Intermolecular Carbon–Carbon Naphthalene Coupling Involves a Radical Mechanism Driven by Cytochrome P450 in Alternaria alternata

open access: yesAngewandte Chemie, EarlyView.
1,8‐DHN is an important intermediate to form complex aromatic ring systems. Phenol‐coupling reactions are important for the dimerization of two molecules. Here, we show that a fungal cytochrome P450 enzyme catalyzes specific C─C bonds. ABSTRACT Dihydroxynaphthalene (DHN) derivatives are precursors of biologically important molecules, including melanin ...

A Review of the Effects of Curcumin on Histone Acetyltransferase Activity in the Prevention of Cardiac Hypertrophy

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2017
BACKGROUND AND OBJECTIVE: Curcumin, a natural polyphenolic compound derived from the rhizome of turmeric, has a cardiovascular protective effects. Histone acetyltransferase (HAT) is a consequential enzyme in processes of cardiac hypertrophy (cardiomegaly)

CBP/p300 lysine acetyltransferases inhibit HIV-1 expression in latently infected T cells

open access: yesiScience
Summary: HIV-1 latency is regulated by chromatin modifying enzymes, and histone deacetylase inhibitors (HDACi) cause reactivation of provirus expression.

Identification and characterization of two types of amino acid-regulated acetyltransferases in actinobacteria

open access: yes, 2017
One hundred and fifty GCN5-like acetyltransferases with amino acid-binding (ACT)-GCN5-related N-acetyltransferase (GNAT) domain organization have been identified in actinobacteria. The ACT domain is fused to the GNAT domain, conferring amino acid-induced

How do histone acetyltransferases select lysine residues in core histones? [PDF]

open access: yes, 1998
Acetylation of specific lysines of core histone N-terminal tails correlates with chromatin assembly and specific regulation of gene expression. Core histones acetylated at particular lysines mediate effects on chromatin function; however, the manner in ...

Aspirin‐Derived Salicyl‐CoA Drives Histone Lysine Salicylation Regulated by CBP and SIRT2

open access: yesAdvanced Science, EarlyView.
Aspirin‐derived salicyl‐CoA serves as a previously unrecognized acyl donor for protein lysine salicylation. This study identifies histone lysine salicylation as a reversible epigenetic modification regulated by CBP and SIRT2, expanding the biochemical actions of aspirin beyond its canonical acetylation‐dependent mechanisms and providing a new framework

Structural studies of the prokaryotic arylamine n-acetyltransferases

open access: yes, 2005
The arylamine iV-acetyltransferases (NATs) catalyse the transfer of an acetyl group from the co-factor acetyl CoenzymeA (acetyl CoA) onto the temiinal nitrogen of a range of arylamine and arylhydrazine compounds, including the anti-tubercular agent ...

SCTR–Expressing Astrocyte–Serotonergic Neuron Signaling Drives Sexual Dimorphism in Depression Through KAT7/H4ac–Foxc2 Epigenetic Axis in an AMPK‐Dependent Manner

open access: yesAdvanced Science, EarlyView.
Astrocytic SCTR modulates depressive‐related phenotypes via AMPKα1, whereas lowered Mt1 blunts Megalin‐dependent AMPKα2 signaling in serotonergic neurons. Diminished AMPKα2 hinders KAT7 nuclear translocation, curtails KAT7 occupancy and H4K8ac at the Foxc2 promoter, and represses Foxc2 transcription, revealing cell‐type‐specific AMPK‐linked epigenetic ...

Diabetes Primes Neutrophils for Neutrophil Extracellular Trap Formation through Trained Immunity

open access: yesResearch
Neutrophils are primed for neutrophil extracellular trap (NET) formation during diabetes, and excessive NET formation from primed neutrophils compromises wound healing in patients with diabetes.

ACAT1‐Mediated SP1‐K694 Lactylation Promotes M1 Macrophage Polarization via TREM1 Transcription in COPD

open access: yesAdvanced Science, EarlyView.
Upon cigarette smoke exposure(CSE), LDHA expression is increased in lung macrophages, promoting the conversion of pyruvate to lactate and elevating the lactylation level of SP1 at the K694 site. This, in turn, enhances SP1 enrichment at the TREM1 promoter, increases TREM1 expression, promoted M1 macrophage polarization, and triggers the secretion of ...
