Type 2 periplasmic binding fold superfamily; This evolutionary model and hierarchy represent the ligand-binding domains found in solute binding proteins that serve as initial receptors in the transport, signal transduction and channel gating. The PBP2 proteins share the same architecture as periplasmic binding proteins type 1 (PBP1), but have a different topology. They are typically comprised of two globular subdomains connected by a flexible hinge and bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap. The origin of PBP module can be traced across the distant phyla, including eukaryotes, archebacteria, and prokaryotes. The majority of PBP2 proteins are involved in the uptake of a variety of soluble substrates such as phosphate, sulfate, polysaccharides, lysine/arginine/ornithine, and histidine. After binding their specific ligand with high affinity, they can interact with a cognate membrane transport complex comprised of two integral membrane domains and two cytoplasmically located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis. Besides transport proteins, the family includes ionotropic glutamate receptors and unorthodox sensor proteins involved in signal transduction. The substrate binding domain of the LysR transcriptional regulators and the oligopeptide-like transport systems also contain the type 2 periplasmic binding fold and thus they are significantly homologous to that of the PBP2; however, these two families are grouped into a separate hierarchy of the PBP2 superfamily due to the large number of protein sequences.

Substrate binding domain of ABC-type nitrate/sulfonate/bicarbonate transporters, a member of the type 2 periplasmic binding fold superfamily; This family represents the periplasmic binding proteins involved in nitrate, alkanesulfonate, and bicarbonate transport. These domains are found in eubacterial perisplamic-binding proteins that serve as initial receptors in the ABC transport of bicarbonate, nitrate, taurine, or a wide range of aliphatic sulfonates. Other closest homologs involved in thiamine (vitamin B1) biosynthetic pathway and desulfurization (DszB) are also included in this family. After binding their ligand with high affinity, they interact with a cognate membrane transport complex comprised of two integral membrane domains and two cytoplasmically located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis. These binding proteins belong to the PBP2 superfamily of periplasmic binding proteins that differ in size and ligand specificity, but have similar tertiary structures consisting of two globular subdomains connected by a flexible hinge. They have been shown to bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap. Pssm-ID: 270229 [Multi-domain] Cd Length: 212 Bit Score: 40.35 E-value: 4.54e-04

ABC transporter, substrate-binding protein, aliphatic sulfonates family; Members of this family are substrate-binding periplasmic proteins of ABC transporters. This subfamily includes SsuA, a member of a transporter operon needed to obtain sulfur from aliphatic sulfonates. Related proteins outside the scope of this model include taurine (NH2-CH2-CH2-S03H) binding proteins, the probable sulfate ester binding protein AtsR, and the probable aromatic sulfonate binding protein AsfC. All these families make sulfur available when Cys and sulfate levels are low. Please note that phylogenetic analysis by neighbor-joining suggests that a number of sequences belonging to this family have been excluded because of scoring lower than taurine-binding proteins.
