Domain

RNA polymerase sigma factor 54, DNA-binding (IPR007634)

Short name: RNA_pol_sigma_54_DNA-bd

Domain relationships

None.

Description

This DNA-binding domain is based on peptide fragmentation data. This domain is proximal to DNA in the promoter/holoenzyme complex. Furthermore, this region contains a putative helix-turn-helix motif. At the C terminus, there is a highly conserved region known as the RpoN box and is the signature of the sigma-54 proteins [PMID: 10894718].
