Abstract

Supramolecular assembly of proteins on surfaces and vesicles was investigated by site-selective incorporation of a supramolecular guest element on proteins. Fluorescent proteins were site-selectively labeled with bisadamantane by SNAP-tag technology. The assembly of the bisadamantane functionalized SNAP-fusion proteins on cyclodextrin-coated surfaces yielded stable monolayers. The binding of the fusion proteins is specific and occurs with an affinity in the order of 106 M−1 as determined by surface plasmon resonance. Reversible micropatterns of the fusion proteins on micropatterned cyclodextrin surfaces were visualized by using fluorescence microscopy. Furthermore, the guest-functionalized proteins could be assembled out of solution specifically onto the surface of cyclodextrin vesicles. The SNAP-tag labeling of proteins thus allows for assembly of modified proteins through a host–guest interaction on different surfaces. This provides a new strategy in fabricating protein patterns on surfaces and takes advantage of the high labeling efficiency of the SNAP-tag with designed supramolecular elements
