O-antigen chain length is regulated by Wzz. LPS preparations from S. enterica serovar Typhimurium LT2 (WT) and its derivative wzz-null strains (CWG859 and CWG860) were analyzed by SDS-PAGE on a 4-12% Bis-Tris gradient gel and silver-stained. wzz genes were expressed in trans from pBAD-based plasmids in CWG860 and result in the production of long (L) and very long (VL) mode LPS as previously reported (16, 23, 29, 34, 44).
