Artificial Metalloproteins for Binding and Stabilization of a Semiquinone Radical

A coordination study of first-row transition-metal ions to bipyridine alanine (bpyA) incorporated into the lactococcal multidrug resistance regulator (LmrR) scaffold is reported. The designed metalloproteins were shown to bind and stabilize the di-tert-butylsemiquinone radical (DTB-SQ) in water, allowing for the first resonance Raman characterization of this radical species in water.
