Biogenesis of mitochondrial porin [PDF]

open access: yes, 1990
We review here the present knowledge about the pathway of import and assembly of porin into mitochondria and compare it to those of other mitochondrial proteins.

Porins of Brucella species [PDF]

open access: yesInfection 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

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

open access: yesFrontiers 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.

Biosynthesis of Mitochondrial Porin and Insertion into the Outer Mitochondrial Membrane of Neuruspora crassa [PDF]

open access: yes, 1982
Mitochondrial porin, the major protein of the outer mitochondrial membrane is synthesized by free cytoplasmic polysomes. The apparent molecular weight of the porin synthesized in homologous or heterologous cell-free systems is the same as that of the ...

Porin Expression Profiles in Haemaphysalis longicornis Infected With Babesia microti

open access: yesFrontiers 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

open access: yesmSystems, 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.

open access: yesPLoS 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.

Phage resistance profiling identifies new genes required for biogenesis and modification of the corynebacterial cell envelope

open access: yeseLife, 2022
Bacteria of the order Corynebacteriales including pathogens such as Mycobacterium tuberculosis and Corynebacterium diphtheriae are characterized by their complex, multi-layered envelope.

The porin and the permeating antibiotic: A selective diffusion barrier in gram-negative bacteria [PDF]

open access: yes, 2008
Gram-negative bacteria are responsible for a large proportion of antibiotic resistant bacterial diseases. These bacteria have a complex cell envelope that comprises an outer membrane and an inner membrane that delimit the periplasm.

Mitochondrial protein import [PDF]

open access: yes, 1989
Proteolytic degradation of receptor sites on the mitochondrial surface strongly reduces the efficiency of mitochondrial protein import. The remaining residual import still involves basic mechanisms of protein import, including: insertion of precursors ...
