Membrane tension lowering induced by protein activity

Soft Condensed Matter 2009-02-18 v2 Other Condensed Matter

Abstract

We present measurements of the fluctuation spectrum of giant vesicles containing bacteriorhodopsin (BR) pumps using video-microscopy. When the pumps are activated, we observe a significant increase of the fluctuations in the low wavevector region, which we interpret as due to a lowering of the effective tension of the membrane.
