Substrate‐Dependent Crosslinking by the Cytochrome P450 From Aminopyruvatide Biosynthesis

Angewandte Chemie, EarlyView.
Substitutions in the aminopyruvatide precursor peptide altered the C─C linkage formed from a YLY motif by the P450 ApyO to a N─C linkage in a WLY motif. Moreover, constitutional isomers crosslinked by C─C and C─O linkages were formed from YYY or YWY motifs. ABSTRACT Cytochrome P450s catalyze an array of reactions including crosslinking of aromatic side

Compound Abrus cantoniensis Extract Alleviates AFB1‐Induced Liver Injury by Regulating PI3K‐AKT Pathway and Gut Microbiota/Butyrate Metabolism

Advanced Science, EarlyView.
ACCE has a good alleviating effect on AFB1‐induced liver injury, and this alleviating effect is related to the PI3K‐AKT pathway regulated by ACCE and the butyrate metabolism of gut microbiota. ABSTRACT Aflatoxin B1 (AFB1) is a potent hepatotoxin commonly ingested through contaminated food. Abrus cantoniensis Hance, a traditional Chinese medicinal herb,

Intronic polymorphisms of cytochromes P450

Human Genomics, 2010
The cytochrome P450 enzymes active in drug metabolism are highly polymorphic. Most allelic variants have been described for enzymes encoded by the cytochrome P450 family 2 (CYP2) gene family, which has 252 different alleles. The intronic polymorphisms in

Membrane phospholipid augments cytochrome P4501a enzymatic activity by modulating structural conformation during detoxification of xenobiotics. [PDF]

PLoS ONE, 2013
Cytochrome P450 is a superfamily of membrane-bound hemoprotein that gets involved with the degradation of xenobiotics and internal metabolites. Accumulated body of evidence indicates that phospholipids play a crucial role in determining the enzymatic ...

Integration of the D‐Genome Reshapes Gene Transcription, Chromatin Architecture, and Metabolome of Allohexaploid Wheat, Leading to Enhanced Environmental Adaptability

Advanced Science, EarlyView.
Integration of the D‐genome reshapes gene transcription, chromatin architecture, and the metabolome of hexaploid wheat, leading to enhanced adaptability to salt, UV‐B, and alkali stress. ABSTRACT The hybridization‐led integration of the D‐genome into domesticated tetraploid wheat gave rise to allohexaploid wheat, the most cultivated wheat globally ...

Stimulation of OGG1 Enhances Oxidative DNA Damage Repair and Protects Against Acute Liver Failure by Acetaminophen

Advanced Science, EarlyView.
Chemical switching of OGG1 by CMM‐98 accelerates oxidative DNA damage repair and enhances hepatocyte resilience during acetaminophen‐induced acute liver injury. By promoting efficient processing of OGG1‐generated repair intermediates, CMM‐98 reduces oxidative damage, preserves cellular integrity, and protects against acute liver failure, identifying ...
