Un procedimiento eficaz para evaluar la propensión de oligomerización dominios transmembrana de un solo paso (TTM) se describe. Proteínas quiméricas que consiste en la DTM fundido a toxR se expresan en una cepa de E. coli reportero. TMD inducida por oligomerización causas dimerización de toxR, activación de la transcripción y la producción de la proteína reportera,-galactosidasa.
