T7 RNA polymerase (T7 RNAP) is a foundational enzyme for biotechnology, but its utility for many potential applications is limited by low thermal stability of 43-44°C. While stabilized variants exist, the most stable commercial version has a proprietary sequence. In this work we developed a highly stable T7 RNAP using…

Vapor-deposited organic glasses can show enhanced kinetic stability relative to liquid-cooled glasses. When such stable glasses of model glassformers are annealed above the glass transition temperature Tg, they lose their thermal stability and transform into the supercooled liquid via constant velocity propagating…

This study utilized capric acid (CA), lauric acid (LA), myristic acid (MA), palmitic acid (PA), and stearic acid (SA) as alternative feedstocks to conduct theoretical analyses on ten fatty acid-based ternary eutectic systems. By leveraging the Schrader equation, phase diagrams for each system were constructed, and…

The unfolding or melting temperature (T_M_) is a central quantity to characterize the stability of proteins and other biopolymers. The accurate prediction of protein melting temperatures by molecular mechanics force field simulations is highly desirable for many biophysical and biotechnological applications. Since the…

Enzymes used on industrial scale are routinely engineered for best performance. However, exhaustive mutagenesis campaigns using the twenty canonical proteinogenic amino acids rapidly reach an evolutionary ceiling, where gains in activity compromise other critical properties such as thermal endurance. Although…

Apolipoprotein E (ApoE) is the primary genetic risk modifier of late-onset Alzheimer’s disease, with the ε4 allele increasing risk up to 15-fold relative to ε3. The structural differences between isoforms are thought to underlie their distinct effects on lipid transport, receptor binding, and disease risk. ApoE4…

Storage of biological materials is essential for medical, research, and biotechnological applications. While cold-chain preservation is effective, it is costly, infrastructure-dependent, and vulnerable to disruption. Room-temperature dry storage, inspired by desiccation-tolerant organisms, provides an alternative by…
