A firehose for phospholipids

open access: yesJournal of Cell Biology, 2020
All lipid transport proteins in eukaryotes are thought to shuttle lipids between cellular membranes. In this issue, Li et al. (2020. J. Cell Biol.https://doi.org/10.1083/jcb.202001161) show that Vps13 has a channel-like domain that may allow lipids to flow between closely apposed membranes at contact sites.

Phospholipids of the Thiobacilli [PDF]

open access: yesJournal of Bacteriology, 1968
Phosphatidyl glycerol, disphosphatidyl glycerol, and phosphatidyl ethanolamine were found in all of the Thiobacillus species studied. T. thioparus possessed only these phospholipids. T. intermedius, T. neapolitanus , and T. thiooxidans contained

Phospholipid synthesis inside phospholipid membrane vesicles

open access: yesCommunications Biology, 2022
AbstractConstruction of living artificial cells from genes and molecules can expand our understanding of life system and establish a new aspect of bioengineering. However, growth and division of cell membrane that are basis of cell proliferation are still difficult to reconstruct because a high-yielding phospholipid synthesis system has not been ...

The phospholipids of corynebacteria [PDF]

open access: yesLipids, 1971
AbstractThe phospholipids ofCorynebacterium diphtheriae, Corynebacterium xerosis, Corynebacterium equi andCorynebacterium ovis were examined, largely by chromatographic procedures. In all of these, lipids of the phosphoinositide and mannophosphoinositide type were prominent.

Phospholipid signaling

open access: yesCell, 1995
Ten years ago, describing what is new in phospholipid signaling in ten pages of Cell would have been easy; it would have been essentially a summary of the phospho-inositidase C (PIC) story: phosphatidylinositol(4,5)bisphos-phate (Ptdlns(4,5)P2) hydrolysis to inositiol(1,4,5)trisphos-phate (Ins(1",4,5)P3), with the synergistic action of Ca 2÷(mobilized ...

The inositol phospholipids [PDF]

open access: yesJournal of Lipid Research, 1960
T h e dried crystals melted with decomposition a t about 215”. The substance is probably an organic acid but we have not yet had time to examine it thoroughly.” (1) In this modest way inositol seems to have made its first appearance as a lipid constituent.

Opsin Is a Phospholipid Flippase [PDF]

open access: yesCurrent Biology, 2011
Polar lipids must flip-flop rapidly across biological membranes to sustain cellular life [1, 2], but flipping is energetically costly [3] and its intrinsic rate is low. To overcome this problem, cells have membrane proteins that function as lipid transporters (flippases) to accelerate flipping to a physiologically relevant rate.

Ice Formation in Model Biological Membranes in the Presence of Cryoprotectors [PDF]

open access: yesNuclear Instruments & Methods in Physics Research A 448 (2000) 225-260, 2001
Ice formation in model biological membranes is studied by SAXS and WAXS in the presence of cryoprotectors: dimethyl sulfoxide and glycerol. Three types of phospholipid membranes: DPPC, DMPC, DSPC are chosen for the investigation as well-studied model biological membranes. A special cryostat is used for sample cooling from 14.1C to -55.4C.

Influence of Phospholipid and Protein Constituents on Tribological Properties of Artificial Hydrogel Cartilage Material

open access: yesJournal of Biomechanical Science and Engineering, 2013
In this study, the influence of phospholipid and protein constituents on friction and wear behavior of artificial hydrogel cartilage was investigated. A sliding pair of an ellipsoidal specimen of poly (vinyl alcohol) (PVA) hydrogel and a flat specimen of

Permeation characteristics of tetracyclines in parallel artificial membrane permeation assay II: Effect of divalent metal ions and mucin

open access: yesADMET and DMPK, 2020
The bioavailability of tetracyclines is markedly decreased when co-administered with antacids, milk, or food containing Ca2+. Previously, it was suggested that the effective intestinal permeation of tetracycline (TC) was decreased due to Ca2+ linked ...
