Toxoflavin Lyase Requires a Novel 1-His-2-Carboxylate Facial Triad,

High resolution crystal structures are reported for apo, holo, and substrate-bound forms of a toxoflavin-degrading metalloenzyme (TflA). In addition, the degradation reaction is shown to be dependent on oxygen, Mn(II), and dithiothreitol in vitro. Despite its low sequence identity with proteins of k...
