    Protein Summary

    Gene Reut_A1011 from Ralstonia eutropha encodes the YP_295234 protein, a probable glutathione S-transferase (GST) showing the N-terminal domain from PF02798 and the C-terminal domain from PF00043. GSTs are enzymes that inactivate toxic compounds by conjugation with glutathione and are involved in resistance towards drugs, antibiotics, insecticides and herbicides.

    pre-SCOP classifies 3cbu N-terminal domain in the alpha/beta class, thioredoxin-like superfamily, GST N-terminal domain family; and the C-terminal domain in the all alpha class, GST C-terminal domain like (super)family. DALI top hits are with GSTs like PDB:3lxz (Z=29), PDB:1v2a (Z=22), PDB:1fw1 (Z=21).

    3cbu structure forms a dimer and contains unmodeled density in the putative active site; however, it is not possible to model glutathione or one of its derivatives in the density.

    Reut_A1011 has 29% seq. id. with the GST-III from the plant Zea mays var. mutin. Like other theta-class GSTs, 3cbu contains a conserved serine residue at position 10, which is proposed to be the main catalytic residue for all theta-class GSTs.
