Out now: ABC transporters like lipids - so do we! The second publication on an active ABC transporter in Salipro® in a month - this time from the Tidow lab in Hamburg, Germany - link to publication : https://www.degruyter.com/view/j/bchm.ahead-of-print/hsz-2019-0171/hsz-2019-0171.xml
Membrane protein research suffers from the drawback that detergents, which are commonly used to solubilize integral membrane proteins (IMPs), often lead to protein instability and reduced activity. Recently, lipid nanodiscs (NDs) and saposin-lipoprotein particles (Salipro) have emerged as alternative carrier systems that keep membrane proteins in a native-like lipidic solution environment and are suitable for biophysical and structural studies. Here, we systematically compare nanodiscs and Salipros with respect to long-term stability as well as activity and stability of the incorporated membrane protein using the ABC transporter MsbA as model system.
