RNA polymerase-binding protein DksA; The model that is the basis for this family describes a small, pleiotropic protein, DksA (DnaK suppressor A), originally named as a multicopy suppressor of temperature sensitivity of dnaKJ mutants. DksA mutants are defective in quorum sensing, virulence, etc. DksA is now understood to bind RNA polymerase directly and modulate its response to small molecules to control the level of transcription of rRNA. Nearly all members of this family are in the Proteobacteria. Whether the closest homologs outside the Proteobacteria function equivalently is unknown. The low value set for the noise cutoff allows identification of possible DksA proteins from outside the proteobacteria. TIGR02419 describes a closely related family of short sequences usually found in prophage regions of proteobacterial genomes or in known phage.

regulatory protein, yteA family; Members of this predicted regulatory protein are found only in endospore-forming members of the Firmicutes group of bacteria, and in nearly every such species; Clostridium perfringens seems to be an exception. The member from Bacillus subtilis, the model system for the study of the sporulation program, has been designated both yteA and yzwB. Some (but not all) members of this family show a strong sequence match to Pfam family pfam01258 the C4-type zinc finger protein, DksA/TraR family, but only one of the four key Cys residues is conserved. All members of this protein family share an additional C-terminal domain. Smaller proteins from the proteobacteria with just the N-terminal domain, including DksA and DksA2 are RNA polymerase-binding regulatory proteins even if the Zn-binding site is not conserved.
