ORF information
ORF ID TF00290 (frame 1) Gene ID BRA0066
Position and sequences 62913...65408(831 aa) Gene Name/synonym virB4 /virB4s
Organism Brucella suis 1330 Cluster 68 genes
Product Type IV secretion system protein VirB4 homolog
1stcategory P-T4SS 2ndcategory VirB4/TrbE/CagE Family
3rdcategory Effector translocator
Function The VirB T4SS could be required for the establishment of the replication niche in the host. VirB4-VirB8 and VirB10-VirB8 interactions are required for B.suis biological activity.
Miscellaneus VirB system is specifically induced within macrophages by phagosome acidification. Induced at 37 degrees Celsius in minimal medium, suggesting that nutritional stress is a regulating signal.
