Figure 3From: Genome reannotation of Escherichia coli CFT073 with new insights into virulenceStructural domains of c0139's product in the reannotation and autotransporter virulence factor antigen 43. The domain in blue has the ability to form a β-barrel, also termed autotransporter domain, and is a key component in self-exportation; the domain in green is the passenger domain, which varies widely with different ATs; the segment in red is signal peptide, which guides the whole protein during the translocation; and the dashed line indicates the cleavage site in which protease cuts AT and releases the passenger segment.Back to article page
