Low-Barrier Hydrogen Bond between Phosphate and the Amide Group in Phosphopeptide

open access: yes, 2016
As the conversion between the monoionic (1) and diionic (2) form of the phosphate occurs, the phosphorylated peptides or proteins can not only cause the formation of a hydrogen bond between the phosphate group and the amide group but also change the ...
