We have used a series of N-(1-oxyl-2,2,5,5-tetramethyl-3-pyrrolidinyl) maleimide spin labels of different length to label, covalently and selectively, the most reactive sulfhydryl groups of 70S ribosomal proteins of Escherichia coli. Under short periods of labeling (1--2 min), less than two

We have used the site-directed spectroscopies of time-resolved fluorescence resonance energy transfer (TR-FRET) and double electron-electron resonance (DEER), combined with complementary molecular dynamics (MD) simulations, to resolve the structure and dynamics of cardiac myosin-binding protein C (cMyBP-C), focusing on the

In a recent paper, Daveloose et al. (Daveloose, D., Fabre, G., Berleur, F., Testylier, G. and Letterrier, F. (1983) Biochim. Biophys. Acta 763, 41-49) described a technique to measure the internal microviscosity of erythrocytes using the spin label MAL-3 (2,2,5,5-tetramethyl-3-malimidopyrrolidinyl-N-oxyl)
