1.11.1.27 additional information DTT is not a physiological reductant and thioredoxin, the reductant that is active in the catalytic cycle for the 2-Cys peroxiredoxins, is not effective as a reductant for 1-Cys Prdx6. Prdx6 binds and reduces phospholipid hydroperoxides. Prdx6 reduces H2O2 and other short chain hydroperoxides. The conserved Cys in Prdx6 is buried at the base of a narrow pocket. This location renders it unable to dimerize through disulfide formation in the native configuration but homodimers (and multimers) can arise through hydrophobic interactions. Disulfide formation may occur with denatured proteins and heterodimerization also occurs normally as part of the catalytic cycle. The protein also contains a surface expressed catalytic triad, S-D-H, that is important for phospholipid binding and enzymatic activities Mus musculus ?
