ORF ID | TF02007 (frame 1) |
Gene ID | A1C_02060 |
Position and sequences | 385158...385634(158 aa) |
Gene Name/synonym |
virB9-2
- |
Organism | Rickettsia akari Hartford |
Cluster |
5 genes |
Product | Type IV secretion system protein VirB9-2 homolog |
1stcategory | P-T4SS |
2ndcategory | VirB9/TrbG Family |
3rdcategory | Probable effector translocator |
Function | VirB9 is a component of the core T4SS complex.Functions in DNA uptake and release and/or conjugation cannot be ruled out. |
Miscellaneus | Rickettsia genomes contain two VirB9 genes (virB9a and virB9b) encoded immediately downstream of the two VirB8 genes. virB9a is more conserved across Rickettsia genomes than virB9b at the nucleotide and amino acid levels. Interestingly, Rickettsia VirB9a proteins contain the conserved Cys residue implicated in disulphide bridge formation with VirB7, despite a lack of conservation of the Cys residue in most others VirB9 proteins.
