μ-calpain binds to lipid bilayers via the exposed hydrophobic surface of its Ca2+-activated conformation [PDF]

open access: yes, 2006
μ- and m-calpain are cysteine proteases requiring micro- and millimolar Ca2+ concentrations for their activation in vitro. Among other mechanisms, interaction of calpains with membrane phospholipids has been proposed to facilitate their activation by ...

Intricate Crosstalk Between Lipopolysaccharide, Phospholipid and Fatty Acid Metabolism in Escherichia coli Modulates Proteolysis of LpxC

open access: yesFrontiers in Microbiology, 2019
Lipopolysaccharides (LPS) in the outer membrane of Gram-negative bacteria provide the first line of defense against antibiotics and other harmful compounds. LPS biosynthesis critically depends on LpxC catalyzing the first committed enzyme in this process.

Effects of Gabaergic phenols on phospholipid bilayers as evaluated by 1H-NMR [PDF]

open access: yes, 2013
The phenols propofol and thymol, and lately carvacrol, eugenol and chlorothymol, have been shown to act as positive allosteric modulators on GABAA receptor, which is the main inhibitory receptor of the central nervous system.

Comparison of the Influence of Phospholipid-Coated Porous Ti-6Al-4V Material on the Osteosarcoma Cell Line Saos-2 and Primary Human Bone Derived Cells

open access: yesMetals, 2016
Biomaterial surface functionalization remains of great interest in the promotion of cell osteogenic induction. Previous studies highlighted the positive effects of porous Ti-6Al-4V and phospholipid coating on osteoblast differentiation and bone ...

Substrate-Specific Inhibition Constants for Phospholipase A2 Acting on Unique Phospholipid Substrates in Mixed Micelles and Membranes Using Lipidomics. [PDF]

open access: yes, 2019
Assaying lipolytic enzymes is extremely challenging because they act on water-insoluble lipid substrates, which are normally components of micelles, vesicles, and cellular membranes.

TECHNICAL AND CHEMICAL CHARACTERISTICS OF A DEEP-WATER SPECIES ANTIMORA MICROLEPIS

open access: yesИзвестия ТИНРО, 2019
Antimora microlepis is considered as a new object of deep-water fishery. Its body length in the catches of 2018 was 40–80 cm, on average 56 cm, weight — 570–5670 g, on average 2170 g.

The prolate-to-oblate shape transition of phospholipid vesicles in response to frequency variation of an AC electric field can be explained by the dielectric anisotropy of a phospholipid bilayer [PDF]

open access: yes, 2007
The external electric field deforms flaccid phospholipid vesicles into spheroidal bodies, with the rotational axis aligned with its direction. Deformation is frequency dependent: in the low frequency range (~ 1 kHz), the deformation is typically prolate,

Biomimetic lipid–fluorescein probe for cellular bioimaging

open access: yesFrontiers in Chemistry, 2023
Fluorescence probe is one of the most powerful tools for cellular imaging. Here, three phospholipid-mimicking fluorescent probes (FP1–FP3) comprising fluorescein and two lipophilic groups of saturated and/or unsaturated C18 fatty acids were synthesized ...

A basic model for the association of ligands with membrane cholesterol: application to cytolysin binding

open access: yesJournal of Lipid Research, 2023
Almost all the cholesterol in cellular membranes is associated with phospholipids in simple stoichiometric complexes. This limits the binding of sterol ligands such as filipin and perfringolysin O (PFO) to a small fraction of the total. We offer a simple

Liposomal-polyene preliposomal powder and method for its preparation [PDF]

open access: yes, 1993
A method is disclosed for preparing a stable preliposomal powder which, when reconstituted with water or saline solution, forms a suspension of liposomes containing a polyene drug, such as nystatin. The method involves the steps of combining at least one
