Electrostatic surface of the Acel_2062 protein. The electrostatic surface potential representation of the active pocket was made with a Delphi embedded JCSG script, (kindly provided by Qingping Xu) and displayed using Pymol. Negative electrostatic potential predominates over the entire surface of Acel_2062. The putative active site residues (Glu96 and Tyr113) and zinc ligands are (His95, His99 and Asp105) are shown in sticks. The color scale is in units of kT/e ranging from −10 to +10.
