    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: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:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0008251    tRNA-specific adenosine deaminase activity    Catalysis of the reaction: adenosine + H2O = inosine + NH3, in a tRNA molecule.
    GO:0052717    tRNA-specific adenosine-34 deaminase activity    Catalysis of the reaction: adenosine-34 + H2O = inosine-34 + NH3, in a tRNA-Ala molecule.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0008033    tRNA processing    The process in which a pre-tRNA molecule is converted to a mature tRNA, ready for addition of an aminoacyl group.
    GO:0002100    tRNA wobble adenosine to inosine editing    The process in which an adenosine in position 34 of a tRNA is post-transcriptionally converted to inosine.
