1
Consensus annotation. Grouped by function: substrate presentation (VirD4), translocation energetics (VirB4, VirB11), mating channel (VirB6, VirB8-VirB10), attachment (VirB3).
2
Length (aa) of R. typhi query sequence.
3
Number of blastp subjects yielding significant alignments (maximum hits set to 500).
4
Distribution of subjects across five classes of proteobacteria.
5
Non-proteobacterial subjects, with number of plasmid encoded proteins in parentheses. Note: plasmid encoded Vir and Vir-like proteins were not assigned to a taxonomic class, hence some may be from plasmids found in proteobacteria.
