Comparison of gene clusters that encode type VII secretion system (T7SS also ESX) in C. ulceribovis DSM 45146T and variants that are present in other mycolic acid-containing taxa of the Corynebacterineae. Six genes encoding for six proteins are generally present in all the examined species. These proteins are: two members of the ESAT-6 family (Esat-6 and CFP-10); a member of the FtsK/SpoIIIE family (EccCab); a subtilisin-like protease (MycP); an integral membrane protein with 10–11 transmembrane domains (EccD); a member of another membrane-protein family (EccB); In addition, two proteins the PE (proline-glutamine) and PPE (proline-proline-glutamine) encoded by two genes are shared by some, but not all T7SS systems. Orthologs are shown by matching colors
