As a multifunctional group of enzymes, glutathione S-transferases (GSTs) are capable of inactivation, degradation or excretion of wide range of compounds catalytically or non-catalytically. However, to date, no study has been addresses the presence of GSTs in archaea based on their enzymatic functions. In this study, beside glutathione (GSH) amount measurement, the determination of GST activity in halophilic archaeon called Haloarcula hispanica ATCC 33960 were aimed.
