Abstract:
:The FemAB-like factors Lif and Epr confer resistance to glycylglycine endopeptidases lysostaphin and Ale-1, respectively, by incorporating serine residues into the staphylococcal peptidoglycan interpeptide bridges specifically at positions 3 and 5. This required the presence of FemA and/or FemB, in contrast to earlier postulations.

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. ...
