- PMID:22609922; coupled TrxA/TrxB/NADPH assay with no activity when either is omitted; Km(app) for H2O2, CHP and BHP measured.
- PMID:22609922, complemented in trans; not sensitive at 20 mM.
- PhoA/LacZ fusions: probably cytoplasmic, unlike E. coli Tpx PMID:22609922.
- IscR represses tpx; induced by redox-cycling agents and diamide.
- GO:0008379 thioredoxin peroxidase activity is labelled obsolete in current GOA; replaced here by GO:0140824 thioredoxin-dependent peroxiredoxin activity (substrate breadth shown), following the precedent in genes/XANCP/Q8P365.

No PseudoCAP defects. One GO_CENTRAL defect (OUTDATED_STATEMENT, CONFIRMED): the PTN002454730 IBD uses the now-obsolete GO:0008379; repoint to GO:0140824. The IBD is otherwise sound.
