Molecular Structural Control of the Amorphous-Crystalline Balance in Solids: Structure-Phase Correlation in DADQs with Enhanced/Switchable Fluorescence.

The amorphous/crystalline (A/C) assembly in molecular solids has a direct bearing on their attributes and applications, including mechanical, pharmaceutical, electronic and photophysical.  A systematic analysis of the molecular features and interactions that determine the predilection towards the A, C or bi-stable A-C states is critical.  This fundamental problem is addressed through an exhaustive investigation of a large family of alkoxyalkyl diaminodicyanoquinodimethanes (ROR'-DADQs); enhancement of their fluorescence from the solution, to the A, to the C state serves as an excellent signature of the phase preference and temporal stability.

Copper catalyzed selective methane oxidation to acetic acid using O.

The direct transformation of methane into C oxygenates such as acetic acid selectively using molecular oxygen (O) is a significant challenge due to the chemical inertness of methane, the difficulty of methane C-H bond activation/C-C bond coupling and the thermodynamically favored over-oxidation. In this study, we have successfully developed a porous aluminium metal-organic framework (MOF)-supported single-site mono-copper(ii) hydroxyl catalyst [MIL-53(Al)-Cu(OH)], which is efficient in directly oxidizing methane to acetic acid in water at 175 °C with a remarkable selectivity using only O. This heterogeneous catalyst achieved an exceptional acetic acid productivity of 11 796 mmol mol h in 9.

Structural Evidence for DUF512 as a Radical -Adenosylmethionine Cobalamin-Binding Domain.

Cobalamin (Cbl)-dependent radical -adenosylmethionine (SAM) enzymes constitute a large subclass of radical SAM (RS) enzymes that use Cbl to catalyze various types of reactions, the most common of which are methylations. Most Cbl-dependent RS enzymes contain an N-terminal Rossmann fold that aids Cbl binding. Recently, it has been demonstrated that the methanogenesis marker protein 10 (Mmp10) requires Cbl to methylate an arginine residue in the α-subunit of methyl coenzyme M reductase.

Protacs in cancer therapy: mechanisms, design, clinical trials, and future directions.

Cancer develops as a result of changes in both genetic and epigenetic mechanisms, which lead to the activation of oncogenes and the suppression of tumor suppressor genes. Despite advancements in cancer treatments, the primary approach still involves a combination of chemotherapy, radiotherapy, and surgery, typically providing a median survival of approximately five years for patients. Unfortunately, these therapeutic interventions often bring about substantial side effects and toxicities, significantly impacting the overall quality of life for individuals undergoing treatment.

Bacterial Rps3 counters oxidative and UV stress by recognizing and processing AP-sites on mRNA via a novel mechanism.

Lesions and stable secondary structures in mRNA severely impact the translation efficiency, causing ribosome stalling and collisions. Prokaryotic ribosomal proteins Rps3, Rps4 and Rps5, located in the mRNA entry tunnel, form the mRNA helicase center and unwind stable mRNA secondary structures during translation. However, the mechanism underlying the detection of lesions on translating mRNA is unclear.
