Pirin Transcriptionally Regulates PLA2G4A To Inhibit Ferroptosis in Colorectal Cancer via Lipid Profile Remodeling

Advanced Science, EarlyView.
This study identifies Pirin (PIR), an iron‐binding protein, as a critical ferroptosis suppressor in colorectal cancer through lipid membrane remodeling. PIR, induced by NRF2 during ferroptotic stress, transcriptionally regulates PLA2G4A to shift cellular lipid composition away from ferroptosis‐permissive polyunsaturated phospholipids.

Nonheme Fe Enzyme‐Catalyzed Enantiodivergent Nitrogen Migration: Directed Evolution and Computational Study of Isopenicillin N Synthases for Biocatalytic Synthesis of Arylglycines

Angewandte Chemie, EarlyView.
Nonheme Fe enzyme isopenicillin N synthase was reprogrammed and evolved as an efficient nitrogen migratase IPNSNim, converting diverse azanyl esters to valuable l‐arylglycines with up to 16 000 TTN and 97:3 e.r. IPNSNim and ACCONim allowed enantiodivergent preparation of both l‐ and d‐arylglycines.

Inhibitors of both the N-methyl lysyl- and arginyl-demethylase activities of the JmjC oxygenases

Philosophical Transactions of the Royal Society B: Biological Sciences, 2018
The Jumonji C (JmjC) family of 2-oxoglutarate (2OG)-dependent oxygenases have established roles in the regulation of transcription via the catalysis of demethylation of Nε-methylated lysine residues in histone tails, especially the N-terminal tail of ...

CRISPLD2 Attenuates Intervertebral Disc Degeneration by Suppressing Oxidative Stress‐Induced Ferroptosis through the miR‐548I‐IL17A Axis

Advanced Science, EarlyView.
This study identifies CRISPLD2 as a key protector against IVDD. By regulating ferroptosis through the CRISPLD2–miR‐548I–IL17A axis, CRISPLD2 maintains NPCs homeostasis and reduces oxidative stress. Restoring CRISPLD2 expression effectively alleviates disc degeneration and highlights a promising therapeutic strategy for discogenic low back pain ...

Unexpected Dual Function of Plant YUCCA Enzymes Links Chlorophyll Catabolism to Auxin Homeostasis

Angewandte Chemie, EarlyView.
YUCCA enzymes are well known to catalyze the main step of auxin biosynthesis in plants. Here, a hitherto undescribed dual function was discovered, revealing that some YUCCAs also act in chlorophyll degradation. In vitro feedback regulation furthermore suggests a link between chlorophyll degradation and hormone homeostasis and a physiological role of ...

Human AlkB homologue 5 is a nuclear 2-oxoglutarate dependent oxygenase and a direct target of hypoxia-inducible factor 1α (HIF-1α).

PLoS ONE, 2011
Human 2-oxoglutarate oxygenases catalyse a range of biological oxidations including the demethylation of histone and nucleic acid substrates and the hydroxylation of proteins and small molecules.

Heme-oxygenases during erythropoiesis in K562 and human bone marrow cells. [PDF]

PLoS ONE, 2011
In mammalian cells, heme can be degraded by heme-oxygenases (HO). Heme-oxygenase 1 (HO-1) is known to be the heme inducible isoform, whereas heme-oxygenase 2 (HO-2) is the constitutive enzyme.

Expression of mRNA for phospholipase A(2), cyclooxygenases, and lipoxygenases in cultured human umbilical vascular endothelial and smooth muscle cells and in biopsies from umbilical arteries and veins [PDF]

, 1998
Arachidonic acid (AA) is released by phospholipase A(2) (PLA(2)) and then converted into vasoactive and inflammatory eicosanoids by cyclooxygenases (COX) and lipoxygenases (LOX).

Complementary Steric Engineering at the Protein-Ligand Interface for Analogue-Sensitive TET Oxygenases.

Journal of the American Chemical Society, 2018
Ten-eleven translocation (TET) enzymes employ O2, earth-abundant iron, and 2-ketoglutarate (2KG) to perform iterative C-H oxidation of 5-methylcytosine in DNA to control expression of the mammalian genome.
