CCL: Proline backbone nitrogen pKa/pKb



 Sent to CCL by: Massimiliano Porrini [M.Porrini[a]ed.ac.uk]
 Hi all,
 I hope my following question is not that far from the scope of this
 mailing list.
 Does anybody know any reference where I could get the value of the pK_a
 (or related pK_b) of the backbone nitrogen of proline residue
 as a part of a peptide/protein (not the lone proline) ?
 Any hint would be really appreciated.
 Best,
