SecReT6 ID	794
Strain	Vibrio alginolyticus EPJS
Replicon	chromosome [Browse all T6SS(s) in this replicon]
Accession	FJ790777
Location	1..31102
Comment	In-frame deletion of VEPGS_0008 resulted in obvious biofilm reduction and the complemented strain restored to the level of the wild-type strain. Besides, in-frame deletion of dotU1, VEPGS_0008 and ppkA2 abolished the swarming ability.
Function	N/A
T6SS Type	Type i; subtype i5
