The ability to thermally trigger a conformational changeand collapse in a constituent resilin-like protein (RLP) providesthe opportunity to build, and eventually move, a bundlemer nanostructure.

Bundlemer peptides can still assemble into coiled coil bundles even with RLPs attached to all four constituent peptides in each bundle. This is a clear demonstration that biosynthesis can be used for bundlemer building block production for future study.

• This ability affords a mechanism for the formation (and disassembly) of bundlemer-based nanomaterials through temperature responsive proteins
• The ability to thermally trigger a conformational change/collapse in a constituent polymer/protein provides the opportunity to purposefully move a bundlemer nanostructure in future Aim 2 efforts.
• This is a major step towards success of Aim 2 in which nanostructures will be purposefully moved. The thermal collapse of the RLP can be used to both form structure (Aim 1) and to move structure (Aim 2).
• The successful biosynthesis from E. Coli of the bundlemer peptide and RLP constructs clearly affords future success in peptide/protein production with biosynthesis for scale up and study.
