Membranes are obviously essential for the structural and biochemical properties of the cell, and membrane proteins make up a large portion of genomes of bacteria and other life. There is still very much we do not know about their functions, interactions and roles within the cell.

Comparative flux control through the cytoplasmic stages of cell wall biosynthesis
Gemma is interested in the membrane protein TatA which is involved in the Twin Arginine Translocase (Tat) pathway in bacteria. She is investigating how it forms a range of complexes and how these are involved in the Tat pathway.
