1.B.12.4.2
Autoexporter of temperature-sensitive hemagglutinin, a hemoglobin binding protease, Tsh/Hbp (1377 aas) (Jong and Luirink, 2008; Peterson et al., 2006). The pore of the Hbp TD is largely obstructed, but a variant that lacked one amino acid residue from the N-terminus showed the opening and closing of a channel comparable to what was reported for the TD of NalP. Hbp is processed by an autocatalytic intramolecular mechanism resulting in the stable docking of the α-helical plug in the barrel.
