NMR Solution Structure and Dynamics of an Exchangeable Apolipoprotein, Locusta migratoria Apolipophorin III

Protein-lipid interactions of apolipophorin-III, a model exchangeable amphipathic apolipoprotein.

Structural basis for the conformational adaptability of apolipophorin III, a helix-bundle exchangeable apolipoprotein.

The high-resolution NMR structure of apolipophorin III from the sphinx moth, Manduca sexta, has been determined in the lipid-free state. We show that lipid-free apolipophorin III adopts a unique helix-bundle topology that has several characteristic structural features. These include a marginally stable, up-and-down helix bundle that allows for concerted opening of the bundle about "hinged" loop...

Primary structure and comparative sequence analysis of an insect apolipoprotein. Apolipophorin-III from Manduca sexta.

The amino acid sequence of an insect apolipoprotein, apolipophorin-III from Manduca sexta, was determined by a combination of cDNA and protein sequencing. The mature hemolymph protein consists of 166 amino acids. The cDNA also encodes for an amino-terminal extension of 23 amino acids which is not represented in the mature hemolymph protein. The existence of a precursor protein was confirmed by ...

Exchangeable apolipoproteins of insects share a common structural motif.

Elucidation of the secondary structure of the exchangeable apolipoproteins has been hindered by the difficulty in producing crystals suitable for X-ray spectrographic analyses. Consequently, in order to analyze potential structure-function relationships in the family of insect exchangeable apolipoproteins, apolipophorins-III (apoLps-III), two apoLps-III cDNA clones, one from the palo verde beet...

Concise synthesis of an antifeedant sesquiterpene against Locusta migratoria.

A concise synthesis of (1S*,3R*,6R*)-1-hydroxy-7(14),10-bisaboladien-4-one, an antifeedant against the locust Locusta migratoria isolated from the Japanese cedar Cryptomeria japonica, was achieved by starting from 4-hydroxy-2-cyclohexenone.
