Methane hydroxylation presents a promising approach to produce high-energy methanol from potent greenhouse gases, thereby contributing to a more sustainable future. Despite its environmental importance, current research on this process remains challenging due to the harsh operating conditions for the activation of inert C-H bond in methane. In nature, methane mon...
Continue readingThe biosynthesis of ribosomally synthesized and post-translationally modified peptides (RiPPs) involves binding of the N-terminal leader region of precursor peptides to peptide-modifying enzymes and subsequent modification of the C-terminal core. Canonical RiPP leaders are short and unstructured. However, atypical RiPP leaders called nitrile hydratase-like leader...
Continue readingThe existence of linear cholesterol-recognition motifs in transmembrane domains has long been debated. Evolutionary molecular dynamics (Evo-MD) simulations—genetic algorithms guided by (coarse-grained) molecular force-fields–reveal that thermodynamic optimal cholesterol attraction in isolated alpha-helical transmembrane domains occurs when multiple co...
Continue readingThe enzymatic depolymerization of single-use plastic products, primarily made from poly(ethylene terephthalate) (PET), is now a reality. Herein, we report the development of an innovative tandem system process that uses engineered enzymes and Escherichia coli strains to depolymerize PET and convert the resulting products into enantiomers of alanine, useful amino ac...
Continue readingGene-silencing mechanisms using RNA interference (RNAi) and antisense oligomers have drawn attention to nucleic acid medicines. However, several challenges remain such as low in vivo stability and inadequate target selectivity. Here we report a versatile and highly selective method for suppressing gene expression with a short oligonucleotide. The oligonucleotide,...
Continue readingDengue and leptospirosis are prevalent diseases in tropical and subtropical regions, posing significant public health challenges. These illnesses exhibit overlapping symptoms, including fever, muscle pain, and headaches, which complicates diagnosis and delays appropriate treatment. This study explores the use of attenuated total reflectance-Fourier transform infr...
Continue readingThe accumulation of intracellular aggregates of Tau protein is one main hallmark of Alzheimer’s disease (AD) and is the consequence of Tau conformational changes, increased phosphorylation, and self-association to form fibrillar aggregates. This pathological process prevents the physiological interaction of Tau with microtubules to the detriment of the stru...
Continue readingChaperone proteins are essential for maintaining proteostasis. Their main role is to assist with the folding of other proteins and to prevent the aggregation of misfolded proteins. The molecular chaperone DNAJB6b efficiently suppresses amyloid formation of several peptides. This activity may rely on the same physicochemical properties as those driving chaperone sel...
Continue readingWhereas sanitizing wipes are among the strategies for combatting COVID-19, there are growing concerns concerning their disposal, due to majority of them being made of non-biodegradable fibres. Additionally, majority of the sanitizing solutions used are associated with irritations and some are carcinogenic. In this study, banana wipes, impregnated with an organic ...
Continue readingMarine-derived microorganisms are renowned for producing structurally diverse secondary metabolites with notable biological activities, serving as a promising reservoir for pharmaceutical development. In this study, the fungal strain Westerdykella dispersa Ca4-13, isolated from the edible oyster Crassostrea angulata, was investigated for its potential anti-inflamma...
Continue readingFructooligosaccharides (FOS) have gained attention due to their prebiotic properties and potential health benefits. This study explores the production of FOS using Zymomonas mobilis ZM4, a promising candidate for biotechnological processes, utilizing corn steep liquor (CSL) and sugarcane molasses as alternative and sustainable carbon and nitrogen sources. Two disti...
Continue readingTriplet-triplet annihilation photon upconversion seeks efficient conversion of low-energy photons to high-energy emission. However, the triplet-triplet annihilation photon upconversion system faces limitations in emission gamut because efficient triplet-triplet energy transfer between sensitizer and annihilator relies on triplet energy matching, making it challen...
Continue readingAquatic bacterial rhodopsin proton pumps harvest light energy for photoheterotrophic growth and are known to contain hydroxylated carotenoids that expand the wavelengths of light utilized, but these have not been characterized in marine archaea. Here, by combining a marine chromophore extract with purified archaeal rhodopsins identified in marine metagenomes, we ...
Continue readingWe first demonstrate a nonaqueous rechargeable battery using uranium and iron as active materials. This uranium-iron battery achieves an open-circuit voltage of approximately 1.3 V, exhibits stable cycling performance, and delivers a good Coulombic efficiency of 86 ± 2%. These characteristics suggest a promising avenue for utilizing depleted ur...
Continue readingIn this work, the synthesis of smart hosting materials from modified gelatin with different fatty acids (myristic acid, palmitic acid, and stearic acid) has been observed and characterized. Coconut oil was used as a natural phase change material (PCM) and octadecanol was used as an organic phase change material. Different concentrations of Phase change materials we...
