Abstract
A thiol-specific antioxidant(TSA) protein was purified from Earthworm, Lumbricus terrestris by DEAE-Cellulose, Phenl sepharose, Sephacryl S-200 gel filtration and HPLC S-300 Column Chromatography. This protein showed a thiol-specific antioxidant activity against inactivation of glutamine synthetase by a metal-catalysed oxidation system capable of generation reaction oxygen species. The molecular mass of the protein was determinated to be 51-kDa by SDS-polyacrylamide gel electrophores. Taken together, the purified TSA protein could be a new member of TSA family.
