ENTRY       EC 2.7.7.10
NAME        UTP--hexose-1-phosphate uridylyltransferase
            Galactose-1-phosphate uridylyltransferase
CLASS       Transferases
            Transferring phosphorus-containing groups
            Nucleotidyltransferases
SYSNAME     UTP:alpha-D-hexose-1-phosphate uridylyltransferase
REACTION    UTP + alpha-D-Galactose 1-phosphate = Pyrophosphate + UDPgalactose
SUBSTRATE   UTP
            alpha-D-Galactose 1-phosphate
            alpha-D-Glucose 1-phosphate
PRODUCT     Pyrophosphate
            UDPgalactose
            UDPglucose
COMMENT     alpha-D-Glucose 1-phosphate can also act as acceptor, more slowly.
