Conclusion It is known since some time that regulatory redox switches control sulfur allocation between the primary and secondary routes of sulfur assimilation in Arabidopsis and other plants, notably under oxidative stress conditions during which there is an increased demand for reduced sulfur to support cysteine and glutathione synthesis
The GHK sequence itself is naturally present in collagen and SPARC (Secreted Protein Acidic and Rich in Cysteine) protein, suggesting it functions as an emergency response molecule released during tissue injury through protein breakdown
