The active site of Nce103. A) Electron density map of the acetate molecule. The 2Fo-Fc map is colored in blue and contoured at 1.5 σ and the Fo-Fc map is colored in green and contoured at 3.0 σ. B) The coordinating bonds of the zinc ion and the hydrogen bonds stabilizing the acetate molecule are illustrated.
