GST — Phaseolus vulgaris

Summary

PHAVU_001G002000, designated PvGST, encodes a glutathione S-transferase (GST) belonging to the Phi class, as indicated by its GST_Phi_C and GST_C domains. The enzyme possesses glutathione transferase and glutathione binding activities, and it also exhibits protein homodimerization activity. In French bean, PvGST is associated with detoxification processes, including the breakdown of toxins and response to xenobiotic stimuli, herbicides, and insecticides. It is linked to responses to hydrogen peroxide, salicylate, and auxin signaling, as well as to chlorophyll fluorescence and glutathione metabolism. The protein localizes to the cytoplasm and macromolecular complexes. Studies of related genes in other species connect the GST family to seed size traits, though this has not been established in Phaseolus vulgaris.
