We investigated the expression patterns of seven Venerupis philippinarum GSTs （VpGSTs） and four Mytilus galloprovincialis GSTs （MgGSTs） following exposure to BDE-47. Differential expressions of the seven VpGSTs and four MgGSTs transcripts were observed, with differences between the hepatopancreas and gills. Among these GSTs, the sigma classes （VpGSTS1, VpGSTS2, VpGSTS3, MgGST1, and MgGST3） were highly expressed in response to BDE-47 exposure, demonstrating their potential as molecular biomarkers for environmental biomonitoring studies. We obtained the three-dimensional crystal structures of VpGSTs and MgGSTs by homologous modeling.
