Aspartate aminotransferase family. This family belongs to pyridoxal phosphate (PLP)-dependent aspartate aminotransferase superfamily (fold I). Pyridoxal phosphate combines with an alpha-amino acid to form a compound called a Schiff base or aldimine intermediate, which depending on the reaction, is the substrate in four kinds of reactions (1) transamination (movement of amino groups), (2) racemization (redistribution of enantiomers), (3) decarboxylation (removing COOH groups), and (4) various side-chain reactions depending on the enzyme involved. Pyridoxal phosphate (PLP) dependent enzymes were previously classified into alpha, beta and gamma classes, based on the chemical characteristics (carbon atom involved) of the reaction they catalyzed. The availability of several structures allowed a comprehensive analysis of the evolutionary classification of PLP dependent enzymes, and it was found that the functional classification did not always agree with the evolutionary history of these enzymes. The major groups in this CD corresponds to Aspartate aminotransferase a, b and c, Tyrosine, Alanine, Aromatic-amino-acid, Glutamine phenylpyruvate, 1-Aminocyclopropane-1-carboxylate synthase, Histidinol-phosphate, gene products of malY and cobC, Valine-pyruvate aminotransferase and Rhizopine catabolism regulatory protein.

Bacterial regulatory proteins, gntR family; This family of regulatory proteins consists of the N-terminal HTH region of GntR-like bacterial transcription factors. At the C-terminus there is usually an effector-binding/oligomerization domain. The GntR-like proteins include the following sub-families: MocR, YtrR, FadR, AraR, HutC and PlmA, DevA, DasR. Many of these proteins have been shown experimentally to be autoregulatory, enabling the prediction of operator sites and the discovery of cis/trans relationships. The DasR regulator has been shown to be a global regulator of primary metabolism and development in Streptomyces coelicolor.

trehalose operon repressor, B. subtilis-type; This family consists of repressors of the GntR family typically associated with trehalose utilization operons. Trehalose is imported as trehalose-6-phosphate and then hydrolyzed by alpha,alpha-phosphotrehalase to glucose and glucose-6-P. This family includes repressors mostly from Gram-positive lineages and does not include the TreR from E. coli. [Regulatory functions, DNA interactions]

Winged helix-turn-helix (WHTH) DNA-binding domain of the GntR family of transcriptional regulators; This CD represents the winged HTH DNA-binding domain of the GntR (named after the gluconate operon repressor in Bacillus subtilis) family of bacterial transcriptional regulators and their putative homologs found in eukaryota and archaea. The GntR family has over 6000 members distributed among almost all bacterial species, which is comprised of FadR, HutC, MocR, YtrA, AraR, PlmA, and other subfamilies for the regulation of the most varied biological process. The monomeric proteins of the GntR family are characterized by two function domains: a small highly conserved winged helix-turn-helix prokaryotic DNA binding domain in the N-terminus, and a very diverse regulatory ligand-binding domain in the C-terminus for effector-binding/oligomerization, which provides the basis for the subfamily classifications. Binding of the effector to GntR-like transcriptional regulators is presumed to result in a conformational change that regulates the DNA-binding affinity of the repressor. The GntR-like proteins bind as dimers, where each monomer recognizes a half-site of 2-fold symmetric DNA sequences.

Aspartate amino-transferase; These proteins catalyze the reversible transfer of an amino group from the amino acid substrate to an acceptor alpha-keto acid. They require pyridoxal 5'-phosphate (PLP) as a cofactor to catalyze this reaction. Trans-amination reactions are of central importance in amino acid metabolism and in links to carbohydrate and fat metabolism. This class of amino-transferases acts as dimers in a head-to-tail configuration. It has been demonstrated that these proteins are aspartate amino-transferases from Bacteria (Jansen, R.S. et al. Nat Commun 11, 1960 (2020)).
