addition, the ccpA gene is under negative autogenous control.

Bacterial Small RNAs (sRNAs) and Carbon Catabolite Repression
2011Bacterial small RNAs (sRNAs) have been shown to play a critical role in regulation of various cellular activities by modulating the expression of key genes and operons. By using highly reliable small RNA prediction tools, the existence of sRNAs is predicted for most bacterial genomes.

A defect in carbon catabolite repression associated with uncontrollable and excessive maltose uptake
Molecular and General Genetics MGG, 1980The previously isolated recessive mutant allele hex2-3 of Saccharomyces cerevisiae caused a defect in carbon catabolite repression of maltase, invertase, malate dehydrogenase, and respiration but at the same time led to an extreme sensitivity to maltose (Zimmerman and Scheel, 1977; Entian and Zimmermann, 1980).

[Advances in mechanism of Escherichia coli carbon catabolite repression].
Yi chuan = Hereditas, 2010Bacteria often sequentially utilize coexisting carbohydrates in environment and firstly select the one (frequently glucose) easiest to metabolize. This phenomenon is known as carbon catabolite repression (CCR). In existing Chinese teaching materials of molecular biology and related courses, unclear or even wrong interpretations are given about CCR ...
