Fig. 2From: A plasmid-encoded papB paralogue modulates autoaggregation of Escherichia coli transconjugantsa Alignment of the pMB2-encoded PefB-like protein with a selection of known PapB homologs. PapB residues known to be required for fim-switching activity of PapB are indicated in bold. b Unrooted maximum likelihood tree of PapB paralogues including the PefB-like protein in this study (boxed), based on a Jones–Taylor–Thornton (JTT) substitution model. Bootstrap values from 1000 tree replicates generated using MEGA6 are given at branch pointsBack to article page
