13C labelled methyl alkylsulfonates are low cost and easily accessible methylatingagents. They were used as NMR probes, in association with DEPT 13C1H} NMR and 2D reversed 1H,13C} correlation NMR for the identification of nucleophilic residues of proteins. This labelling technique allows to visualize the nature of the reactive amino acids and to distinguish between lysine and histidine nucleaophilic
13 C标记的烷基磺酸甲酯是低成本且易于获得的甲基化剂。它们被用作NMR探针,与DEPT 13 C 1 H} NMR和2D反向 1 H,13 C}相关NMR一起用于鉴定蛋白质的亲核残基。这种标记技术可以可视化反应性氨基酸的性质,并可以区分赖氨酸和组氨酸的亲核残基。
