FIGURE 2.

Model of the Pseudomonas aeruginosa alginate biosynthetic complex. Proteins involved in polymerization are colored blue, the alginate lyase red, the epimerase orange, and proteins involved in acetylation green. The names of proteins assumed to be part of the alginate polymerization and transport complex are written using black letters. Alginate is depicted as a text string; “a” denotes acetyl-groups.
