“…Bargossi et al . () demonstrated that the genetic organization and nucleotide sequence of the tyrDC cluster was highly conserved in the enterococcal strains E. faecalis EF37 and ATCC 29212. In particular, the cluster sequence of these strains shares the same genetic organization, which comprises the four predictable complete open reading frames corresponding to the genes tyrS , tyrDC , tyrP and nhaC .…”
