Cysteine and methionine biosynthesis pathways in E. coli and S. enterica serovar Typhimurium and the responsible genes. Activation by CysB (+B) or MetR (+R) and repression by MetJ (−) are indicated in superscript. The genes from this pathway with homologues in the L. lactis IL1403 genome sequence are underlined. The conversion of cystathionine to cysteine is not described for E. coli. CBL from L. lactis is able to catalyze this reaction in vitro (1).
