Unlike GST or MBP, TrxA does not facilitateA Δgor ΔtrxA double mutant (E. coli Δgor/trxA) is no longer able to reduce PAPS red. The introduction of trxA from a plasmid (pCC_trxA) restores PAPS red reduction. B, a Δgor/trxA double mutant is not viable in minimal medium containing sulfate as the sole sulfur source. Expression of E. coli TrxA from plasmid pCC rescues the phenotype.

Strategy IA consisted of phage growth on E. coli BW25113 ∆trxA, which lacks the thioredoxin gene.
