Figure 4

Schematic representation of the solved or predicted tertiary structures of P1-C123 (a), WapA-AgA (b), and Smu_63c (c). The illustration of C123 is based on the solved crystal structure37 (PDB id:3QE5). The predicted structures of AgA and Smu_63C were determined using I-TASSER38. Blue to red rainbow coloring indicates progression from N- to C-termini.
