LITERATURE
at pH 4.0, the bacterium augments enzyme production in the presence of glutamine (about 10 mM) in the medium, which predominantly occurs after a 6-min time-lag
exposure to cadmium increases the activities of both gammaglutamyl transferase and glutathione transferase 2
-
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
the VvGGT3 transcript in whole berries is upregulated upon Botrytis cinerea infection as well as mechanical damage to leaf tissue. In comparison to Botrytis infection, there is only a mild about 2.0fold increase in the relative transcript abundance of VvGGT3in mechanically wounded leaves compared to the unwounded control leaves at 6 h post wounding beacoming significantly different after 12 h
tumor necrosis factor TNFalpha induces GGT promoter transactivation, mRNA and protein synthesis, as well as enzymatic activity. Remicade, a clinically used anti-TNFalpha antibody, small interfering RNA against p50 and p65 nuclear factor NF-kB isoforms, curcumin, a well characterized natural NF-kB inhibitor, as well as a dominant negative inhibitor IkBa, prevent GGT activation at various levels. Over-expression of receptor of TNFalpha-1, TNFR-associated factor-2 TRAF2, TNFR-1 associated death domain TRADD, dominant negative IkBa or NF-kB p65 further confirm GGT promoter activation via NF-kB.Mutation of the NF-kB site located at 110 additionally inhibits TNFalpha-induced promoter induction
