Neisseria meningitidis possède un PTS incomplet. Constitué des composants générales EI et HPr et de deux EIIAs (EIIANtr et EIIAMan), ce système ne permet pas le transport des sucres chez cette bactérie. Cependant, nous avons confirmé que la cascade de phosphorylation (EI HPr EIIANtr) est fonctionnelle et que HPr est aussi phosphorylée sur sa Ser-46 par une HprK/P.Dans l’objectif d’étudier l’effet de HPr sur la virulence de N. meningitidis, nous avons construit un mutant ΔptsH chez N. meningitidis 2C4-3. Le mutant ΔptsH a montré une faible survie chez la souris, une faible production de la capsule, une meilleure adhérence aux cellules épithéliales et un niveau élevé de cellules apoptotiques, par rapport à la souche sauvage. HPr semble interv...
