RNA_pol_Rpb2_5

RNA_pol_Rpb2_5
PFAM accession number:PF04567
Interpro abstract (IPR007647): 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 5 is also known as the external 2 domain [(PUBMED:11313498)].
