RHS repeat-associated core domain; This model represents a conserved unique core sequence shared by large numbers of proteins. It is occasional in the Archaea Methanosarcina barkeri) but common in bacteria and eukaryotes. Most fall into two large classes. One class consists of long proteins in which two classes of repeats are abundant: an FG-GAP repeat (pfam01839) class, and an RHS repeat (pfam05593) or YD repeat (TIGR01643). This class includes secreted bacterial insecticidal toxins and intercellular signalling proteins such as the teneurins in animals. The other class consists of uncharacterized proteins shorter than 400 amino acids, where this core domain of about 75 amino acids tends to occur in the N-terminal half. Over twenty such proteins are found in Pseudomonas putida alone; little sequence similarity or repeat structure is found among these proteins outside the region modeled by this domain.

proline-alanine-alanine-arginine (PAAR) domain; This domain is found in the PAAR (proline-alanine-alanine-arginine) repeat family, where it forms a sharp conical extension on the VgrG spike, a trimeric protein complex of the bacterial type VI secretion system (T6SS). The T6SS is responsible for translocation of a wide variety of toxic effector molecules, allowing predatory cells to kill prokaryotic as well as eukaryotic prey cells. The pointed tip of the PAAR domain is stabilized by a zinc atom positioned close to the cone's vertex and is likely to be important for its integrity during penetration of the target cell envelope. VgrG proteins are orthologous to the central baseplate spikes of bacteriophages with contractile tails, and genes encoding proteins with PAAR motifs have been frequently found immediately downstream from vgrG-like genes. It has been shown that PAAR proteins are essential for T6SS-mediated secretion and target cell killing by Vibrio cholerae (encodes two PAAR proteins) and Acinetobacter baylyi (encodes three PAAR proteins); inactivation of all these PAAR genes results in inactivation of Hcp secretion as well as T6SS-dependent killing of E. coli.

proline-alanine-alanine-arginine (PAAR) domain with C-terminal extension; This domain is found in the PAAR (proline-alanine-alanine-arginine) repeat family of mostly gamma-proteobacteria, and forms a sharp conical extension on the VgrG spike, a trimeric protein complex of the bacterial type VI secretion system (T6SS). Some members contains C-terminal domain extensions corresponding to Rearrangement hotspot (Rhs) protein repeats and conserved Rhs repeat-associated unique core sequences as well as uncharacterized domains.
