created two fusion proteins, with the intact b-domain
only and with the full autotransporter. While the full autotransporter
was efficiently secreted into the culture medium,
fusion proteins lacking the passenger domain showed no activity.
Thus, fusion to an entire autotransporter appears to be
necessary for efficient secretion in this case. When parts of
passenger domain are considered to be essential, it usually has
to resort a trial and error approach to identify the insertion
point for the target protein within the passenger domain. For
example, Jong et al. screened five passenger domains (Hbp)
fused to the tuberculosis vaccine target ESAT6, along with an
intact b-domain
