Rhomboid Protease Cuts Unstable Target Protein (image) Johns Hopkins Medicine Share Print E-Mail Caption The membrane encourages a coil to form in a target protein (left, pink and yellow) and helps keep the gate (pale blue) of the rhomboid protease (deep blue) from swinging open too far (center). When the target protein enters the watery interior of the rhomboid protease, the upper section of its coil (yellow) falls apart and gets cut (right).
