SCOP 1.63: Family a.4.5.28: MarR-like transcriptional regulators

Lineage for Family a.4.5.28: MarR-like transcriptional regulators

1. Root: SCOP 1.63

2. Class a: All alpha proteins [46456] (171 folds)

3. Fold a.4: DNA/RNA-binding 3-helical bundle [46688] (11 superfamilies)
   core: 3-helices; bundle, closed or partly opened, right-handed twist; up-and down

4. Superfamily a.4.5: "Winged helix" DNA-binding domain [46785] (36 families)
   contains a small beta-sheet (wing)

5. Family a.4.5.28: MarR-like transcriptional regulators [63379] (5 proteins)
   The N- and C-terminal helical extensions to the common fold form the dimer interface

Proteins:

1. MexR repressor [81686] (1 species)

   • Species Pseudomonas aeruginosa [TaxId:287] [81687] (1 PDB entry)

2. Multiple antibiotic resistance repressor, MarR [68970] (1 species)

   • Species Escherichia coli [TaxId:562] [68971] (1 PDB entry)

3. Pleiotropic regulator of virulence genes, SarA [48292] (1 species)
   closely related to SarR but adopts a different fold; possible experimental artefact?
