Cover illustration: The active site of P. fluorescens aryl esterase is formed by catalytic residues Ser94 and His251 (red) with the N atoms of Trp128 and Met95 (CPK colors) forming the oxyanion hole. Val121 (magenta) marks the acyl binding site and Phe93 (yellow) marks the binding site of the alcohol moiety of the substrate (p. 1237). |
