The WaaL O-antigen ligase of Rhizobium tropici CIAT 899. A, Kite-Dolittle hydrophobicity plots of Vibrio cholerae V194 and R. tropici CIAT 899 WaaL proteins. B, R. tropici CIAT 899 WaaL protein represented as a light gray arrow with predicted membrane-spanning regions indicated with dark grey boxes and the position of the Pfam PF04932 conserved domain indicated with a white box. C, Multiple sequence alignment showing conserved regions shared by WaaL proteins. D, Lipolysaccharide profiles of Rhizobium tropici CIAT 899 (wt), its waaL mutant (E4), and the complemented mutant (E4 + waaL).
