PulE-GspE family; PulE and General secretory pathway protein GspE are ATPases of the type II secretory pathway, the main terminal branch of the general secretory pathway (GSP). PulE is a cytoplasmic protein of the GSP, which contains an ATP binding site and a tetracysteine motif. This subgroup also includes PilB, a type IV pilus assembly ATPase, DotB, an ATPase of the type IVb secretion system, also known as the dot/icm system, Escherichia coli IncI plasmid-encoded conjugative transfer ATPase TraJ, and HofB.

Type II/IV secretion system protein; This family contains components of both the Type II protein secretion system (T2SS), including Type 4 pilus (T4P), and Type IV protein secretion system (T4SS) from Gram-negative bacteria. 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. 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.

pilus retraction protein PilT; This model represents the PilT subfamily of proteins related to GspE, a protein involved in type II secretion (also called the General Secretion Pathway). PilT is an apparent cytosolic ATPase associated with type IV pilus systems. It is not required for pilin biogenesis, but is required for twitching motility and social gliding behaviors, shown in some species, powered by pilus retraction. Members of this family may be found in some species that type IV pili but have related structures for DNA uptake and natural transformation.

Type IV secretory pathway component VirB11-like; Type IV secretory pathway component VirB11, and related ATPases. The homohexamer, VirB11 is one of eleven Vir (virulence) proteins, which are required for T-pilus biogenesis and virulence in the transfer of T-DNA from the bacterial Ti (tumor-inducing)-plasmid into plant cells. The pilus is a fibrous cell surface organelle, which mediates adhesion between bacteria during conjugative transfer or between bacteria and host eukaryotic cells during infection. VirB11-related ATPases include Sulfolobus acidocaldarius FlaI, which plays key roles in archaellum (archaeal flagellum) assembly and motility functions, and the pilus assembly proteins CpaF/TadA and TrbB. This alignment contains the C-terminal domain, which is the ATPase.
