Fig. 3.

Predicted metabolic pathways of phylotype Rs-D17. Periplasm (green) and cytoplasm (yellow) are shown bounded by outer and inner membranes, respectively. Blue, synthesized amino acids; red, cofactors. Compounds that must be imported are shown in pale colors. Nonfunctional pathways and transporters comprising pseudogenes are marked with red X's. Arrows with broken lines indicate diffusion or transport via some unidentified apparatus. ABC, ATP-binding cassette type transporter; msc, mechanosensitive channel; FAD, flavin adenine dinucleotide; SAM, S-adenosylmethionine; THF, tetrahydrofolate.
