The pqiABC operon P1 promoter is paraquat-inducible (superoxide generator-inducible) and SoxRS-regulated; P2 is RpoS-regulated (Koh, 1995; Kim, 2005; Ito, 2008). PqiB has three tandem MCE domains (PF02470) followed by a C-terminal DASH complex subunit Duo1 PF08651-like domain. The pqiAB and yebST genes are paralogous.
