260829 GalK
Thalassiosira pseudonana

Catalysis of the reaction: D-galactose + ATP = alpha-D-galactose 1-phosphate + ADP + 2 H(+).

Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.

The chemical reactions and pathways involving galactose, the aldohexose galacto-hexose. D-galactose is widely distributed in combined form in plants, animals and microorganisms as a constituent of oligo- and polysaccharides; it also occurs in galactolipids and as its glucoside in lactose and melibiose.

The process of introducing a phosphate group into a carbohydrate, any organic compound based on the general formula Cx(H2O)y.

The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.

Catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule.

Interacting selectively and non-covalently with phosphopantetheine, the vitamin pantetheine 4'-(dihydrogen phosphate).

The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

Catalysis of the transfer of a phosphorus-containing group from one compound (donor) to an alcohol group (acceptor).
