Key result
Random mutagenesis reveals MscL channels tolerate heavy S1 mutation and sense tension near lipid headgroups.
Why the study?
Random mutagenesis combined with high-throughput functional screening was used to gain new insights into the structure and function of the Escherichia coli MscL channel.
Population
Escherichia coli mechanosensitive channel of large conductance (MscL)
Comparison
Mutated MscL variants vs wild-type channel function

Does not support clinical translation of bacterial channel data; leaves open applicability to cardiovascular mechanosensation.
Random mutagenesis of E. coli MscL reveals that the S1 helix is highly tolerant to mutation and suggests tension sensing occurs near the lipid bilayer headgroups.
Maurer et al. (2003) studied this question. Random mutagenesis was evaluated on Channel structure and function. Random mutagenesis of the E. coli MscL channel revealed that the S1 helix can be heavily mutated without altering function, and tension is sensed near the lipid headgroups.
