Enzyme reactions

• Enzyme class: E.C.2.7.1.6 - galactokinase.
• Reaction: alpha-D-galactose + ATP = alpha-D-galactose 1-phosphate + ADP + H⁺

alpha-D-galactose (Bound ligand (Het Group name = GLA) corresponds exactly) + ATP = alpha-D-galactose 1-phosphate (Bound ligand (Het Group name = MAP) matches with 78.79% similarity) + ADP + H(+)
