Domain

RNA polymerase Rpo13 subunit HTH domain (IPR021985)

Short name: RNA_pol_Rpo13

Overlapping homologous superfamilies

None.

Domain relationships

None.

Description

This domain is found in archaea, and is about 40 amino acids in length. It has a single completely conserved residue E that may be functionally important. The domain is a 'helix-turn-helix' (HTH) domain in the Rpo13 subunit of the archaeal RNA polymerase [PMID: 19419240]. This domain is involved in downstream DNA binding, and the entire subunit has also been implicated in contacting transcription factor II B.
