Superoxide dismutase (SOD) genes encode a family of critical metalloenzymes that serve as a first line of defence against oxidative damage in plants. By converting the superoxide radical into less ...

The formation of superoxide ion radicals (${\mathrm{O}}_{\dot{2}}^{-}$) by chloroplasts from senescing leaves of Phaseolus vulgaris L. was determined by electron-spin-resonance measurements of Tiron ...

Accumulation of misfolded oxidant-damaged proteins is characteristic of many diseases and aging. To understand how cells handle postsynthetically damaged proteins, we studied in Saccharomyces ...
