9.B.27.2.1
The YghB protein of 219aas and 5-6 TMSs. When both YghB and YqjA (TC# 9.b.27.2.2) are mutated, cells become alkaline tolerant and resistant to dyes and antibiotics, and a cell division defect is observed (Thompkins et al., 2008).  The YqjA protein is 60% identical to YghB, and these two act synergistically to maintain a normal pmf (Kumar and Doerrler 2015). Both of these proteins can replace a deleted DedA protein, DbcA, in Burkholderia thailandensis (Panta et al. 2019).
