Schematic representation of EPS repeating unit biosynthesis and polymerization in R. leguminosarum. Based on 8, 36, 79–82, 84–87, 89–91. Question marks indicate putative, based on the results of homology searches, function of PssR, PssM and other Pss/Exo proteins. Colour marks of the proteins respond to those in Fig. 2. Abbreviations used: Glc, glucose; GlcA, glucuronic acid; Gal, galactose; Ac, acetate; Pyr, pyruvate; IM, inner membrane.
