Polymyxins slow down lateral diffusion of proteins and lipopolysaccharide in the E. coli outer membrane

open access: yesCommunications Biology
Polymyxins are often administered as last resort antibiotics for Gram-negative bacterial infections. However, given unwanted side-effects, efficacy and recent reports of resistance against polymyxins, there is an urgency to develop alternatives.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

open access: yesMolecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Domain organization of long autotransporter signal sequences [PDF]

open access: yes, 2010
Bacterial autotransporters represent a diverse family of proteins that autonomously translocate across the inner membrane of Gram-negative bacteria via the Sec complex and across the outer bacterial membrane.

Chlamydial infection from outside to inside [PDF]

open access: yes, 2019
Chlamydia are obligate intracellular bacteria, characterized by a unique biphasic developmental cycle. Specific interactions with the host cell are crucial for the bacteria's survival and amplification because of the reduced chlamydial genome.

Analyzing the molecular mechanism of lipoprotein localization in Brucella

open access: yesFrontiers in Microbiology, 2015
Bacterial lipoproteins possess comprehensive structure and functionality, ranging from bacterial physiology to pathogenic processes. As such many lipoproteins, originating from Brucella are exploited as potential vaccines to countermeasure brucellosis ...

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Biogenesis of mitochondrial c-type cytochromes [PDF]

open access: yes, 1990
Cytochromesc andc 1 are essential components of the mitochondrial respiratory chain. In both cytochromes the heme group is covalently linked to the polypeptide chain via thioether bridges. The location of the two cytochromes is in the intermembrane space;

Membrane Protein Simulations: Ion Channels And Bacterial Outer Membrane Proteins

open access: yes, 2003
Publisher Summary The chapter focuses on two classes that have been investigated by a number of research groups—namely, ion channels and bacterial outer membrane proteins—rather than attempt to cover all simulations of membrane proteins. Ion channels play a key role in the electrical activity of cells of the nervous system. However, channels are also

Chaperone Spy Protects Outer Membrane Proteins from Folding Stress via Dynamic Complex Formation

open access: yesmBio, 2021
Outer membrane proteins (OMPs) play critical roles in bacterial pathogenicity and provide a new niche for antibiotic development. A comprehensive understanding of the OMP quality control network will strongly impact antimicrobial discovery.
