Protein attributes

Sequence length	1193 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Component of the DNA-dependent RNA polymerase that catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Second largest component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Proposed to contribute to the polymerase catalytic activity and forms the polymerase active center together with the largest subunit By similarity.
Catalytic activity	Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1).
Sequence similarities	Belongs to the RNA polymerase beta chain family.
