The small protein MtrI blocks the Na+ binding subunit MtrCDE, bascially forming a plug for the channel. This could be important to prevent sodium leakage, when the complex gets damaged by oxygen.

Tristan could show this by pull-down experiments. Irrespective of the growth condition, the oxygen sensitive behaviour was present.

This is a showcase study how small ORF proteins can regulate a central bioenergetic machinery. MtrI, binds here in a oxygen sensitive manner to the methyltransferase shuttle domain of MtrA.

A) Diagram showing how EtfD transfers electrons from beta oxidation to the menaquinol pool in the membrane, linking beta oxidation to oxidative phosphorylation in mycobacteria.
B) A growth curve showing the Mycobacterium smegmatis lacking EtfD can grow when glucose is provided as the carbon source, but has a slight growth delay. Complementing the โˆ†etfD strain with M. tuberculosis on a plasmid rescues the defect.
C) A growth curve showing that โˆ†etfD M. smegmatis cannot grow on medium where the fatty acid oleic acid is the only carbon source. A plasmid with with M. tuberculosis EtfD rescues the defect.

EtfD links beta oxidation to OxPhos in mycobacteria - recent work suggests that targeting EtfD could shorten #tubeculosis treatment.
But how does EtfD work? And how can you assay its activity?
In his final PhD manuscript @courbongautier.bsky.social provides answers!
