Figure 8From: Bacterial variations on the methionine salvage pathwayVariety of gene organisation for the methionine salvage pathway in different bacteria. The organisation of the genes coding for the methionine salvage pathway is shown in several bacteria: B. subtilis, P. aeruginosa, X. fastidiosa, L. interrogans and T. tencongensis. The pathway is as described in Figure 1. Genes with the same function are indicated with the same color code. When a gene arrow is broken, this indicates that the function is the same, but that the gene product differs (enolase (MtnW) and phosphatase (MtnX) in B. subtilis, vs enolase-phosphatase (MtnC) in other organisms). The stem and loop symbol indicates the presence of a S-box riboswitch. In B. subtilis the enolase-phosphatase activity found in other organisms is replaced by two enzymes, a RuBisCO-like enolase and a phosphatase. In X. fastidiosa, downstream of the main operon on can see a truncated form of mtnK (broken arrow) requiring the presence of mtnP instead.Back to article page
