Schematic drawing of T4SSs showing known and/or predicted localization
of A. 17 T4SS proteins important for DNA secretion by N.
gonorrhoeae, B. homologous proteins from the F-plasmid
T4SSs C. homologous proteins from the P-type T4SSs. Previously
identified interactions are shown by lines: A. The TraV/TraK
interaction described in Ramsey et al.
2014
B. Interactions described in Harris
et al. 2001 (Harris et al.,
2001) and Harris and Silverman
2004 (Harris and Silverman,
2004). C. Interactions from Das et al. 1997 and Das and Xie 2000. OM, outer membrane, IM, inner membrane, PG,
peptidoglycan. Proteins shared between the three systems are shown in red/violet
colors while F-type specific proteins are shown in green. Proteins specific to
N. gonorrhoeae are shown in yellow while VirB11 found only
in the P-type system is shown in blue.
