Figure 6. Amino acid sequence analysis of identified VirB substrates.
(A) Schematic representation of BPE proteins translocated across B. abortus VirB system. The number of amino acids is indicated on the right. cNMP: cyclic Nucleotide Mono-Phosphate; Vertical bars represent transmembrane domains; APO: apolipoprotein; SP: Sec Signal Peptide; (B) Percentage of identity between B. abortus 2308 VirB translocated BPEs and their orthologs in representative Brucella species and the phylogenetically related species O. anthropi and O. intermedium. (C) B. abortus VirB translocated substrates C-terminal 30 amino acids. Positively charged amino acids are shaded.
