S.E. Williams et al., "Hemoxygenase-2 is an oxygen sensor for a calcium-sensitive potassium channel,"
It was known that [Big K+] channels are sensitive to oxygen, but the mechanism of sensing oxygen has remained elusive. It appears now that hemoxygenase-2 is in a complex with BK channels, and that carbon monoxide, a product of HO-2 activity, activates the channel.

It is always intriguing to see how nature succeeds to put new functions on old frameworks. In this paper, the authors suggest how a promiscuous protein function evolves without affecting the primary function.
