Fatty Acid Triangulation in Albumins Using a Landmark Spin Label

Optimal Landmark Selection for Triangulation

A mobile robot can identify its own position relative to a global environment model by using triangulation based on three landmarks in the environment. It is shown that this procedure may be very sensitive to noise depending on spatial landmark connguration, and relative position between robot and landmarks. A general analysis is presented which permits prediction of the uncertainty in the tria...

Fatty acid pH titration and the selectivity of interaction with extrinsic proteins in dimyristoylphosphatidylglycerol dispersions. Spin label ESR studies

The effects of pH titration on the ESR spectra of 5-(4,4-dimethyioxazolidine-N-oxyl) stearic acid in bilayers of dimyristoyi phosphatidylglyceroi complexed with either myelin basic protein, apocytochrome c, cytochrome c or lysozyme have been studied. Binding of the protein increases the outer hyperfine splitting of the stearic acid spin label to an extent which depends on the protonation state ...

A nitroxide-maleimide spin label.

was chemically bonded to poly-L-lysine and to bovine serum albumin (BSA) and showed a paramagnetic resonance spectrum that was sensitive to known structural changes in these molecules, such as those produced by changes in pH.2 This nitroxide-isocyanate is unfortunately not an ideal spin-labeling reagent since it is unstable and thus difficult to purify, and moreover the isocyanate group is rapi...

Bovine serum albumin. Study of the fatty acid and steroid binding sites using spin-labeled lipids.

Three spin-labeled derivatives of stearic acid and two derivatives of palmitic acid have been used to study the structure of the strong fatty acid binding site of bovine serum albumin. The steroid and indole binding sites have been studied using spin-labeled derivatives of androstol and indole, respectively. Paramagnetic resonance and fluorescence quenching data suggest that the fatty acid, ste...
