From: Sac Pox from the thermoacidophilic crenarchaeon Sulfolobus acidocaldarius is a proficient lactonase
Structural model of Sac Pox. A. Structural superposition of Sso Pox structure (2VC5; grey) and the Sac Pox model (green). Cobalt, iron and the catalytic water molecule are respectively represented by pink, orange and red spheres. Bimetallic center coordinating residues are represented as sticks. B. Active site view of superimposed Sso Pox structure (grey) and the Sac Pox model (green). Several active site residues are represented as sticks. Numbering is made according to Sac Pox sequence.
