    Protein Summary

    Gene mlr4105 from Mesorhizobium loti translates into the putative antioxidant defense protein (NP_105057.1) that belongs to the CMD group (PF02627). ZP_01012034, annotated as alkylhydroperoxidase family core domain protein, has 70% seq. id. with this target.

    SCOP classifies 3c1l inside the all-alpha class, AhpD-like superfamily, Atu0492-like family. According to DALI, structurally similar proteins to 3c1l are the peroxidase related proteins 2pfx (Z=30) and 2oyo (Z=27), the AhpD core protein 2prr (Z=27), the hypothetical proteins ATU0492 2gmy and PA0269 2o4d (Z=17).

    Cys82, Cys85 (and His89) are predicted to be functionally important for the 3c1l putative peroxidase activity. An interesting article describing CMD proteins and relating them to AhpD proteins is given by [Ref].
