molecular function
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0016829    lyase activity    Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
    GO:0009024    tagatose-6-phosphate kinase activity    Catalysis of the reaction: ATP + D-tagatose 6-phosphate = ADP + D-tagatose 1,6-bisphosphate.
    GO:0009025    tagatose-bisphosphate aldolase activity    Catalysis of the reaction: D-tagatose 1,6-diphosphate = D-glyceraldehyde 3-phosphate + glycerone phosphate.
biological process
    GO:2001059    D-tagatose 6-phosphate catabolic process    The chemical reactions and pathways resulting in the breakdown of a D-tagatose 6-phosphate.
    GO:0019512    lactose catabolic process via tagatose-6-phosphate    The chemical reactions and pathways resulting in the breakdown of lactose, via the intermediate tagatose-6-phosphate.
    GO:0005988    lactose metabolic process    The chemical reactions and pathways involving lactose, the disaccharide galactopyranosyl-glucose.
    GO:0016310    phosphorylation    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.
