In this study we demonstrate that one of the previously uncharacterized homologs of MscS in E.
E. coli possess only one MscL type protein but six MscS homologs: MscS ( aa), MscK channel activities have been labeled to date: MscL, MscS and MscM.

Recordings from cells deleted for mscS and mscK (strain MJF; Table S1). E. coli has four homologs additional to MscS and MscK: YjeP ( aa). cells lacking MscL, MscS, and MscK can display – pS MscM.
The reasons that such channels are not seen in the E.
coli mutant strain MJF, which lacks the readily detectable MscS, MscK, and MscL channels, are.
The basis for these observations is unknown. A remarkable observation is that the YbdG mutant VA activity is apparently suppressed by coexpression with the wild-type subunit.
Genome analysis across the microbial and plant kingdoms has revealed the presence of multiple MscS homologs, but only rarely multiple MscL proteins 10 — S1 A and C. Functional design of bacterial mechanosensitive channels.

Members of these families can be found in Bacteriamany Archaeasome plants, fungi, and oomycetes 10 — 12 but are best studied in E. Pressure-sensitive ion channel in Escherichia coli. This influx produces increased tension in the membrane bilayer that gates MS channels, leading to transient formation of pores in the cell membrane 2 — 4.
