Superfamily: LuxQ periplasmic domain, N-terminal subdomain

Structural domains that comprise this superfamily share the structure of the N-terminus of the periplasmic domain in LuxQ, a sensor histidine kinase involved in quorum sensing in the marine bacterium Vibrio harveyi. Quorum sensing is process of bacterial cell-cell communication driven by secreted signaling molecules called autoinducers such as AI-2. The receptor for this autoinducer is LuxPQ, formed as a result of the association between LuxQ and LuxP, a periplasmic binding protein, through the cited periplasmic domain of LuxQ.
