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 [3].

edit table |
<protect></protect>
Notes
yaeT6 carries a 6-bp in-frame insertion (agaaac) between codons 218 and 219 of yaeT. At the protein level, the suppressor mutation results in an in-frame insertion of Gln–Lys after amino acid 218 of YaeT. The yaeT6 mutation was isolated as a suppressor of the imp4213 allele of lptD.[5]
The mutant allele bamA66 is a deletion of the R64 codon of bamA. The mutant protein is referred to as BamA(delR64). The bamA66 mutation was isolated as a suppressor that conferred increased resistance to bacitracin of a strain carrying the imp208 allele of lptD. In an lptD+ background, bamA66 displays a slight sensitivity to vancomycin and rifampin and causes a moderate reduction (20–30%) in OMP levels, but is synthetically lethal with the depletion of BamB, conditionally lethal in the absence of DegP or SurA; i.e. no growth at or above 37°C and 40°C respectively.[6]
