Spin Labeling of Surface Cysteines Using a Bromoacrylaldehyde Spin Label [PDF]

open access: yesApplied Magnetic Resonance, 2021
AbstractStructural investigations of proteins and their biological complexes are now frequently complemented by distance constraints between spin labeled cysteines generated using double electron–electron resonance (DEER) spectroscopy, via site directed spin labeling (SDSL).

Spin-labeled lipid A [PDF]

open access: yesAnalytical Biochemistry, 2008
Lipopolysaccharide (LPS), a major component of the outer membranes of gram-negative bacteria, is composed of a polysaccharide chain attached to a lipid A base that contains a disaccharide headgroup with two negative phosphate groups and at least four acyl chains.

Spin-labeled polyribonucleotides [PDF]

open access: yesNucleic Acids Research, 1980
Poly (U), poly (C) and poly (A) were spin labeled with N-(2,2,5,5-tetramethyl-3-carbonylpyrroline-1-oxyl)-imidazole. This spin label interacts selectively with 2' OH ribose groups of polynucleotides and does not modify the nucleic acid bases. The extent of spin labeling is not dependent upon the nature of the base and is entirely determined by rigidity

Spin-Labeled Neurospora Mitochondria

open access: yesBiophysical Journal, 1970
Spin-label studies were carried out on Neurospora mitochondria under in vivo and in vitro labeling conditions. A long-chained spin-labeled fatty acid was incorporated by Neurospora and was found in mitochondrial phospholipids. The molecular motion at various temperatures was different from that for the same spin label under in vitro labeling conditions.

Spin-labels in biochemistry

open access: yesBiochemical Society Transactions, 1985
and P-700 (Heathcote & Evans, 1981). The existence of a group of electron acceptors with a range of redox potentials which can be sequentially reduced by the appropriate lowtemperature illumination regimens suggests that these components form an electron-transport chain t o transfer electrons from the excited-state P-700 t o ferredoxin, allowing rapid ...

SPIN-LABELED TRANSFER RNA [PDF]

open access: yesProceedings of the National Academy of Sciences, 1969
The α-amino group of valyl-tRNA has been combined chemically with a nitroxide spin label through an amide linkage. This spin-labeled aminoacyl-tRNA has an electron paramagnetic resonance spectrum which reflects the mobility of the aminoacyl end of the tRNA molecule.

Arterial spin labeling in neuroimaging

open access: yesWorld Journal of Radiology, 2010
Arterial spin labeling (ASL) is a magnetic resonance imaging technique for measuring tissue perfusion using a freely diffusible intrinsic tracer. As compared with other perfusion techniques, ASL offers several advantages and is now available for routine clinical practice in many institutions. Its noninvasive nature and ability to quantitatively measure
