Shape of the binding site of Candida antarctica lipase A, Bacillus subtilis deacetylase and Candida rugosa lipase. (a) Orientation of the cross-sections which are planes perpendicular to the paper plane and indicated by a straight line. The direction of the view is indicated by an arrow. Shape of the binding sites is displayed in side, front and top view for (b) Candida antarctica lipase A, (c) Bacillus subtilis deacetylase, and (d) Candida rugosa lipase. A model of the acyl moiety of the substrate is displayed, the alcohol moiety is not shown for clarity. The position of the lid in a closed state for Candida antarctica lipase A and Candida rugosa lipase is indicated.
