PF04552 | Sigma-54, DNA binding domain (Sigma54_DBD) | Sigma-54, DNA binding domain | 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 r ... | Domain |
