Grafted biomembranes containing membrane proteins--the case of the leucine transporter

Soft Matter. 2015 Oct 21;11(39):7707-11. doi: 10.1039/c5sm01490e. Epub 2015 Sep 1.

Abstract

Here, we bind the sodium dependent amino acid transporter on nitrilotriacetic acid/polyethylene glycol functionalized gold sensors in detergents and perform a detergent-lipid exchange with phosphatidylcholine. We characterize the LeuT structure in the adsorbed film by magnetic contrast neutron reflection using the predicted model from molecular dynamic simulations.
