In silico analyses of PA1_Wzy. (A) Sequence alignment of Wzy. Identical residues are shown as white letters boxed in red, similar residues are written with black characters boxed in yellow. (B) Phylogenetic analysis. Wzy homologs belonging to different P. aeruginosa serotypes were subjected to phylogenetic analysis. The serotypes labeled in red and bold letters indicate that Wzy activity has been experimentally determined in these serotypes. Beta represents phage D3-coding Wzy that mediates β-linkage of O-antigen repeat unit. (C) Transmembrane topology analysis. Red: transmembrane helices. Blue: cytoplasmic loops. Pink: periplasmic loops.
