Chain A,B,C,D   (IUNH_LEIMA | P83851)
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:0047724    inosine nucleosidase activity    Catalysis of the reaction: inosine + H2O = D-ribose + hypoxanthine.
    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: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:0009117    nucleotide metabolic process    The chemical reactions and pathways involving a nucleotide, a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the glycose moiety; may be mono-, di- or triphosphate; this definition includes cyclic nucleotides (nucleoside cyclic phosphates).
    GO:0043101    purine-containing compound salvage    Any process that generates a purine-containing compound, any nucleobase, nucleoside, nucleotide or nucleic acid that contains a purine base, from derivatives of them without de novo synthesis.
cellular component
    GO:0005575    cellular_component    The part of a cell, extracellular environment or virus in which a gene product is located. A gene product may be located in one or more parts of a cell and its location may be as specific as a particular macromolecular complex, that is, a stable, persistent association of macromolecules that function together.
