Yet, in contrast to nearly all other types of molecular building blocks, the designed self-assembly of proteins has largely been inaccessible because of the chemical and structural heterogeneity of protein surfaces. To circumvent the challenge of programming extensive non-covalent interactions to control protein self-assembly, we have previously exploited the directionality and strength of metal coordination interactions to guide the formation of closed, homoligomeric protein assemblies. Here, we extend this strategy to the generation of periodic protein arrays. We show that a monomeric protein with properly oriented coordination motifs on its surface can arrange, on metal binding, into one-dimensional nanotubes and two- or three-dimensional crystalline arrays with dimensions that collectively span nearly the entire nano- and micrometre scale. The assembly of these arrays is tuned predictably by external stimuli, such as metal concentration and pH.
