Genetic Composition and Organization of Phage-Tail-Like Systems
(A) Three previously reported eCIS loci and their consensus composition. The 11 consensus components shared by all three loci are summarized below. Experimentally verified essential genes in the MAC are indicated with stars.
(B) The T6SSiv in Amoebophilus asiaticus, which is closely related to eCIS (Böck et al., 2017).
(C) Representatives of classical T6SS and R-type bacteriocin loci. Homologous components carrying the same protein domain as that of eCIS are denoted with the same color. Singleton genes are represented in gray.
(D) Venn diagram of the homologs to the 11 consensus components of eCIS in classical T6SS and R-type bacteriocin. The two key components (afp1/5 and afp11) employed for eCIS screening are indicated.
