英文摘要Histidine usually exists in three different forms (including biprotonated species, neutral tau and pi tautomers) at physiological pH in biological systems. The different protonation and tautomerization states of histidine can be characteristically determined by C-13 and N-15 chemical shifts of imidazole ring. In this work, solid-state NMR techniques were developed for spectral editing of C-13 and N-15 sites in histidine imidazole ring, which provides a benchmark to distinguish the existing forms of histidine. The selections of C-13(gamma), C-13(delta 2), N-15(delta 1), and N-15(epsilon 2) sites were successfully achieved based on one-bond homo- and hetero-nuclear dipole interactions. Moreover, it was demonstrated that H-1, C-13, and 15 chemical shifts were roughly linearly correlated with the corresponding atomic charge in histidine imidazole ring by theoretical calculations. Accordingly, the H-1, C-13 and N-15 chemical shifts variation in different protonation and tautomerization states could be ascribed to the atomic charge change due to proton transfer in biological process.
