About this project: This illustration was created to illuminate the unique structure known as the “Z-ring” and its associated proteins of the E. coli bacterium, which support and regulate cell division. Published as a 2-page spread (in “Artifact”, a feature that highlights striking, attention-grabbing images of new discoveries found or developed at Hopkins), it illustrates the peptidoglycan (PG) protein structure of the divisome and elongasome protein complexes (ZapA-ZapB-MatP). The divisome and elongasome are responsible for PG synthesis during cell division and elongation, respectively. FtsZ assembles into the Z-ring that determines the division plane. FtsA assists in the formation of the Z-ring, recruits downstream division proteins to the Z-ring to generate the divisome that divides the cell, and is involved in coordinating cell wall synthesis during cytokinesis.
