Functional Annotations

Enzyme classification and Gene Ontology terms linked to this protein.

5 GO

Gene Ontology (GO)

5
  • GO:0008270 Binding to a zinc ion (Zn).
  • GO:0016787 Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc.
  • GO:0009972 OBSOLETE. The removal of amino group in the presence of water.
  • GO:0003824 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:0004126 Catalysis of the reaction: cytidine + H+ + H2O = uridine + NH4 and deoxycytidine + H+ + H2O = deoxyuridine + NH4+.

Ligand evidence

Ligands grouped by evidence source. PDB ligands keep the source crystal visible, and loaded crystals can be opened directly in the structure viewer.

75 records

Structural evidence inferred from similar proteins. The source crystal indicates where the ligand was observed; the UniProt column identifies the homologous protein carrying that ligand.
