#Computer-Designed Rocker Protein Worlds First To Biomimic Ion Transport For the first time, scientists recreated the biological function of substrate transportation across the cell membranes by computationally designing a transporter protein.
The designed protein, dubbed Rocker, was shown to transport ions across the membrane, a process crucial to cell and organismal survival in various functions,
The engineered Rocker protein acts like a tiny gate, designed so that zinc ions and protons can flow in a controlled way across the lipid-membrane barrier around the cell-like vesicle.
Rocker was designed to perform this function by doing one thing ockingbetween two different shapes, or conformations.
Rocker changes its shape to close off the pocket, while opening up the second pocket near the other side of the membrane.
The catch is that Rocker can have both pockets bind the ions at the same time, nor permit the cavity to open all the way through the membrane at one time
and dynamic nature of Rocker embedded in lipid and in detergent by using nuclear magnetic resonance (NMR).
Also, Rocker reconstituted in membrane vesicles was tested to show that it really pushed zinc ions from one side of the membrane to the other,
