An alpha class glutathione S-transferase from pike liver

摘要

Glutathione S-transferase (GST) was isolated from the Esox lucius liver and purified to the homogenous state by SDS-PAGE and isoelectrofocusing. It was found to be a homodimer with a subunit molecular weight of 25235.36 Da (HPLC-MS/MS data) and pI of about 6.4. Its substrate specificity, thermal stability, some kinetic characteristics, and optimum pH were studied. The enzyme was identified as Alpha class GST.
