A CBI Molecule being studied in the University of Massachusetts Amherst Chemistry-Biology Interface Program at UMass Amherst and on display at the Molecular Playground.

T7 RNA polymerase is a a single sub-unit DNA dependent RNA polymerase from the T7 RNA bacteriophage. Like most RNA polymerase T7 RNA polymerase transcribes DNA through three phases -Initiation -Elongation -Termination

A bacterial chemotaxis receptor is an unusually long alpha-helical structure. The attractant molecule (the ligand) binds near the top of this picture and sends a signal across the membrane into the cell to control proteins that bind near the bottom. This is a model of the structure of the receptor based on experimental structures of pieces of related proteins.
