5-Aminolevulinic acid (ALA) is the precursor of tetrapyrrole synthesis, and hydrogen sulfide (H2S) a gas signal molecule. Studies have shown that exogenous ALA H2S can alleviate abiotic stress. This study evaluated roles their interactions in regulating antioxidant activity pepper seedlings under chilling Chilling stress significantly inhibited growth increased amounts peroxide (H2O2), superoxi...

Grxs (glutaredoxins) are small ubiquitous redox enzymes. They are generally involved in the reduction of oxidative modifications using glutathione. Grxs are not only able to reduce protein disulfides and the low-molecular-mass antioxidant dehydroascorbate, but also represent the major enzyme class responsible for deglutathionylation reactions. Functional proteomics, including interaction studie...

The glutathione transferases (GSTs) are one of the most important families of detoxifying enzymes in nature. The classic activity of the GSTs is conjugation of compounds with electrophilic centers to the tripeptide glutathione (GSH), but many other activities are now associated with GSTs, including steroid and leukotriene biosynthesis, peroxide degradation, double-bond cis-trans isomerization, ...
