Swiss:P07169 VirB11 ATPase is a subunit of the Agrobacterium tumefaciens transfer DNA (T-DNA) transfer system, a type IV secretion pathway required for delivery of T-DNA and effector proteins to plant cells during infection [1]. The cytoplasmic T2S E ATPase is a Zn-containing protein thought to provide the mechanical force for the secretion process. T2S-E contains Walker A and B motifs, that are essential for secretion and ATPase activity. ATPase PulE and XcpR from Klebsiella oxytoca and Pseudomonas aeruginosa respectively are required for protein secretion via the T2SS. ATPase PilB is required for T4P extension [2]. The type II protein secretion system (T2SS) is a sophisticated multi-protein machinery containing 12-15 different proteins [3]. Historically, this system was described as the main terminal branch (MTB) of the general secretory pathway (GSP), but this nomenclature is now on obsolete [4].
