Heterogeneous Lipid Distributions in Membranes as Revealed by Electronic Energy Transfer
Result description
The techniques achieving the highest resolution only can characterize/nmembrane heterogeneities on the lowest molecular level. When F€orster resonance/nenergy transfer (FRET) is combined with Monte-Carlo (MC) simulations and is/napplied to the measurement of nanodomain/pore sizes it reaches an unbeatable/nresolution of 2–50 nm. While other techniques start being less efficient at such/nshort distances FRET is most efficient in this region. Here, usefulness of/nMC-FRET is demonstrated on three different systems that contain heterogeneously/ndistributed lipids: a nanoscopically phase separated bilayer, a bilayer containing/npores and finally on bicelles consisting of highly curved and flat regions. Moreover,/nthis paper gives the reader information on how a FRET experiment should be/ndesigned to achieve the highest FRET resolution but also which experimental/nconditions should be avoided. The theory describing FRET between randomly/ndistributed donors and acceptors in a lipid bilayer is also described in this paper as/nwell as reasons are explained why for heterogeneous probe distribution MC simulations/nshould rather be used.
