摘要：

(Figure Presented) Get a grip! The strategy of single-molecule mechanical unfolding of multimodular proteins is extended to the investigation of any chemical bond by an appropriately tailored, comblike polymer bearing multiple instances of any desired chemical interaction or bond to be studied along its linear chain. This approach is used to study the Ni-(His)n-NTA complex (see picture: red, Ni-NTA; green, His tag; His = histidine; NTA = nitrilotriacetate). © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
