Disease relevance of rhaT

  • Cloning, mapping and gene product identification of rhaT from Escherichia coli K12 [1].
  • This strain was used to isolate a clone of Salmonella typhimurium DNA that encoded L-rhamnose-H+ transport activity, the gene for which, rhaT, was sequenced [2].

High impact information on rhaT


Biological context of rhaT

  • The sequence of the sodA-rhaC interval displayed a single ORF corresponding to rhaT, which is transcribed counterclockwise on the E. coli chromosome [4].
