FIG 1 — OafA and OafB are membrane-bound O-acetyltransferases that acetylate the O-antigen of Salmonella. (A) Schematic representation of OafA and OafB functional (colored) and transmembrane (shaded) domains predicted by InterPro and TMHMM, respectively. C-term constructs used for in vitro characterization are indicated below the protein. (B) Proposed mechanism of action of O-antigen acetyltransferases during maturation of the LPS in the periplasm using OafA as an example. AT3, InterPro IPR002656; SGNH, InterPro IPR013830.
