Disease relevance of ftsL

  • The third B. subtilis gene, yllD, is essential, as is the correspondingly positioned ftsL gene of E. coli [1].

High impact information on ftsL

  • Repression of ftsL in a strain engineered to carry a conditional promoter results in cell filamentation, with a near immediate arrest of cell division [2].
  • TnphoA topological analysis and fractionation of alkaline phosphatase fusion proteins indicated that the ftsL gene product is a 13.6-kDa cytoplasmic membrane protein with a cytoplasmic amino terminus, a single membrane-spanning segment, and a periplasmic carboxy terminus [3].
  • This gene, which we named ftsL, was detected through characterization of TnphoA insertions in a plasmid containing this chromosomal region [3].
