Targets and strategies to design soybean seed composition traits

The Plant Genome, Volume 18, Issue 4, December 2025.
Abstract Breeders and geneticists have put great effort into enhancing soybean seed composition and developing elite varieties with desired traits. However, diverse end‐uses and changing consumer preferences present new challenges and opportunities to develop desired compositional profiles for the market.

Small Molecules as Alternate Substrates for 3‐Methylglutaconylation

JIMD Reports, Volume 66, Issue 6, November 2025.
ABSTRACT The leucine catabolism pathway intermediate, trans‐3‐methylglutaconyl (3MGC) CoA, is susceptible to a series of non‐enzymatic reactions that generate organic acid waste products and protein 3MGCylation. These reactions proceed when inborn errors of metabolism (IEM) in HMGCL or AUH lead to enzyme deficiencies. When trans‐3MGC‐CoA levels rise, a

Chiral Polyacetylene‐PDMS‐Copolymer‐Gels as Enantiodifferentiating Alignment Media

Magnetic Resonance in Chemistry, Volume 63, Issue 11, Page 912-926, November 2025.
The crosslinking copolymerization of various amino acid derived 4‐ethinylbenzoic acid amides with different types of diynes delivered polymeric materials that can be used as chiral alignment (SAG) media for the measurement of anisotropic NMR data. Polysiloxane crosslinked gels are particularly suited in this respect.

KAT2A‐H3K79succ‐Mediated SH2B3 Upregulation Promotes TNBC Metastasis Through Diminishing the Ubiquitin‐Dependent Degradation of Vimentin

The FASEB Journal, Volume 39, Issue 20, 31 October 2025.
Lysine acetyltransferase 2A (KAT2A) is a critical catalytic component within transcriptional regulatory complexes and plays a significant role in triple‐negative breast cancer (TNBC). To investigate its underlying mechanism, this study demonstrates that KAT2A catalyzes succinylation at the H3K79 site to promote SH2B3 transcription and enhance its ...

Unveiling Flavonoid Reactivity: A High‐Resolution Mass Spectrometry Journey Through the Silylation of Quercetin

Rapid Communications in Mass Spectrometry, Volume 39, Issue 20, 30 October 2025.
ABSTRACT Rationale Quercetin is an example of a pentahydroxylated flavonol compound studied extensively due to its excellent biological activity (e.g., antioxidant, antiviral, and antimicrobial). The antioxidant properties of flavonoids are influenced by the arrangement of the substituents around the molecule, a phenomenon known as the structure ...

Directing Effects of Silyl and Germyl Groups in Transition‐Metal‐Catalyzed Allylic Substitution

Chemistry – A European Journal, Volume 31, Issue 58, October 16, 2025.
Despite the maturity of transition‐metal‐catalyzed allylic substitution, unsymmetrical 1,3‐disubstituted electrophiles remain underexplored due to inherent regioselectivity challenges. This Concept highlights the strategic use of silyl and germyl groups to overcome this limitation, steering bond formation with high regiocontrol and serving as linchpins

Nucleophilic Acyl Substitution of Acyl Diimides

The Journal of Organic Chemistry, 2009
The nucleophilic acyl substitution of the acyl diimide intermediate formed by the oxidation of isoniazid was found to involve two methanol molecules in a six-membered cyclic transition state. Calculations were performed in the gas phase at the B3LYP/6-311+G(d,p)//B3LYP/6-31G(d) level of theory and solvation effects were included both explicitly and ...

S-Acylation of Proteins [PDF]

, 2019
Palmitoylation or S-acylation is the posttranslational attachment of fatty acids to cysteine residues and is common among integral and peripheral membrane proteins. Palmitoylated proteins have been found in every eukaryotic cell type examined (yeast, insect, and vertebrate cells), as well as in viruses grown in these cells.
