Serratia symbiotica strain SCt-VLC metabolic reconstruction. Serratia symbiotica metabolic reconstruction as done by PathwayTools. Intact pathways are shown in black lines, unclear pathways are shown in gray lines, and the ones that are already represented elsewhere with another line are shown as dotted lines. Exporters are represented with green ovals, whereas exporters and exporters/importers are represented with blue ovals. EAAs and non-EAAs are shown in red and purple lettering, respectively. Gray compounds represent those for which biosynthesis cannot be accounted for by the genomic data of S. symbiotica SCt-VLC. Formate dehydrogenase-O is shown semitransparent given that the pseudogenization of one of its genes is unclear, it being a selenoprotein.
