NMR STRUCTURE OF RIBONUCLEASE T1, 34 STRUCTURES
Overview
Limits of NMR structure determination using multidimensional NMR, spectroscopy, variable target function calculations and relaxation matrix, analysis were explored using the model protein ribonuclease T1 (RNase T1)., The enzyme consists of 104 amino acid residues and has a molecular mass of, approximately 11 kDa. Primary experimental data comprise 1856 assigned NOE, intensities, 493 3J coupling constants and 62 values of amid proton, exchange rates. From these data, 2580 distance bounds, 168 allowed ranges, for torsional angles and stereospecific assignments for 75% of, beta-methylene protons as well as for 80% of diastereotopic methyl groups, were derived. Whenever possible, the distance restraints were refined in a, relaxation matrix analysis including amid proton exchange data for, ... [(full description)]
