Biochem/physiol Actions

Galactokinase catalyzes the phosphorylation of αD-galactose to produce galactose-1-phosphate as part of the Leloir pathway[1].

Physical properties

N-terminal GST-tagged 42 kDa full length protein

Unit Definition

One unit will convert 1.0 picomole of galactose to galactose-1-phosphate per minute at pH 7.4 at 30 °C.

Physical form

Supplied as a solution in 40 mM Tris-HCl, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 20% glycerol, 3 mM DTT and 10-250 mM imidazole.

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

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

Bacterial artificial chromosome (BAC) recombineering using galK selection allows DNA cloned in Escherichia coli to be modified without introducing an unwanted selectable marker at the modification site. Genomes of some herpesviruses have a pair of inverted repeat sequences that makes

Precise targeted mutations are defined as targeted mutations that do not require the retention of other genetic changes, such as marker genes, near the mutation site. In the yeast, S. cerevisiae, there are several methods for introducing precise targeted mutations

Cells have evolved complex regulatory networks that reorganize gene expression patterns in response to changing environmental conditions. These changes often involve redundant mechanisms that affect various levels of gene expression. Here, we examine the consequences of enhanced mRNA degradation in
