| 摘 要： | 研究蛋白质与金属离子之间的相互作用的本质一直是生物学家感兴趣的课题。但蛋白结构的复杂性使得二者之间相互作用的研究难度很大，常选用氨基酸或小肽作为模型化合物进行研究^1-4]。目前该方法的研究甩缺乏系统性。

| Abstract: | Electrospray ionization(ESI) and tandem mass spectrometry have been used to investigate the gas phase interactions of five metal ions and seven dipeptides. For silver ion, two complexes( + and +) were obtained as well as the one complex ( +) for transition metal ions. Upon collision activation, there is an obvious difference in MS/MS data between metal ion complex and the protonated molecule. The fragment pathway of each complex is related to the structures of dipeptide and the nature of metal ion which suggest that there are several interaction between the metal ions and dipeptides in gas phase. |
