What is Galactose 1 Phosphate Uridyltransferase (GALT)?
Galactose 1 Phosphate Uridyltransferase (GALT) is an enzyme encoded by the GALT gene. This enzyme plays a critical role in the metabolism of galactose, a simple sugar that is a component of lactose. Specifically, GALT catalyzes the conversion of galactose-1-phosphate and UDP-glucose into UDP-galactose and glucose-1-phosphate, a key step in the Leloir pathway of galactose metabolism.
