CommentType IV secretion systems are found in Gram-negative pathogens. They export proteins, DNA, or complexes in different systems and are related to plasmid conjugation systems. This model represents related ATPases that include VirB4 in Agrobacterium tumefaciens (DNA export) CagE in Helicobacter pylori (protein export) and plasmid TraB (conjugation).
