Fig. 3

Three-dimensional structures of PGLs from different PLs families. A–C. The PGL Bsp165PelA, PelE and AcPel from the PL1 family all display typical β-helical structure. The β sheets (PB1, PB2, PB3), N-terminal and C-terminal of Bsp165PelA are marked in Fig. 3A. The white spheres in Fig. 3C are calcium ion. D, E The PGLPelA and Pel10Acm from the PL10 family are (α-α)3-barrel structures. The green and white spheres in Fig. 3D are chlorine and mercury ions, respectively. F The PL 2 family PGL YePL2A from Yersinia enterocolitica presents a rare (α-α)7-barrel structure; the corresponding PDB is marked below each structure diagram
