Toward protein encapsulation by a synthetic host, we synthesized an ubiquitin-dangled ligand, a potential precursor of a nanoscale coordination cage. The key step is the addition of a C-terminal Cys76 SH group, which was introduced by Gly76Cys mutation, to a maleimide acceptor on the ligand. The C-terminal mutation and the SH addition to the ligand did not damage the ubiquitin moiety at all, neither structurally nor conformationally.
我们合成了一种由合成宿主包裹蛋白质的途径,即一个悬挂着泛素的配体,它可能是一种纳米级配位笼的前体。关键步骤是将C末端的Cys76 SH基团(通过Gly76Cys突变引入)添加到配体上的马来酰亚胺受体。C末端突变和SH添加到配体中对泛素的结构或构象没有造成任何损害。
