    Glutathione S-transferases (GSTs) are dimeric proteins that play a key role in phase II cellular detoxification. Here, the first crystal structure of a GST class-mu from marine crustacean shrimp Litopenaeus vannamei is reported at a resolution of 2.0 Å. The coordinates reported here have the lowest sequence identity with previously reported GSTs class-mu deposited at the Protein Data Bank (PDB), although they have subtle conformational differences. One key feature of GST class-mu from L. vannamei is the active site crevice markedly reduced when it is compared with other GSTs class-mu. This finding together with the chemical change of residues into the cavity (F112 and Y210) points to a particular specialization in which smallest xenobiotics with nonstandard chemical characteristics can be bound to the H-site. This suggests that marine organisms have evolved structural strategies to provide efficient selectivity toward xenobiotics to be disposed of by the phase II detoxification process.
