The regulation of the Saccharomyces cerevisiae GAL genes in response to galactose as a source of carbon has served as a paradigm for eukaryotic transcriptional control over the last 50 years. Three proteins--a transcriptional activator (Gal4p), an inhibitor (Gal80p), and

Recently, we have demonstrated a predominant association of Rad26p with the coding sequences but not promoters of several GAL genes following transcriptional induction. Here, we show that the occupancy of histone H2A-H2B dimer at the coding sequences of these genes

A wealth of genetic information and some biochemical analysis have made the GAL regulon of the yeast Saccharomyces cerevisiae a classic model system for studying transcriptional activation in eukaryotes. Galactose induces this transcriptional switch, which is regulated by three proteins:

Galactokinase (GalK), particularly GalK from Escherichia coli, has been widely employed for the synthesis of sugar-1-phosphates. In this study, a GalK from Bifidobacterium infantis ATCC 15697 (BiGalK) was cloned and over-expressed with a yield of over 80 mg/L cell cultures.

Galactokinase (GALK, EC 2.7.1.6) is a cytosolic enzyme with a wide occurrence across the taxonomic kingdoms. It catalyzes the phosphorylation of α-d-galactose (Gal) to α-d-Gal-1-P. The cytotoxicity of free (unphosphorylated) Gal is well documented in plants and causes marked defects.
