Recombinant Human Galactose mutarotase (GALM)

Uniprot Id

Q96C23

Target Species

Human

Target Name

GALM

Target Full Name

Galactose mutarotase

Target Function

Mutarotase that catalyzes the interconversion of beta-D-galactose and alpha-D-galactose during galactose metabolism. Beta-D-galactose is metabolized in the liver into glucose 1-phosphate, the primary metabolic fuel, by the action of four enzymes that constitute the Leloir pathway: GALM, GALK1 (galactokinase), GALT (galactose-1-phosphate uridylyltransferase) and GALE (UDP-galactose-4'-epimerase). Involved in the maintenance of the equilibrium between the beta- and alpha-anomers of galactose, therefore ensuring a sufficient supply of the alpha-anomer for GALK1. Also active on D-glucose although shows a preference for galactose over glucose.

Target Background

This gene encodes an enzyme that catalyzes the epimerization of hexose sugars such as glucose and galactose. The encoded protein is expressed in the cytoplasm and has a preference for galactose. The encoded protein may be required for normal galactose metabolism by maintaining the equilibrium of alpha and beta anomers of galactose.
