Abstract

The protonation state of the deazaflavin dependent nitroreductase (Ddn) enzyme bound cofactor F₄₂₀ was investigated using UV-visible spectroscopy and computational simulations. The reduced cofactor F₄₂₀H₂ was determined to be present in its deprotonated state in the holoenzyme form. The mechanistic implications of these findings are discussed.
