(12 pts) The chemical shift is one of the most important experimental NMR parameters which becomes readily available at a very early stage of a protein NMR study. Amino acid chemical shifts are determined by the corresponding covalent structure (identity of amino acid; e.g. Gly vs. Ala or atom in an aromatic sidechain vs. atom in an aliphatic sidechain), the neighboring amino acids (flanking in the primary sequence), interactions with other amino acids through space (e.g. spatial vicinity in a folded protein). Shown below are the “fingerprint” 2D 1H-15N HSQC spectra of a protein acquired under two conditions (A and B). a) The resonances of which exactly atoms are correlated in a 2D 1H-15N HSQC experiment? (4 pts) b) Which of the two conditions (A and B) corresponds to non-native conditions (9M urea) and which to native conditions (0M urea)? Justify your answer (8 pts)
