Figure 10

Comparison of the active site of CcEstA, R61 DD-peptidase (3PTE), and PaPBP (2QMI).

(A) Ribbon diagram of enzyme active sites. Key residues (Ser and Lys in motif I, Tyr in motif II, and Histidine in motif III) in the active site are highlighted and shown as ball-and-stick model. (B) Molecular surfaces of the enzyme active site. Nucleophilic Ser is shown in red and other highly conserved residues (Lys, Tyr, and His) in the same color scheme with (A).
