radiation) of proton-bound peptide complexes leads to water elimination and the formation of longer amino acid chains. Thus, it appears that proton-bound dimers are long-lived intermediates along the pathway to peptide formation. Product specificity can be controlled by selection of specific complexes and the incorporation of blocking groups at the N- or C-termini. The product peptide sequences are confirmed
质子结合肽复合物的光激发(使用 157 nm 真空紫外线辐射)导致水消除和更长的氨基酸链的形成。因此,质子结合的二聚体似乎是肽形成途径中的长寿命中间体。产品特异性可以通过选择特定的复合物和在 N 或 C 端加入封闭基团来控制。使用碰撞诱导解离确认产物肽序列。
