Organism Bartonella quintana Toulouse Cluster 68 genes
Product Type IV secretion system protein VirB4 homolog
1stcategory P-T4SS 2ndcategory VirB4/TrbE/CagE Family
3rdcategory Effector translocator
Function Component of the type IV secretion system virB/virD4 which could be a major virulence determinant for subversion of human endothelial cell (HEC) function. Together with virB11, may be implicated in providing the energy, via hydrolysis of ATP, for the assembly of secretion system and substrate transport.
