The composite active site of arylsulfatase B. The structure of arylsulfatase B is shown as a ribbon. Panel A the active site residue K145 is shown in yellow, the atoms lining the most conserved pockets are shown as brown spheres. Adjoining pockets are added in order of decreasing conservation starting from panel B where the atoms are shown as green spheres, to Panel C, where the atoms are shown as orange spheres and to Panel D, where the atoms are shown as pink spheres.
