Experimental evidence for the correlation of bond distances in peptide groups detected in ultrahigh-resolution protein structures
The structural analysis of a deamidated derivative of ribonuclease A, determined at 0.87 Angstrom resolution, reveals a highly significant negative correlation between CN and CO bond distances in peptide groups. This trend, i.e. the CO bond lengthens when the CN bond shortens, is also found in seven out of eight protein structures, determined at ultrahigh resolution (
