Metabolism of hydroperoxy-phospholipids in human hepatoma HepG2 cells

Journal of Lipid Research, 1996
Two enzymatic mechanisms have been proposed for the metabolism of hydroperoxy-phospholipids: i) the combined action of phospholipase A2 and glutathione peroxidase, and/or ii) direct enzymatic reduction.

Effect of ochratoxin A and buthionine sulfoximine on proteome and ascorbate-glutathione cycle enzymes in Arabidopsis thaliana

Biologia Plantarum, 2015
In this study, proteome and activities of glutathione (GSH)-related enzymes were investigated in detached leaves of Arabidopsis thaliana treated with ochratoxin A (OTA) alone or supplemented with buthionine sulfoximine (BSO, a specific inhibitor of the ...

Lysine decrotonylation of glutathione peroxidase at lysine 220 site increases glutathione peroxidase activity to resist cold stress in chrysanthemum

Ecotoxicology and Environmental Safety, 2022
Lysine crotonylation is a protein post-translational modification that has been newly discovered in recent years. There are few studies on the lysine crotonylation of proteins in plants, and their functions in response to cold stress are still unclear ...

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.
