RNA_pol_Rpb2_3

RNA_pol_Rpb2_3
PFAM accession number:PF04565
Interpro abstract (IPR007645):

RNA polymerases catalyse the DNA dependent polymerisation of RNA. Prokaryotes contain a single RNA polymerase compared to three in eukaryotes (not including mitochondrial and chloroplast polymerases). Domain 3, is also known as the fork domain and is proximal to catalytic site [ (PUBMED:11313498) ].

GO process:transcription, DNA-templated (GO:0006351)
GO function:DNA binding (GO:0003677), DNA-directed 5'-3' RNA polymerase activity (GO:0003899)
