From: Structural analysis of Wss1 protein from saccharomyces cerevisiae
The crystal structure of ScWss121-148 (PDB: 5XBN). (A) The overall structure of ScWss121-148 with secondary structure elements labeled. The helices are shown in cyan, sheets in purple, loops in salmon and zinc ion in orange. The molecular surface of the domain is shown in transparent gray. (B) Close-up view of the active site, composed of His-115, His-119, His-125, and a zinc ion (orange sphere) in the center, accompanied by Glu-116 as well as a water molecule (blue sphere) between the zinc ion and Glu-116. The 2Fo-Fc electron density map (blue) is contoured to 1σ, whereas the Fo-Fc density map (red) for the Zinc ion is contoured to 3σ.
