Crystallography cell membrane

  • How do you determine membrane proteins?

    X-ray crystallography, nuclear magnetic resonance spectroscopy (NMR), and cryogenic electron microscopy (cryo-EM) are the main techniques that have been used to determine the .

  • Why is it difficult to crystalize membrane proteins?

    Their surface is relatively hydrophobic and they can only be extracted from the cell membrane with detergents.
    They are also often flexible and unstable.
    This leads to challenges at all levels, including expression, solubilisation, purification, crystallisation, data collection and structure solution..

Electron crystallography is the only structural biology technique in which the membrane protein of interest is crystallized within the context of a membrane and from which atomic resolution structures can emerge detailing the structures of both protein and lipid (Reichow and Gonen, 2009).
In this regard, X-ray crystallography has been the most widely used technique for determining the high-resolution 3D structures of membrane proteins. However, 

Can X-ray crystallography clone membrane proteins?

Here, we present methods from our work that outline our general pipeline from cloning to structure determination of membrane proteins, with a focus on using X-ray crystallography, which still yields ~90% of all structures being deposited into the Protein Data Bank

What are membrane protein crystallography protocols?

Protocols for membrane protein crystallography are most often found accompanying the publication of specific targets

In these instances, the scope of a given protocol is generally limited to one particular protein

What is protein crystallography used for?

Protein crystallography is used to generate atomic resolution structures of protein molecules

These structures provide information about biological function, mechanism and interaction of a protein with substrates or effectors including DNA, RNA, cofactors or other small molecules, ions and other proteins
