Dereplication of Bioactive Agave Saponin Fractions: The Hidden Saponins
2024 / Journal of Agricultural and Food ChemistryThe good phytotoxicity and selectivity against weeds versus tomato or cress make saponin-rich fractions from Agave macroacantha, A. colorata, A. parryi, and A. parrasana attractive candidates as bioherbicides. The saponin contents have only previously been reported for A. macroacantha, and as a consequence, simultaneous dereplication has been performed on saponin-r...

The Kavaratamides: Discovery of Linear Lipodepsipeptides from the Marine Cyanobacterium Moorena bouillonii Using a Comparative Chemogeographic Analysis
2024 / Journal of Natural ProductsKavaratamide A (1), a new linear lipodepsipeptide possessing an unusual isopropyl-O-methylpyrrolinone moiety, was discovered from the tropical marine filamentous cyanobacterium Moorena bouillonii collected from Kavaratti, India. A comparative chemogeographic analysis of M. bouillonii collected from six different geographical regions led to the prioritized isolation...

De novo design of proteins housing excitonically coupled chlorophyll special pairs
2024 / Nature Chemical BiologyNatural photosystems couple light harvesting to charge separation using a ‘special pair’ of chlorophyll molecules that accepts excitation energy from the antenna and initiates an electron-transfer cascade. To investigate the photophysics of special pairs independently of the complexities of native photosynthetic proteins, and as a first step toward crea...

Charge redistribution of a spatially differentiated ferroelectric Bi4Ti3O12 single crystal for photocatalytic overall water splitting
2024 / Nature CommunicationsArtificial photosynthesis is a promising approach to produce clean fuels via renewable solar energy. However, it is practically constrained by two issues of slow photogenerated carrier migration and rapid electron/hole recombination. It is also a challenge to achieve a 2:1 ratio of H2 and O2 for overall water splitting. Here we report a rational design of spatial...

Preparation of thiourea derivative incorporated Ag3PO4 core shell for enhancement of photocatalytic degradation performance of organic dye under visible radiation light
2024 / Scientific ReportsPhotocatalysis is a promising technique to reduce hazardous organic pollutants using semiconductors under visible light. However, previous studies have been concerned with the behavior of silver phosphate (Ag3PO4) as n-type semiconductors, and the problem of their instability is still under investigation. Herein, 4,4′-(((oxalylbis(azanediyl)) bis(carbonothi...

Emergence of a short peptide based reductase via activation of the model hydride rich cofactor
2024 / Nature CommunicationsIn extant biology, large and complex enzymes employ low molecular weight cofactors such as dihydronicotinamides as efficient hydride transfer agents and electron carriers for the regulation of critical metabolic processes. In absence of complex contemporary enzymes, these molecular cofactors are generally inefficient to facilitate any reactions on their own. Here...

Pretreatment-free SERS sensing of microplastics using a self-attention-based neural network on hierarchically porous Ag foams
2024 / Nature CommunicationsLow-cost detection systems are needed for the identification of microplastics (MPs) in environmental samples. However, their rapid identification is hindered by the need for complex isolation and pre-treatment methods. This study describes a comprehensive sensing platform to identify MPs in environmental samples without requiring independent separation or pre-tre...

Broad-spectrum ubiquitin/ubiquitin-like deconjugation activity of the rhizobial effector NopD from Bradyrhizobium (sp. XS1150)
2024 / Communications BiologyThe post-translational modification of proteins by ubiquitin-like modifiers (UbLs), such as SUMO, ubiquitin, and Nedd8, regulates a vast array of cellular processes. Dedicated UbL deconjugating proteases families reverse these modifications. During bacterial infection, effector proteins, including deconjugating proteases, are released to disrupt host cell defense...

Enhancing Single-Layer WSe2 Light Emission in Perylene-Doped Polymer Films through Efficient Energy Transfer
2024 / Advanced Functional MaterialsThe optical and mechanical properties of 2D semiconductors make them excellent candidates for the active components of plastic optoelectronic devices. Here, the integration of single-layer WSe2 (1L-WSe2) into a polystyrene (PS) film containing dispersed perylene orange (PDI-O) molecules is investigated. The findings reveal a notable enhancement in the light emissio...

Molecular orbital breaking in photo-mediated organosilicon Schiff base ferroelectric crystals
2024 / Nature CommunicationsFerroelectric materials, whose electrical polarization can be switched under external stimuli, have been widely used in sensors, data storage, and energy conversion. Molecular orbital breaking can result in switchable structural and physical bistability in ferroelectric materials as traditional spatial symmetry breaking does. Differently, molecular orbital breaki...

Foldamers controlled by functional triamino acids: structural investigation of α/γ-hybrid oligopeptides
2024 / Communications ChemistryPeptide-like foldamers controlled by normal amide backbone hydrogen bonding have been extensively studied, and their folding patterns largely rely on configurational and conformational constraints induced by the steric properties of backbone substituents at appropriate positions. In contrast, opportunities to influence peptide secondary structure by functional gr...
