Region 4 of sigma-70 like sigma-factors are involved in binding to the -35 promoter element via a helix-turn-helix motif [1]. Due to the way Pfam works, the threshold has been set artificially high to prevent overlaps with other helix-turn-helix families. Therefore there are many false negatives.	Domain

This protein is organized in two domains, an N-terminal beta-sheet-rich domain and a C-terminal alpha-helical domain, which are connected by a linker-alpha-helix on the surface of gp67 opposite the interaction surface. This entry includes the C- terminal domain and the helical linker [1].	Domain
