Abstract

Péptido con actividad inhibidora de Quorum Sensing, polinucleótido que codifica dicho péptido y sus aplicaciones. Se describe la donación, secuenciación y caracterización del gen responsable de la actividad Quorum Quenching (QQ) frente a señales de Quorum Sensing (QS) de la cepa Tenacibacuium sp. 20J (CECT7426). Dicho gen codifica un péptido que presenta al menos actividad lactonasa con un porcentaje de identidad inferior al 38% con las lactonasas descritas hasta el momento para otras especies, así como las secuencias de los genes homólogos presentes en otras especies del género Tenacibacuium. Dicho péptido muestra un amplio espectro de actividad degradando N-acil-homoserin lactonas (AHLs) de 4-14 átomos de carbono en su cadena lateral, opcionalmente sustituidas, es activo a pH comprendido entre 3 y 9, resistente a proteinasa K y quimiotripsina y no interactúa con antibióticos 13β-lactámicos.
