Figure 3From: Structural insights into the substrate tunnel of Saccharomyces cerevisiae carbonic anhydrase Nce103The 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.Back to article page
