amyloid peptide AAKLVFF was expressed as a His-tagged fusion protein with the immunoglobulin-binding domain B1 of streptococcal protein G (GB1), a small (56 residues), stable, single-domain protein. It is shown that expression of this model amyloid peptide is possible and is not hindered by aggregation. Formylation side reactions during the CNBr cleavage are investigated via synthesis of selectively formylated
模型淀粉样蛋白肽AAKLVFF表达为带有His标签的融合蛋白,具有链球菌蛋白G(GB1)的免疫球蛋白结合结构域B1,这是一个小的(56个残基)稳定的单结构域蛋白。已经表明该模型淀粉样蛋白肽的表达是可能的,并且不受聚集的阻碍。通过选择性甲酰化肽的合成,研究了CNBr裂解过程中的甲酰化副反应。
