Fig. 5

Presence of homologs of gliding motility and type 9 secretion proteins in the predicted proteomes. Presence of homologs is indicated by light blue squares and absence by white squares. Strains sequenced in the framework of this study are indicated in bold. Each species was annotated based on its taxonomy (Groups) and motility as reported in literature. Protein names in bold are considered essential or important for F. johnsoniae gliding. The rest of the proteins are either non-essential or their role in F. johnsoniae gliding has not been determined [24, 32]. Other, gliding motility mechanism other than T9SS-based; NA, no information available (see also Additional file 3)
