Protein
Beta-barrel assembly-enhancing protease
Organism
Escherichia coli (strain K12)
Function
Functions as both a chaperone and a metalloprotease. Maintains the integrity of the outer membrane by promoting either the assembly or the elimination of outer membrane proteins, depending on their folding state. Promotes disulfide rearrangement of LptD during its biogenesis, and proteolytic degradation of LptD and BamA when their proper assembly is compromised. May facilitate membrane attachment of LoiP under unfavorable conditions.
Similarity
Belongs to the peptidase M48 family. BepA subfamily.
