Control of membrane lipid fluidity by molecular thermosensors.

Lipid fluidity and membrane protein dynamics.

Membrane fluidity plays an important role in cellular functions. Membrane proteins are mobile in the lipid fluid environment; lateral diffusion of membrane proteins is slower than expected by theory, due to both the effect of protein crowding in the membrane and to constraints from the aqueous matrix. A major aspect of diffusion is in macromolecular associations: reduction of dimensionality for...

Lipid molecular species retailoring and membrane fluidity.

on cell morphology, i.e. the formation of stomatocytes, when the native mixed-acid PC species in the monolayer are replaced by (1,2-dilinoleoyl)-PC (Fig. 1). This species has a pronounced cone shape because of a larger cross-section at the end of its hydrophobic tails. Consequently, the outer monolayer, and thereby the whole membrane, will bend inwards. Further support for the above hypothesis ...

Lipid Composition and Membrane Fluidity of Butanol-Tolerant

The effect of butanol challenge (0, 1.0, 1.5% [vol/vol]) and growth temperature (22, 37, 42°C) on the membrane composition and fluidity of Clostridium acetobutylicum ATCC 824 and a butanol-tolerant mutant, SA-2, was examined in chemically defined medium. Growth of strain ATCC 824 into the stationary phase coincided with a gradual increase in the percent saturated to percent unsaturated (SU) fat...

The lipid fluidity of rat liver membrane subfractions.

1. The lipid fluidity of three major rat liver plasma-membrane subfractions, as well as Golgi apparatus and endocytic fractions, was assessed with a fatty acid spin probe by using e.s.r. techniques. 2. The sinusoidal (blood-facing) plasma-membrane subfraction was the most fluid of the three plasma-membrane regions. Fractions originating from the bile-canalicular and contiguous (lateral) regions...
