Dual Membrane-spanning Anti-Sigma Factors Regulate Vesiculation in Gut Bacteroidota
Biorxiv : the Preprint Server for Biology
|July 28, 2023
Summary
Researchers discovered a new family of Dual Membrane-spanning Anti-sigma factors (Dma) that regulate Outer Membrane Vesicle (OMV) biogenesis in Bacteroidota, crucial human gut bacteria.
Area of Science:
- Microbiology
- Molecular Biology
- Human Gut Microbiome Research
Background:
- Bacteroidota are key human gut bacteria influencing host immunity and nutrient metabolism.
- Outer Membrane Vesicles (OMVs) play a significant role in these interactions.
- Regulation of OMV biogenesis in Bacteroidota remains poorly understood.
Conclusions:
- The Dma family represents a unique regulatory mechanism for OMV biogenesis in Bacteroidota.
- This study provides the first mechanistic insights into OMV production regulation in human gut bacteria.
- Findings advance our understanding of Bacteroidota-host interactions and microbial community dynamics.

Overview of Secretory Vesicles
8.6K
Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...

Gene Regulation in Microbial Communities: Quorum Sensing
40
Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...

Global Regulatory Systems
44
Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...

Gene Regulation During Sporulation
36
Sporulation is a complex developmental process that allows certain Gram-positive bacteria, such as Bacillus subtilis and Clostridium species, to survive extreme environmental conditions. This process is tightly regulated by a series of signaling cascades and transcriptional controls, ensuring the formation of a highly resistant endospore.Sporulation is triggered by unfavorable conditions, such as nutrient depletion, and is governed by a phosphorelay system. One of the sensor kinases, such as...

Bacterial Signaling
32.8K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Gram-negative Bacterial Protein Secretion Systems
47
Gram-negative bacteria utilize sophisticated protein secretion systems to transport proteins across their double-membrane envelope into the extracellular environment or host cells. Based on their mechanism of action, these systems are classified into one-step and two-step pathways.One-Step Secretion Systems (Types I, III, IV, and VI)One-step secretion systems bypass the periplasm entirely, forming a continuous channel that spans both the inner and outer membranes:Type I Secretion System (T1SS):...
