Antioxidation and symbiotic nitrogen fixation function of prxA gene in Mesorhizobium huakuii

MicrobiologyOpen, 2019
Peroxiredoxins (Prxs) play an essential role in the antioxidant activity and symbiotic capacity of Mesorhizobium huakuii. A mutation in the M. huakuii prxA gene (encoding a Prx5‐like peroxiredoxin) was generated by homologous recombination.

Identification, Expression, and Regulation of an Omega Class Glutathione S-transferase in Rhopalosiphum padi (L.) (Hemiptera: Aphididae) Under Insecticide Stress

Frontiers in Physiology, 2018
Glutathione S-transferases (GSTs) play an essential role in the detoxification of xenobiotic toxins in insects, including insecticides. However, few data are available for the bird cherry-oat aphid, Rhopalosiphum padi (L.).

Selective decomposition of cumene hydroperoxide into phenol and acetone by a novel cesium substituted heteropolyacid on clay

, 2003
Phenol is industrially produced by the Hock process starting from benzene and propylene to yield cumene, which is subsequently oxidized with oxygen to generate cumene hydroperoxide (CHP) which is then decomposed with sulfuric acid to obtain equimolar ...

Mutations Selectively Evolving Peroxidase Activity Among Alternative Catalytic Functions of Human Glutathione Transferase P1-1

Antioxidants
Glutathione transferases are detoxication enzymes with broad catalytic diversity, and small alterations to the protein’s primary structure can have considerable effects on the enzyme’s substrate selectivity profile.
