Graphical Abstract

Amphipathic DNA origami structures were engineered, which have a flat membrane-binding interface decorated with cholesterol-derived anchors and sticky oligonucleotide overhangs enabling formation of ordered arrays on a membrane. Such DNA origami structures are capable of deforming free-standing lipid membranes (see picture), mimicking the biological activity of coat-forming proteins.

Abstract

We report a synthetic biology-inspired approach for the engineering of amphipathic DNA origami structures as membrane-scaffolding tools. The structures have a flat membrane-binding interface decorated with cholesterol-derived anchors. Sticky oligonucleotide overhangs on their side facets enable lateral interactions leading to the formation of ordered arrays on the membrane. Such a tight and regular arrangement makes our DNA origami capable of deforming free-standing lipid membranes, mimicking the biological activity of coat-forming proteins, for example, from the I-/F-BAR family.
