Plastocyanin, like many other metalloproteins, does not undergo reversible folding, which is thought to be due to an irreversible conformational change in the copper-binding site. Moreover, apoplastocyanin's ability to adopt a native tertiary structure is highly salt-dependent, and even in high salt, it has an irreversible thermal denaturation. Here, we report a designed apoplastocyanin variant, PCV, that is well folded and has reversible folding in both high and low salt conditions. This variant provides a tractable model for understanding and designing protein β-sheets.
