Description
Matthias Ostermeier and co-authors vary the dose of a membrane-shaping protein in a photosynthetic bacterium and watch its light-harvesting sheets change, in a 2026 study. The protein, CurT, bends the membranes where photosynthesis happens and gathers them into meeting zones. What those zones do for the cell was unclear.
They grow mutants of the bacterium Synechocystis with CurT levels from none to excess. A little CurT already restores the meeting zones and partly revives light system performance and growth. More CurT adds late growth gains that do not track the light system's activity. The link between dose and structure bends like a threshold curve, not a straight line. CurT thus acts as a dose-set dial for membrane design.
