Carotenoids bind rhodopsins and act as photocycle-accelerating pigments in marine Bacteroidota

Nature Microbiology
Microbial rhodopsins are photoreceptor proteins widely distributed in marine microorganisms that harness light energy and support marine ecosystems. While retinal is typically the sole chromophore in microbial rhodopsins, some proteorhodopsins, which are proton-pumping rhodopsins abundant in the ocean, use carotenoid antennae to transfer light energy ...

TamL is a Key Player of the Outer Membrane Homeostasis in Bacteroidota

Journal of Molecular Biology
Abstract In Proteobacteria, the outer membrane protein TamA and the inner membrane-anchored protein TamB form the Translocation and Assembly Module (TAM) complex, which facilitates the transport of autotransporters, virulence factors, and likely lipids across the two membranes.

Novel laminarin-binding CBMs in multimodular proteins of marine Bacteroidota feature prominently in phytoplankton blooms

2023
Abstract The ß-(1,3)-glucan laminarin functions as storage polysaccharide in marine stramenophiles such as diatoms. Laminarin is abundant, water-soluble and structured simply, making it an attractive substrate for marine bacteria. As a consequence, many marine bacteria have developed competitive strategies to scavenge

Unraveling Fitness Landscapes in Plant-Associated Bacteroidota

Abstract Members of the bacterial phylum Bacteroidota inhabit a wide range of ecosystems. Although significant progress has been made over the past decade in understanding the metabolic functions of clinically relevant Bacteroidota , far less is known about the environmental species.

Community dynamics and metagenomic analyses reveal Bacteroidota's role in widespread enzymatic Fucus vesiculosus cell wall degradation

Scientific Reports
AbstractEnzymatic degradation of algae cell wall carbohydrates by microorganisms is under increasing investigation as marine organic matter gains more value as a sustainable resource. The fate of carbon in the marine ecosystem is in part driven by these degradation processes.

Unravelling sulfobacin biosynthesis in Bacteroidota

Sulfonolipide, insbesondere die Klasse der Sulfobacine, sind wichtige Membranbestandteile vieler Bacteroidota und spielen eine wichtige Rolle bei der Gleitmotilität sowie der interzellulären Kommunikation. Trotz ihrer Bedeutung sind die subzelluläre Anordnung involvierter Enzyme und die Regulation des Biosynthesewegs bisher kaum erforscht.

Investigation of gliding motility in Bacteroidota

Bacteria from the phylum Bacteroidota move by gliding across surfaces. Movement of extracellular adhesins attached to a helically-arranged periplasmic track causes propulsion of cells in a corkscrewing motion. The gliding track is propelled by a rotary motor that also powers the Type 9 Secretion System (T9SS) that exports the gliding adhesins to the ...

Hybrid xyloglucan utilisation loci are prevalent among plant-associated Bacteroidota

Abstract The plant hemicellulose xyloglucan (XyG) is secreted from the roots of numerous plant species, including cereals, and contributes towards soil aggregate formation in terrestrial systems. Whether XyG represents a key nutrient for plant-associated bacteria is unclear. The phylum Bacteroidota are abundant in the

A conserved adaptor orchestrates co-secretion of synergistic type VI effectors in gut Bacteroidota

Cell Host and Microbe
Interbacterial competition is crucial for shaping microbial communities and is often mediated by type VI secretion systems (T6SSs) that inject effectors into competing bacteria. T6SS effectors are released via structural proteins such as VgrG, but the secretion timing and coordination are unclear.

Bacteroidota-derived Glycine Lipids Regulate Skeletal Muscle Inflammation and Mitochondrial Quality Control

Physiology
Introduction: The Western diet (WD) is characterized by high levels of sugar and cholesterol, which contribute to the development of metabolic diseases in part by disrupting gut microbiome composition and altering production of microbial metabolites that influence host metabolism and inflammation.
