The essential ß-barrel assembly machinery complex components BamD and BamA are required for autotransporter biogenesis.

ABSTRACT

Autotransporter biogenesis is dependent upon BamA, a central component of the ß-barrel assembly machinery (BAM) complex. In this report, we detail the role of the other BAM components (BamB-E). We identify the importance of BamD in autotransporter biogenesis and show that BamB, BamC, and BamE are not required.
