periplasmic binding domain of basic membrane lipoprotein, PnrA, in Treponema pallidum and its homologs from other bacteria and Archaea; Periplasmic binding domain of basic membrane lipoprotein, PnrA, in Treponema pallidum and its homologs from other bacteria and Archaea. The PnrA lipoprotein, also known as Tp0319 or TmpC, represents a novel family of bacterial purine nucleoside receptor encoded within an ATP-binding cassette (ABC) transport system (pnrABCDE). It shows a striking structural similarity to another basic membrane lipoprotein Med which regulates the competence transcription factor gene, comK, in Bacillus subtilis. The members of PnrA-like subgroup are likely to have similar nucleoside-binding functions and a similar type 1 periplasmic sugar-binding protein-like fold.

ABC transporter substrate-binding protein PnrA-like; Proteins containing this domain were originally annotated as basic membrane lipoproteins. However, several proteins containing this domain were later predicted as ABC transporter substrate-binding proteins, such as PnrA (also known as TmpC or TP0319) and RfuA (also known as Tpn38 or TP0298) from Treponema pallidum. PnrA transports purine nucleosides, while RfuA transports riboflavin. Proteins containing this domain also include Med from Bacillus subtilis. Med was annotated as a transcriptional activator protein that regulates comK. This domain can also found at the N terminus of glutamate receptor-like proteins from Dictyostelium (slime mold).

periplasmic binding domain of the basic membrane lipoprotein Med in Bacillus and its close homologs from other bacteria and Archaea; Periplasmic binding domain of the basic membrane lipoprotein Med in Bacillus and its close homologs from other bacteria and Archaea. Med, a cell-surface localized protein, which regulates the competence transcription factor gene comK in Bacillus subtilis, lacks the DNA binding domain when compared with structures of transcription regulators from the LacI family. Nevertheless, Med has significant overall sequence homology to various periplasmic substrate-binding proteins. Moreover, the structure of Med shows a striking similarity to PnrA, a periplasmic nucleoside binding protein of an ATP-binding cassette transport system. Members of this group contain the type 1 periplasmic sugar-binding protein-like fold.

Type 1 periplasmic binding fold superfamily; Type 1 periplasmic binding fold superfamily. This model and hierarchy represent the ligand binding domains of the LacI family of transcriptional regulators, periplasmic binding proteins of the ABC-type transport systems, the family C G-protein couples receptors (GPCRs), membrane bound guanylyl cyclases including the family of natriuretic peptide receptors (NPRs), and the N-terminal leucine-isoleucine-valine binding protein (LIVBP)-like domains of the ionotropic glutamate receptors (iGluRs). In LacI-like transcriptional regulator and the bacterial periplasmic binding proteins, the ligands are monosaccharides, including lactose, ribose, fructose, xylose, arabinose, galactose/glucose and other sugars, with a few exceptions. Periplasmic sugar binding proteins are one of the components of ABC transporters and are involved in the active transport of water-soluble ligands. The LacI family of proteins consists of transcriptional regulators related to the lac repressor. In this case, the sugar binding domain binds a sugar which changes the DNA binding activity of the repressor domain. The periplasmic binding proteins are the primary receptors for chemotaxis and transport of many sugar based solutes. The core structures of periplasmic binding proteins are classified into two types, and they differ in number and order of beta strands: type 1 has six beta strands while type 2 has five beta strands per sub-domain. These two structural folds are thought to be distantly related via a common ancestor. Notably, while the N-terminal LIVBP-like domain of iGluRs belongs to the type 1 periplasmic-binding fold protein superfamily, the glutamate-binding domain of the iGluR is structurally similar to the type 2 periplasmic-binding fold.
