RL Submitted (MAY-2017) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the transfer of the gamma-phosphate of ATP to D-
CC galactose to form alpha-D-galactose-1-phosphate (Gal-1-P).
CC {ECO:0000256|HAMAP-Rule:MF_00246}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=alpha-D-galactose + ATP = ADP + alpha-D-galactose 1-phosphate
CC + H(+); Xref=Rhea:RHEA:13553, ChEBI:CHEBI:15378, ChEBI:CHEBI:28061,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:58336, ChEBI:CHEBI:456216; EC=2.7.1.6;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00246};
CC -!- PATHWAY: Carbohydrate metabolism; galactose metabolism.
CC {ECO:0000256|ARBA:ARBA00004947, ECO:0000256|HAMAP-Rule:MF_00246}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00246}.
CC -!- SIMILARITY: Belongs to the GHMP kinase family. GalK subfamily.
CC {ECO:0000256|ARBA:ARBA00006566, ECO:0000256|HAMAP-Rule:MF_00246}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
