	GO:0033920	6-phospho-beta-galactosidase activity	Catalysis of the reaction: a 6-phospho-beta-D-galactoside + H2O = 6-phospho-D-galactose + an alcohol.
	GO:0016787	hydrolase activity	Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
	GO:0016798	hydrolase activity, acting on glycosyl bonds	Catalysis of the hydrolysis of any glycosyl bond.
	GO:0004553	hydrolase activity, hydrolyzing O-glycosyl compounds	Catalysis of the hydrolysis of any O-glycosyl bond.
biological process
	GO:0005975	carbohydrate metabolic process	The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule.
	GO:0005990	lactose catabolic process	The chemical reactions and pathways resulting in the breakdown of lactose, the disaccharide galactopyranosyl-glucose.
	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:0008152	metabolic process	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.
