One of such enzymes is galactose-1-phosphate uridylytransferase (GALT). The enzyme catalyzes the transfer of a UDP-activator group from UDP-glucose to galactose-1-phosphate.
A specific enzyme involved in this process is galactose-1-phosphate uridylyltransferase (GALT), which enables the transfer of a UDP-activating moiety from UDP-glucose to galactose-1-phosphate.
