Abstract

Tremendous effort has been dedicated to the design and assembly of bioinspired protein-based architectures with potential applications in drug delivery, tissue engineering, biosensing, and bioimaging. Here, we describe our strategy to generate fibers and bionanocomposites using the coiled-coil domain of cartilage oligomeric matrix protein (COMPcc). Our construct, Q, engineered by swapping particular regions of COMPcc to optimize surface charge, self-assembles to form nanofibers. The Q protein nanofibers can efficiently bind curcumin to form robust mesofibers that can be potentially used for drug delivery and biomedical applications. In addition, using the same Q protein, we describe the biotemplation of gold nanoparticles (AuNP) in the presence and absence of the hexahistidine tag (His-tag). The Q bearing His-tag·AuNP (Q·AuNP) readily deposits on electrode surfaces, while Q without His-tag·AuNP (Qx·AuNP) stabilizes the soluble protein·gold bionanocomposites for several days without aggregating.
