>cd03009 TryX_like_TryX_NRX Tryparedoxin (TryX)-like family, TryX and nucleoredoxin (NRX) subfamily; TryX and NRX are thioredoxin (TRX)-like protein disulfide oxidoreductases that alter the redox state of target proteins via the reversible oxidation of an active center CXXC motif. TryX is involved in the regulation of oxidative stress in parasitic trypanosomatids by reducing TryX peroxidase, which in turn catalyzes the reduction of hydrogen peroxide and organic hydroperoxides. TryX derives reducing equivalents from reduced trypanothione, a polyamine peptide conjugate unique to trypanosomatids, which is regenerated by the NADPH-dependent flavoprotein trypanothione reductase. Vertebrate NRX is a 400-amino acid nuclear protein with one redox active TRX domain containing a CPPC active site motif followed by one redox inactive TRX-like domain. Mouse NRX transcripts are expressed in all adult tissues but is restricted to the nervous system and limb buds in embryos. Plant NRX, longer than the
