Abstract

The Tat system is a recently-discovered bacterial protein export pathway. This system has the remarkable ability of being able to transport folded polypeptides across the cytoplasmic membrane without rendering the membrane ion-permeable. The Tat preprotein translocase of Escherichia coli is an approximately 600kDa integral membrane complex containing an estimated 50 polypeptide chains. Building on our recent success in imaging a Tat complex by negative strain EM we aim to (1) analyse the Tat complex by single particle EM methods (2) further develop our overexpression and purification strategies to enable a concerted attempt to grow 2D and 3D crystals of the Tat complex suitable for medium to high resolution structure determination.
