    GO ID   Ontology GO Term Definition
    3899   DNA Directed RNA Polymerase Activity  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'. 
    16740   Transferase Activity  Catalysis of the Transfer of a Group E.g. a Methyl Group Glycosyl Group Acyl Group Phosphorus Containing or Other Groups From One Compound (generally Regarded As the Donor) to Another Compound (generally Regarded As the Acceptor). Transferase Is the Systematic Name For Any Enzyme of EC Class 2. 
    16779   Nucleotidyltransferase Activity  Catalysis of the Transfer of a Nucleotidyl Group to a Reactant.
