Exchange Broadening

<div> <div> <div> <p>The zero- and double-quantum methyl TROSY Hahn-echo and the methyl <sup>1</sup>H-<sup>1</sup>H dipole- dipole cross-correlation nuclear magnetic resonance experiments enable estimation of multiple quantum chemical exchange broadening in methyl groups in proteins. The two relaxation rate constants are established to be linearly dependent using molecular dynamics simulations and empirical analysis of experimental data. This relationship allows chemical exchange broadening to be recognized as an increase in the Hahn-echo relaxation rate constant. The approach is illustrated by analyzing relaxation data collected at three temperatures for <i>E. coli </i>ribonuclease HI and by analyzing relaxation data collected for different cofactor and substrate complexes of <i>E. coli </i>AlkB. </p> </div> </div> </div>

Quantitative Examination

Chapter 6 offers a quantitative examination of the commercial development of Livorno, showing how it plugged local and regional exchange networks into the currents of global commerce. Livorno was at the epicenter of the reorganization of maritime trade in the Tyrrhenian and throughout the Mediterranean. Despite dense connections between north-central Italy and the free port, however, international commerce did not substantially affect productive relations in the hinterland. North-central Italy remained an autonomous region; rather than a colonial outpost subservient to northern capitalism, Livorno was a large marketplace connecting otherwise distinct economies. The Tuscan city’s success in organizing trade eventually provoked a competitive response by neighboring ports.
