This study identifies the non-coding RNA RsaE as a critical regulator in MRSA that, in conjunction with RNase Y, fine-tunes phenol-soluble modulin (PSM) expression through post-transcriptional and transcriptional mechanisms, thereby controlling biofilm architecture, cell viability, and systemic dissemination during infection.
This study establishes N6-methyldeoxyadenosine (N6medA) as a novel, age-associated DNA modification in the human brain that accumulates linearly with chronological age, shows elevated levels in Alzheimer's disease, and interacts with specific reader proteins to potentially drive neurodegenerative processes.
This study elucidates the structural mechanism by which IscB targets single-stranded nucleic acids, revealing a conformational checkpoint involving an HNH roadblock that regulates nuclease activation, and leverages these insights to engineer variants with significantly improved RNA-targeting efficiency.
This study identifies and characterizes Ag0826, a unique PCL-degrading enzyme from the marine bacterium *Alloalcanivorax gelatiniphagus* that exhibits weak PET-hydrolyzing activity and represents a distinct phylogenetic clade within the PET hydrolase family.
This computational study reveals that cancer-causing mutations in SHP-1 and SHP-2 disrupt the allosteric regulation of the catalytic WPD-loop dynamics by the SH2 domains, thereby altering enzyme activity and offering new insights for selective drug targeting.
This study elucidates the crystal structure of the Drosophila adaptor protein Egalitarian bound to the K10 mRNA localization signal, revealing a modular binding mechanism that is essential for asymmetric mRNA transport and validated by functional deficits in genome-edited flies with mutations in the identified RNA-recognition residues.
Using a transient protein-RNA crosslink and Cryo-EM, researchers determined the 3.0 Å structure of the antibiotic resistance enzyme Cfr bound to an L-shaped rRNA fragment, revealing the structural basis for its unique C8 methylation activity.
EnzySeek is an AI agent that leverages Large Language Models, a curated enzyme catalysis knowledge base, and Model Context Protocol interfaces to autonomously execute and validate complex enzyme simulation workflows—from protein structure prediction to QM/MM calculations—while continuously learning from human-verified results to advance the automation of enzyme catalysis research.
This study demonstrates that the bacterial ESCRT-III protein IM30 forms stress-responsive biomolecular condensates via liquid-liquid phase separation, a process driven by its structured 1-3 helical hairpin domain and triggered by environmental stress-induced acidification that lowers the phase-separation barrier.
This study elucidates the structural mechanism by which a nuclease-dead Cas12f protein, guided by RNA and complexed with a unique sigma factor, activates bacterial transcription by recruiting RNA polymerase to a specific downstream site while bypassing classical promoter recognition through novel stabilization of the melted DNA.
