Phylogeny and structure of the outer-membrane protein PilQ. (A) Phylogeny and domain architecture of the outer-membrane channel protein, PilQ, in the type IV pili system. The phylogeny was inferred with the maximum likelihood method with 100 bootstraps. Only bootstrap support values ≥70 are shown. (B) The partial structure of the PilQ monomer in Myxococcus xanthus (pdb ID: 3JC9) (Chang et al. 2016) is shown beside the predicted structure of the PilQ monomer in Gemmata obscuriglobus and Gimesia maris.
