Coexistence of two distinct versions of O-antigen polymerase, Wzy-alpha and Wzy-beta, in Pseudomonas aeruginosa serogroup O2 and their contributions to cell surface diversity.

Abstract excerpt

Assembly of B-band lipopolysaccharide (LPS) in Pseudomonas aeruginosa follows a Wzy-dependent pathway, requiring the O-antigen polymerase Wzy and other proteins. The peptide sequences of the wzy(alpha) product from strains of serotypes O2, O5, and O16 are identical, but the O units in O5 are alph...
