Galactose 1-dehydrogenase (NADP+) explained

galactose 1-dehydrogenase (NADP+)
Ec Number:1.1.1.120
Cas Number:37250-51-4
Go Code:0047910

In enzymology, a galactose 1-dehydrogenase (NADP+) is an enzyme that catalyzes the chemical reaction

D-galactose + NADP+

\rightleftharpoons

D-galactono-1,5-lactone + NADPH + H+

Thus, the two substrates of this enzyme are D-galactose and NADP+, whereas its 3 products are D-galactono-1,5-lactone, NADPH, and H+.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is D-galactose:NADP+ 1-oxidoreductase. Other names in common use include D-galactose dehydrogenase (NADP+), and galactose 1-dehydrogenase (NADP+). This enzyme participates in galactose metabolism.
