Chain A,B,C,D   (RIHB_ECOLI | P33022)
molecular function
    GO:0005509    calcium ion binding    Interacting selectively and non-covalently with calcium ions (Ca2+).
    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:0016799    hydrolase activity, hydrolyzing N-glycosyl compounds    Catalysis of the hydrolysis of any N-glycosyl bond.
    GO:0042802    identical protein binding    Interacting selectively and non-covalently with an identical protein or proteins.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0008477    purine nucleosidase activity    Catalysis of the reaction: a N-D-ribosylpurine + H2O = a purine + D-ribose.
    GO:0050263    ribosylpyrimidine nucleosidase activity    Catalysis of the reaction: an N-D-ribosylpyrimidine + H2O = D-ribose + a pyrimidine.
    GO:0045437    uridine nucleosidase activity    Catalysis of the reaction: H(2)O + uridine = ribofuranose + uracil.
biological process
    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.
    GO:0006152    purine nucleoside catabolic process    The chemical reactions and pathways resulting in the breakdown of purine nucleoside, one of a family of organic molecules consisting of a purine base covalently bonded to a sugar ribose (a ribonucleoside) or deoxyribose (a deoxyribonucleoside).
    GO:0006206    pyrimidine nucleobase metabolic process    The chemical reactions and pathways involving pyrimidine nucleobases, 1,3-diazine, organic nitrogenous bases.
    GO:0046133    pyrimidine ribonucleoside catabolic process    The chemical reactions and pathways resulting in the breakdown of any ribonucleoside, a nucleoside in which a pyrimidine base is linked to a ribose (beta-D-ribofuranose) molecule.
cellular component
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
