All cells have a cell membrane, made up of a lipid bilayer. Through this membrane sit the membrane proteins; a vital family of proteins which control how the cell interacts with its environment, and control passage of materials in and out of the cell. The family are challenging to study, as the process of crystallisation – the first step to determining a protein’s atomic structure – is incredibly difficult to perform with lipid soluble proteins. Researchers from Trinity College Dublin have now discovered the structure of the membrane protein, diacylglyerol kinase, DgkA, an enzyme found in bacterial cell membranes, using beamline I24 at Diamond Light Source.
