From: aes, the gene encoding the esterase B in Escherichia coli, is a powerful phylogenetic marker of the species

Figure 4

Models of the Aes protein variants. Of the 38 polymorphic sites identified, only the 24 sites at the protein surface are represented. Polymorphic sites are in green for carboxylesterase type B1 and red for type B2. The views A and B correspond to two opposite faces of the structure obtained by a rotation of 180° around the Y axis. Images were generated using PMG [57].
