Crystal structures of Streptomyces tsukubaensis sigma factor SigG1 and anti-sigma RsfG

[Display omitted] •Streptomyces tsukubaensis sigma factor SigG1 adopts a compact conformation with σ2, σ4 and the SnoaL_2 domain tightly packed.•Anti-sigma RsfG shows a rare β-barrel fold.•RsfG has a putative Fe(III) binding site that may be associated with the role of the SigG1-RsfG system in metal...
