Pyrene excimer fluorescence: a spatially sensitive probe to monitor lipid-induced helical rearrangement of apolipophorin III.

Biochemistry - 6 Jun 2000

Sahoo D, Narayanaswami V, Kay C M, Ryan R O

Abstract excerpt

Manduca sexta apolipophorin III (apoLp-III), an 18-kDa, monomeric, insect hemolymph apolipoprotein, is comprised of five amphipathic alpha-helices arranged as a globular bundle in the lipid-free state. Upon lipid binding, it is postulated that the bundle opens, exposing a continuous hydrophobic surface which becomes available for lipid interaction. To investigate lipid binding-induced helical rearrangements, we...
