Glucose repression can be alleviated by reducing glucose phosphorylation rate in Saccharomyces cerevisiae. [PDF]
AbstractMicroorganisms commonly exhibit preferential glucose consumption and diauxic growth when cultured in mixtures of glucose and other sugars. Although various genetic perturbations have alleviated the effects of glucose repression on consumption of specific sugars, a broadly applicable mechanism remains unknown. Here, we report that a reduction in

Effect of Glucose on Endo-xylanase and β-xylosidase Production by Fungi Isolated in Indonesia
Xylanases are widely produced by fungi, and the production of polysaccharide-degrading enzymes, in general, are usually subjected to carbon catabolite repression.

Glucose kinase-dependent catabolite repression in Staphylococcus xylosus [PDF]
By transposon Tn917 mutagenesis, 16 mutants of Staphylococcus xylosus were isolated that showed higher levels of beta-galactosidase activity in the presence of glucose than the wild-type strain. The transposons were found to reside in three adjacent locations in the genome of S. xylosus.

A common bacterial metabolite elicits prion-based bypass of glucose repression [PDF]
Robust preference for fermentative glucose metabolism has motivated domestication of the budding yeast Saccharomyces cerevisiae. This program can be circumvented by a protein-based genetic element, the [GAR+] prion, permitting simultaneous metabolism of ...

Sialidases (neuraminidases) catalyze the removal of terminal sialic acid residues from glycoproteins. Novel enzymes from non-clinical isolates are of increasing interest regarding their application in the food and pharmaceutical industry.

Dynamic patterns of gene expression match extracellular signals through push-pull regulation. [PDF]
Cells can match gene expression to a range of a particular signal. For example, budding yeast expresses at least seven hexose-transporter ([Formula: see text]) genes in different concentration ranges of extracellular glucose. Using time-lapse microscopy,

Candida albicans Hexokinase 2 Challenges the Saccharomyces cerevisiae Moonlight Protein Model
Survival of the pathogenic yeast Candida albicans depends upon assimilation of fermentable and non-fermentable carbon sources detected in host microenvironments.

The nuclear pore complex mediates binding of the Mig1 repressor to target promoters. [PDF]
All eukaryotic cells alter their transcriptional program in response to the sugar glucose. In Saccharomyces cerevisiae, the best-studied downstream effector of this response is the glucose-regulated repressor Mig1.

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 Drosophila gene is subject to glucose repression [PDF]
Amylase-specific cDNA probes were used to assay amylase mRNA levels in third-instar larvae of Drosophila melanogaster . It is shown that there is a difference, of the order of 100-fold, in the mRNA levels between larvae that are fed 10% glucose and larvae of the same wild-type strain that are fed an equivalent diet ...
