2.A.103.1.1
Cell division protein, FtsW.  May flip lipid II (involved in cell wall synthesis) across the cytoplasmic membrane.  R145 and K153 in TMS 4 (of 10) are esesential for this transport activity (Mohammadi et al. 2014).  There is some controversy about this transport function (Young 2014; Sham et al. 2014).  See TC#2.A.66.4.3 for the alternative explanation.
