General description

Research area: Cell Signaling

Galactose-1-phosphate uridyltransferase (GALT) is a galactose metabolizing enzyme that facilitates the simultaneous conversion of uridine diphosphoglucose (UDP-glucose) and galactose-1-phosphate (gal-1P) to uridine diphosphogalactose (UDP-galactose) and glucose-1-phosphate. Classic Galactosemia (CG) is an inherited metabolic condition caused by deficiency of GALT activity.[1] GALT gene is mapped to human chromosome 9p13. Deficiency of GALT results in type 1 galactosemia.[1]

Application

Galactose-1-phosphate Uridyltransferase from galactose-adapted yeast has been used to perform enzyme assays.

Physical form

Contains buffer salts as citrate and reduced glutathione

Other Notes

One unit will form 1.0 μmole of glucose 1-phosphate from UDP-glucose, galactose 1-phosphate and NADP+ per min at pH 8.7 at 25 °C as detected by a coupled system using phosphoglucomutase.

Classical galactosaemia is relatively common in Ireland due to a high carrier rate of the Q188R GALT mutation. It is screened for using a bacterial inhibition assay (BIA) for free galactose. A Beutler assay on day one of life is

All monodeoxygenated galactoses were treated with galactokinase, and for the 2-, 3-, and 4-deoxy compounds, transformation into the corresponding galactopyranosyl phosphates could be observed. In case of the 2-deoxy derivative, further reaction via UDP-2-deoxy-D-lyxo-hexose (UDP-2-deoxygalactose), which was also obtained chemically

The Cucurbitaceae translocate a significant portion of their photosynthate as raffinose and stachyose, which are galactosyl derivatives of sucrose. These are initially hydrolyzed by alpha-galactosidase to yield free galactose (Gal) and, accordingly, Gal metabolism is an important pathway in Cucurbitaceae

Classic galactosemia is an autosomal recessive inherited error of galactose metabolism. It is caused by lack of galactose-1-phosphate uridyl transferase, an enzyme that is required to metabolize galactose-1-phosphate to uridine diphosphate galactose. The build up of galactose-1-phosphate is toxic at
