Transporter classification was taken from the work of Higgins, Saier, and Schneider (23, 49, 50). Transporters were identified by KAAS (the KEGG automatic annotation server). Transporter no. 1, ribose (rbsABCD); no. 2, d-xylose (xylFHG); no. 3, fructose (frcABC); no. 4, rhamnose (rhaPQST); no. 5, glycerol-3-phosphate (ugpABCE); no. 6, sorbitol/mannitol (smoEFGK); no. 7, α-glucoside (aglEFGK); no. 8, amino acids; no. 9, capsular polysaccharide (kpsEMT); no. 10, lipoprotein (lolCDE); no. 11, lipopolysaccharide (lptBFG). Gene designations are given in parentheses. Operons containing all expected genes are characterized by ”+”; operons that apparently lack genes are characterized by ”O.” GenBank accession numbers are as follows: Phaeobacter gallaeciensis 2.10, NZ_ABIE00000000; Roseobacter sp.
