Tbp2 fragments of the transferrine receptor of neisseria meningitidis

摘要

Polypeptide having a sequence of amino acids derived from that of the Tbp2 subunit of the transferrine receptor of a Neisseria meningitidis strain of the IM2169 or IM2394 type, the first, second and third domains being defined by maximum homologous alignment on the Tbp2 subunit sequence of the respective IM2169 or IM2394 reference strain, especially by total or partial deletion of at least one domain of said Tbp2 subunit of the IM2169 or IM2394 type provided the first and second domains are not fully deleted at the same time.
