摘要: 本文利用水质子的选择性弛豫试剂,通过对乙肝病毒e抗原中一个预测的抗原决定簇(HBeAg P3肽)在水溶液中的构象研究,对NMR实验中水峰的抑制进行了新的探索,并完成了HBeAg P3肽的谱峰指定。

Abstract: In this paper we have applied a new procedure to suppress the huge water reso-nanee in the NMR study of HBeAg P3 peptide which is predicted to be an ep itope of hepatitis Be antigens. Adding water selective relaxation reagents, we have success-fully carried out the 1D and 2D NMR experiments of HBeAg P3 pep tide in water solution and accomplished the resonanee assignments of the P3 peptide.
