Expression

Organism Comment Expression
Arabidopsis thaliana isoform GGT2 expression is enhanced in ggt1 knockout mutants, suggesting a compensatory effect to restore enzyme activity in the root apoplast. Supplementation with 0.1 mM glutathione results in the 4fold up-regulation of isoform GGT2 gene expression up
