Introduction

<

Escherichia coli (E. coli)is an inhabitant of the human intestine and a model organism for gram-negative bacteria (http://en.wikipedia.org/wiki/Escherichia_coli). While it has been long assumed that prokaryotes lack the sophistical intracellular architecture of eukaryotic cells and are unorganized bags of cytoplasm surrounded by a membrane, more recent research has shown that prokaryotes do indeed have cytoplasmic organization with the nucleoid and various proteins restricted to certain areas. A fundamental issue for cells is how to target protein to their correct cellular location. In gram-negative bacteria proteins may need to be selectively localized to the inner membrane, outer membrane, periplasm or secreted outside the cell (Figure 1). Proteins that fail to reach their correct localization will not function appropriately. For example, the Lac Y gene product, lactose permease, must be present in the inner membrane to allow lactose entry into the cytoplasm.
