Aromatic solutes transporter of Bug (Bordetella uptake gene) protein family; contains the type 2 periplasmic binding fold; Bug27 binds non-carboxylated solute nicotinamide, in contrast to BugD (aspartic acid transporter) and BugE (glutamate transporter) which both bind aliphatic carboxylated ligands. The Bug (Bordetella uptake gene) protein family is a large family of periplasmic solute-binding (PBP) receptors present in a number of bacterial species, but mainly in proteobacteria. Bug proteins are the PBP components of the tripartite carboxylate transporters (TTT). Their expansive expansion in proteobacteria indicates a large functional diversity.

Tripartite tricarboxylate transporter family receptor; These probable extra-cytoplasmic solute receptors are strongly overrepresented in several beta-proteobacteria. This family, formerly known as Bug - Bordetella uptake gene (bug) product - is a family of bacterial tripartite tricarboxylate receptors of the extracytoplasmic solute binding receptor-dependent transporter group of families, distinct from the ABC and TRAP-T families. The TctABC system has been characterized in S. typhimurium, and TctC is the extracytoplasmic tricarboxylate-binding receptor which binds the transporters TctA and TctB, two integral membrane proteins. Complete three-component systems are found only in bacteria.

Bug (Bordetella uptake gene) protein family of periplasmic solute-binding receptors; contains the type 2 periplasmic binding fold; The Bug (Bordetella uptake gene) protein family is a large family of periplasmic solute-binding (PBP) proteins present in a number of bacterial species, but mainly in proteobacteria. In eubacteria, at least three families of periplasmic binding-protein dependent transporters are known: the ATP-binding cassette (ABC) transporters, the tripartite ATP-independent periplasmic transporters, and the tripartite tricarboxylate transporters (TTT). Bug proteins are the PBP components of the TTT. Their expansive expansion in proteobacteria indicates a large functional diversity. The best studied examples are Bordetella pertussis BugD, which is an aspartic acid transporter, and BugE, which is glutamate transporter.

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.
