Poster 117: Maggie Brueggemeyer – Towards Identifying the Signaling Partner of Photoactive Yellow Protein

Faculty mentor: Matthew Kieber-Emmons

Photoactive yellow protein (PYP), a light sensing protein found in Halorhodospira halophila, undergoes a unique structural change in response to blue light. PYP is believed to play a role in signaling the negative phototactic behavior of the bacteria; however, its signaling partner has not been identified. This work describes the adaptation of the Bacterial Adenylate Cyclase Two-Hybrid method to test the interactions of PYP with potential partner proteins and elucidate its signaling mechanism.
