Domain architectures of effectors deployed by endosymbiotic/parasitic bacteria illustrating certain common functional strategies. Proteins are labeled by their gene names, species abbreviations and genbank index (GI) numbers separated by underscores. Non-standard domain names and expansion of species abbreviations are given in the key below the figure. Additionally, Amoebophilus prodomain 1 (APD1) and Amoebophilus prodomain 2 (APD2) are Amoebophilus-specific N-terminal domains that are present immediately downstream of a signal peptide and a lipobox. These domains are likely to help in the specific localization and/or clustering of effectors from this organism.
