The Escherichia coli phn operon encodes 14 genes involved in binding, uptake and metabolism of phosphonate, and is activated under phophophate-limiting conditions. PhnD belongs 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. The PBP2 have been shown to bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap.

phosphate/phosphite/phosphonate ABC transporter, periplasmic binding protein; Phosphonates are a varied class of phosphorus-containing organic compound in which a direct C-P bond is found, rather than a C-O-P linkage of the phosphorus through an oxygen atom. They may be toxic but also may be used as sources of phosphorus and energy by various bacteria. Phosphonate utilization systems typically are encoded in 14 or more genes, including a three gene ABC transporter. This family includes the periplasmic binding protein component of ABC transporters for phosphonates as well as other, related binding components for closely related substances such as phosphate and phosphite. A number of members of this family are found in genomic contexts with components of selenium metabolic processes suggestive of a role in selenate or other selenium-compound transport. A subset of this model in which nearly all members exhibit genomic context with elements of phosphonate metabolism, particularly the C-P lyase system (GenProp0232) has been built (TIGR03431) as an equivalog. Nevertheless, there are members of this subfamily (TIGR01098) which show up sporadically on a phylogenetic tree that also show phosphonate context and are most likely competent to transport phosphonates.

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.
