Signal Recognition Particle RNA Contributes to Oxidative Stress Response in Deinococcus radiodurans by Modulating Catalase Localization

Frontiers in Microbiology, 2020
The proper functioning of many proteins requires their transport to the correct cellular compartment or their secretion. Signal recognition particle (SRP) is a major protein transport pathway responsible for the co-translational movement of integral ...

Periplasmic glucans isolated from Proteobacteria

BMB Reports, 2009
Periplasmic glucans (PGs) are general constituents in the periplasmic space of Proteobacteria. PGs from bacterial strains are found in larger amounts during growth on medium with low osmolarity and thus are often been specified as osmoregulated periplasmic glucans (OPGs). Furthermore, they appear to play crucial roles in pathogenesis and symbiosis. PGs

The ABCDs of Periplasmic Copper Trafficking [PDF]

Structure, 2002
The structure of the CopC protein of Pseudomonas syringae pathovar tomato provides fascinating clues, not only to its role in the periplasmic space in copper resistance, but also to features important for copper trafficking and homeostasis that may be conserved in a variety of biological systems.

Bioengineered Bacterial Vesicles and Biomimetic Hybrids Eliminate Biofilms and Balance the Gut Microbiome

Small, EarlyView.
Biomimetic nanocarriers based on liposomes and Myxobacteria outer‐membrane vesicles (OMVs) are effective antibiotic delivery systems. Hybrids have a higher drug loading and can target intracellular pathogens, while OMVs evade immune clearance. Biomimetic nanoantibiotics effectively eliminate the biofilms of Gram‐negative bacteria. Besides, Myxobacteria

Kinetic Properties of α
-Galactosidase and the Localization of Total Proteins in Erwinia chrysanthemi

Food Technology and Biotechnology, 2004
Erwinia chrysanthemi is an enterobacterium that causes soft-rot in plants in general, resulting in enormous economic losses annually. For the pathogen to survive in the host plant, it has to use the readily assimilable compounds from the host fluids and ...

SecY-mediated quality control prevents the translocation of non-gated porins

Scientific Reports, 2020
OmpC and OmpF are among the most abundant outer membrane proteins in E. coli and serve as hydrophilic channels to mediate uptake of small molecules including antibiotics.

Periplasmic biomineralization for semi-artificial photosynthesis

Science Advances, 2023
Semiconductor-based biointerfaces are typically established either on the surface of the plasma membrane or within the cytoplasm. In Gram-negative bacteria, the periplasmic space, characterized by its confinement and the presence of numerous enzymes and peptidoglycans, offers additional opportunities for biomineralization, allowing for nongenetic ...

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Periplasmic Superoxide Dismutase in Meningococcal Pathogenicity [PDF]

Infection and Immunity, 1998
ABSTRACT Meningococcal sodC encodes periplasmic copper- and zinc-cofactored superoxide dismutase (Cu,Zn SOD) which catalyzes the conversion of the superoxide radical anion to hydrogen peroxide, preventing a sequence of reactions leading to production of toxic hydroxyl free radicals.

Late Stage Mannan Metabolism in Cellvibrio japonicus Requires the Combined Action of a Mannosyl‐Glucose Phosphorylase and a Mannobiose Epimerase

Molecular Microbiology, EarlyView.
Model for the non‐PTS utilization of manno‐oligosaccharides by Cellvibrio japonicus. The Mgp130A and EpiA enzymes are essential for the utilization of mannose residues. ABSTRACT Manno‐oligosaccharides and their metabolism play important roles in gut health, pharmaceutical development, and renewable chemical production.
