In 1628, the Swedish warship Vasa capsized on her maiden voyage and sank in the Stockholm harbor. The ship was recovered in 1961 and, after polyethylene glycol (PEG) impregnation, it was displayed in the Vasa museum. Chemical investigations of the Vasa were undertaken in 2000, and extensive ...

Ankyrin repeat (AR) proteins are composed of tandem repeats of a basic structural motif of ca. 33 amino acid residues that form a β-turn followed by two antiparallel α-helices. Multiple repeats stack together in a modular fashion to form a scaffold that is ideally suited for the presentation ...
