ProteomicsIdentification of a novel xanthan-binding module of a multi-modular Cohnella sp. xanthanase
A new strain of xanthan-degrading bacteria identified as Cohnella sp. has been isolated from a xanthan thickener for food production. The strain was able to utilize xanthan as the only carbon source and reduce the viscosity of the xanthan-containing medium during cultivation. Xanthan hydrolytic acti...

ProteomicsA twin xanthan lyase-dependent xanthan degradation system in Paenibacillus taichungensis I5
Xanthan gum, a natural heteropolysaccharide produced by Xanthomonas species, has many biotechnological applications across industries due to its unique rheological properties. Expanding its utility requires specific enzymes capable of targeted xanthan modification or degradation. In this study, a no...

ProteomicsOptogenetic rejuvenation of mitochondrial membrane potential extends C. elegans lifespan
Despite longstanding scientific interest in the centrality of mitochondria to biological aging, directly controlling mitochondrial function to test causality has eluded researchers. We show that specifically boosting mitochondrial membrane potential through a light-activated proton pump reversed age...

ProteomicsExtracellular Vesicles From Xylella fastidiosa Carry sRNAs and Genomic Islands, Suggesting Roles in Recipient Cells
Xylella fastidiosa (Xf) is a Gram-negative bacterial plant pathogen responsible for severe diseases in a variety of economically important crops. A critical aspect of its virulence is the production of extracellular vesicles (EVs). In this study, we discovered that DNA-binding proteins and non-ribos...

ProteomicsComparative proteomics of meat-spoiling bacteria predicts drivers for their coexistence on modified atmosphere packaged meat
Oxygen and carbon dioxide are common protective gases used in modified atmosphere packaging (MAP) of meat. Within the package, they selectively suppress members of the spoilage microbiome, reshaping it to adapted species concomitantly growing upon MAP. Thus, this species must exhibit adaptation mech...

ProteomicsFaecal Proteases and Immune Signatures Drive Subtype-Specific Enteric Neuronal Activation in IBS
Background: Luminal proteases have been implicated in epithelial barrier dysfunction and visceral hypersensitivity in irritable bowel syndrome (IBS), yet their impact on the enteric nervous system (ENS), the principal regulator of gastrointestinal function, remains unknown. We investigated whether ...

ProteomicsCharacterizing Peptidase Activity of Barley Endoprotease B in Complex Technical Matrices of the Beer Brewing Process
Barley cysteine endoprotease B (HvEPB) is an important enzyme in plant biology and food production. Pilot-scale fed-batch fermentation with Komagataella phaffii in minimal FM22 medium enabled controlled recombinant HvEPB (r-HvEPB) secretion. Peptidomics across four technological brewing matrices - r...
