Functional Annotations

Enzyme classification and Gene Ontology terms linked to this protein.

4 GO

Gene Ontology (GO)

4
  • GO:0032549 Binding to a ribonucleoside, a compound consisting of a purine or pyrimidine nitrogenous base linked to ribose.
  • GO:0003677 Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
  • GO:0003899 Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). Utilizes a DNA template, i.e. the catalysis of DNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. Can initiate a chain 'de novo'.
  • GO:0006351 The synthesis of an RNA transcript from a DNA template.

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.

93 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.
