ORF information
ORF ID TF00314 (frame 1) Gene ID SMa1315
Position and sequences 717133...719511(792 aa) Gene Name/synonym avhB4 -
Organism Sinorhizobium meliloti 1021 Cluster 68 genes
Product Type IV secretion system protein VirB4 homolog
1stcategory P-T4SS 2ndcategory VirB4/TrbE/CagE Family
3rdcategory Conjugation
Function Component of the T4SS virB/D4 homolog that is required for conjugal transfer of the pSymA. However T4SS virB/D4 homolog is not required for the intracellular survival of the bacteria, thus it appears to be dispensable for plant symbiosis. VirB11 probably binds ATP.
