The anti-sigma factor RsrA responds to oxidative stress by reburying its hydrophobic core
Counteracting oxidative stress is essential in all organisms. Here, the authors outline a mechanism used by actinomycete bacteria in which oxidation of zinc-binding RsrA blocks its interaction with σR by sequestering hydrophobic residues used to bind σRwithin its own core.
