Energetics and Mechanism of Drug Transport Mediated by the Lactococcal Multidrug Transporter LmrP [PDF]

, 1996
The gene encoding the secondary multidrug transporter LmrP of Lactococcus lactis was heterologously expressed in Escherichia coli. The energetics and mechanism of drug extrusion mediated by LmrP were studied in membrane vesicles of E. coli. LmrP-mediated

Fluid Vesicles with Viscous Membranes in Shear Flow [PDF]

, 2004
The effect of membrane viscosity on the dynamics of vesicles in shear flow is studied. We present a new simulation technique, which combines three-dimensional multi-particle collision dynamics for the solvent with a dynamically-triangulated membrane ...

Formation of intracellular vesicles within the Gram+ Lactococcus lactis induced by the overexpression of Caveolin-1β

Microbial Cell Factories, 2022
Background Caveolae are invaginated plasma membrane domains of 50–100 nm in diameter involved in many important physiological functions in eukaryotic cells.

Membrane vesicle-mediated bacterial communication [PDF]

The ISME Journal, 2017
Abstract The classical quorum-sensing (QS) model is based on the assumption that diffusible signaling molecules accumulate in the culture medium until they reach a critical concentration upon which expression of target genes is triggered.

A role for the membrane in regulating Chlamydomonas flagellar length. [PDF]

PLoS ONE, 2013
Flagellar assembly requires coordination between the assembly of axonemal proteins and the assembly of the flagellar membrane and membrane proteins. Fully grown steady-state Chlamydomonas flagella release flagellar vesicles from their tips and failure to

Biogenesis of bacterial membrane vesicles [PDF]

Molecular Microbiology, 2009
SummaryMembrane vesicle (MV) release remains undefined, despite its conservation among replicating Gram‐negative bacteria both in vitro and in vivo. Proteins identified in Salmonella MVs, derived from the envelope, control MV production via specific defined domains that promote outer membrane protein–peptidoglycan (OM–PG) and OM protein–inner membrane ...

Biophysical Characterization of Membrane Phase Transition Profiles for the Discrimination of Outer Membrane Vesicles (OMVs) From Escherichia coli Grown at Different Temperatures

Frontiers in Microbiology, 2020
Dynamic Light Scattering (DLS), Small Angle X-ray Scattering (SAXS) and Transmission Electron Microscopy (TEM) are physical techniques widely employed to characterize the morphology and the structure of vesicles such as liposomes or human extracellular ...

Fusion of secretory vesicles isolated from rat liver [PDF]

, 1978
Secretory vesicles isolated from rat liver were found to fuse after exposure to Ca2+. Vescle fusion is characterized by the occurrence of twinned vesicles with a continuous cleavage plane between two vesicles in freeze-fracture electron microscopy.
