Homology structure of delta and sigma class GSTs from <i>L. migratoria</i>.

<p><b>a</b>, Ribbon representation of the 3D-structures of LmGSTD1. <b>b</b>, <b>c</b> Surface representation of LmGSTD1 (<b>b</b> front, <b>c</b> back). <i>N</i>-domain, <i>C</i>-domain and link region are colored yellow, red and green, respectively. The glutathione binding site (G-site), the hydrophobic ligand binding site (H-site) and the positive selective sites are labeled with cyan, orange and blue, respectively. The residues located at the interface of the <i>N</i>- and <i>C</i>-domain are shown in gray. In order to conspicuously display structure details, the homology structure of LmGSTD1 were selected as representative structure of each class in ribbon and surface representation.
