Protein
Anti-sigma-E factor ChrR
Organism
Rhodobacter sphaeroides (strain ATCC 17023 / 2.4.1 / NCIB 8253 / DSM 158)
Function
Anti-sigma factor that inhibits the activity of the extracytoplasmic function (ECF) sigma-E factor (RpoE), thereby indirectly regulating the transcription of the cycA and rpoE genes. ECF sigma factors are held in an inactive form by a cognate anti-sigma factor.
Similarity
Belongs to the zinc-associated anti-sigma factor (ZAS) superfamily.
