Fig 1. Structural prediction of the PlyE146 C-terminal domain and sequence alignment with P307.

The C-terminal domain of PlyE146 (P146) assumes a hairpin-like di-alpha helical structure linked by a flexible unstructured region (A) and shares 68% identity with PF307 (B). In blue are conserved amino acids, in yellow positively-charged amino acids and in green conserved, positively-charged amino acids.
