Notes

A consensus has been reached for renaming the genes that encode components of the outer membrane β-barrel assembly machine, (formerly known as the YaeT complex of E. coli or the Omp85 complex of N. meningitidis). The new designation for this multi-component structure is the Bam complex (for beta-barrel assembly machine).

The Bam complex in E. coli consists of BamA (YaeT), BamB (YfgL), BamC (NlpB), BamD (YfiO), and BamE (SmpA). Letters have been assigned on the basis of molecular weight, from highest to lowest [2].

Notes

NlpB is not essential and demonstrates very subtle outer membrane defects. nlpB- cells affect the stability of the multiprotein YaeT (Bam) complex in vitro [7],[8].
