Emergence of Tigecycline-Resistant Pseudomonas aeruginosa Harbouring tmexC6D6-toprJ1b From Hospital Sewage in Japan. [PDF]

Environ Microbiol Rep
This study isolated a Pseudomonas aeruginosa strain (KAM950) carrying the tmexCD‐toprJ gene cluster from hospital sewage in Japan. The strain exhibited reduced susceptibility to tigecycline and carbapenems, harboured chromosomal tmexC6D6‐toprJ1b and oprD disruption, and belonged to epidemic clone ST244, emphasising emerging multidrug resistance and the

Voltage-Dependent Anion Selective Channel Isoforms in Yeast: Expression, Structure, and Functions

Frontiers in Physiology, 2021
Mitochondrial porins, also known as voltage-dependent anion selective channels (VDACs), are pore-forming molecules of the outer mitochondrial membranes, involved in the regulation of metabolic flux between cytosol and mitochondria.

Porins of Brucella species [PDF]

Infection and Immunity, 1984
The outer membrane of Brucella species contains two major proteins, denoted as group 2 and group 3 proteins (Verstreate et al., Infect. Immun. 35:979-989, 1982). We reconstituted proteoliposomes from the purified proteins and egg phosphatidylcholine and showed that group 2 proteins, but not a group 3 protein, had the porin activity. The influx rates of

Porin fromThiobacillus versutus [PDF]

FEMS Microbiology Letters, 1989
The porin of Thiobacillus versutus IFO 14567 was isolated by extraction of cell-envelopes with sodium dodecyl sulfate. It exhibited strong porin-activity after reconstitution into artificial lipid bilayer membranes. The diameter of the pore was determined as 1.6 nm, with a weak selectivity for cations being observed. The porin migrated as a single band

Porin Expression Profiles in Haemaphysalis longicornis Infected With Babesia microti

Frontiers in Physiology, 2020
The porin gene is widely disseminated in various organisms and has a pivotal role in the regulation of pathogen infection in blood-sucking arthropods. However, to date, information on the porin gene from the Haemaphysalis longicornis tick, an important ...

New Provisional Function of OmpA from Acinetobacter sp. Strain SA01 Based on Environmental Challenges

mSystems, 2021
An outer membrane protein A (OmpA) from Acinetobacter sp. strain SA01 was identified and characterized in-depth based on the structural and functional characteristics already known of its homologues.

Drosophila Porin/VDAC affects mitochondrial morphology.

PLoS ONE, 2010
Voltage-dependent anion channel (VDAC) has been suggested to be a mediator of mitochondrial-dependent cell death induced by Ca(2+) overload, oxidative stress and Bax-Bid activation.

Extracellular Vesicle-Mediated Secretion of Protochlorophyllide in the Cyanobacterium Leptolyngbya boryana

Plants, 2022
Protochlorophyllide (Pchlide) reduction in the late stage of chlorophyll a (Chl) biosynthesis is catalyzed by two enzymes: light-dependent Pchlide oxidoreductase (LPOR) and dark-operative Pchlide oxidoreductase (DPOR).
