Receptor for glutamate. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. The postsynaptic actions of Glu are mediated by a variety of receptors that are named according to their selective agonists. Drosophila melanogaster (taxid: 7227)
Non-NMDA (N-methyl-D-aspartate) ionotropic glutamate receptor. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. The postsynaptic actions of glutamate are mediated by a variety of receptors that are named according to their selective agonists. May contribute to a sensory discrimination between mechanical and chemical stimuli.
Receptor for glutamate that functions as ligand-gated ion channel in the central nervous system and plays an important role in excitatory synaptic transmission. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. Binding of the excitatory neurotransmitter L-glutamate induces a conformation change, leading to the opening of the cation channel, and thereby converts the chemical signal to an electrical impulse. The receptor then desensitizes rapidly and enters a transient inactive state, characterized by the presence of bound agonist. In the presence of CACNG4 or CACNG7 or CACNG8, shows resensitization which is characterized by a delayed accumulation of current flux upon continued application of glutamate.

>PF00497 SBP_bac_3: Bacterial extracellular solute-binding proteins, family 3; InterPro: IPR001638 Bacterial high affinity transport systems are involved in active transport of solutes across the cytoplasmic membrane
The protein components of these traffic systems include one or two transmembrane protein components, one or two membrane-associated ATP-binding proteins (ABC transporters; see IPR003439 from INTERPRO) and a high affinity periplasmic solute-binding protein. The latter are thought to bind the substrate in the vicinity of the inner membrane, and to transfer it to a complex of inner membrane proteins for concentration into the cytoplasm. In Gram-positive bacteria which are surrounded by a single membrane and have therefore no periplasmic region, the equivalent proteins are bound to the membrane via an N-terminal lipid anchor. These homologue proteins do not play an integral role in the transport process per se, but probably serve as receptors to trigger or initiate translocation of the solute throught the membrane by binding to external sites of the integral membrane proteins of the efflux system. In addition, at least some solute-binding proteins function in the initiation of sensory transduction pathways. On the basis of sequence similarities, the vast majority of these solute-binding proteins can be grouped [] into eight families or clusters, which generally correlate with the nature of the solute bound. Family 3 groups together specific amino acids and opine-binding periplasmic proteins and a periplasmic homologue with catalytic activity.; GO: 0005215 transporter activity, 0006810 transport, 0030288 outer membrane-bounded periplasmic space; PDB: 3N26_A 3QAX_A 3I6V_A 2VHA_B 2IA4_B 2Q89_A 2Q88_A 2YJP_C 1II5_A 1IIW_A ....
>TIGR03871 ABC_peri_MoxJ_2 quinoprotein dehydrogenase-associated probable ABC transporter substrate-binding protein
This protein family, a sister family to TIGR03870, is found more broadly. It occurs a range of PQQ-biosynthesizing species, not just in known methanotrophs. Interpretation of evidence by homology and by direct experimental work suggest two different roles. By homology, this family appears to be the periplasmic substrate-binding protein of an ABC transport family. However, mutational studies and direct characterization for some sequences related to this family suggests this family may act as a maturation chaperone or additional subunit of a methanol dehydrogenase-like enzyme.
>PRK09959 hybrid sensory histidine kinase in two-component regulatory system with EvgA; Provisional
This predicted periplasmic protein, called MoxJ or MxaJ, is required for methanol oxidation in Methylobacterium extorquens. Two differing lines of evidence suggest two different roles. Forming one view, homology suggests it is the substrate-binding protein of an ABC transporter associated with methanol oxidation. The gene, furthermore, is found regular in genomes with, and only two or three genes away from, a corresponding permease and ATP-binding cassette gene pair. The other view is that this protein is an accessory factor or additional subunit of methanol dehydrogenase itself. Mutational studies show a dependence on this protein for expression of the PQQ-dependent, two-subunit methanol dehydrogenase (MxaF and MxaI) in Methylobacterium extorquens, as if it is a chaperone for enzyme assembly or a third subunit. A homologous N-terminal sequence was found in Paracoccus denitrificans as a 32Kd third subunit. This protein may, in
A subset of this model in which nearly all members exhibit genomic context with elements of phosphonate metabolism, particularly the C-P lyase system 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.
>PRK09959 hybrid sensory histidine kinase in two-component regulatory system with EvgA; Provisional
Members of this family are the extracellular solute-binding proteins of ABC transporters that closely resemble amino acid transporters. The member from Sinorhizobium meliloti is involved in ectoine uptake, both for osmoprotection and for catabolism. All other members of the seed alignment are found associated with ectoine catabolic genes.
>cd00134 PBPb Bacterial periplasmic transport systems use membrane-bound complexes and substrate-bound, membrane-associated, periplasmic binding proteins (PBPs) to transport a wide variety of substrates, such as, amino acids, peptides, sugars, vitamins and inorganic ions
PBPs have two cell-membrane translocation functions: bind substrate, and interact with the membrane bound complex. A diverse group of periplasmic transport receptors for lysine/arginine/ornithine (LAO), glutamine, histidine, sulfate, phosphate, molybdate, and methanol are included in the PBPb CD.
Members of this family are found in several Proteobacteria, including Pseudomonas putida KT2440, Bdellovibrio bacteriovorus HD100 (three members), Aeromonas hydrophila, and Chromobacterium violaceum ATCC 12472. The function is unknown.
>PF00405 Transferrin: Transferrin; InterPro: IPR001156 Transferrins are eukaryotic iron-binding glycoproteins that control the level of free iron in biological fluids []
The proteins have arisen by duplication of a domain, each duplicated domain binding one iron atom. Members of the family include blood serotransferrin (siderophilin); milk lactotransferrin (lactoferrin); egg white ovotransferrin (conalbumin); and membrane-associated melanotransferrin. Additional members of this family include inhibitor of carbonic anhydrase (ICA; mammals), major yolk protein (sea urchins), saxiphilin (frog), pacifastin (crayfish), and TTF-1 (algae). Most family members contain two transferrin-like domains of around 340 amino acids, the result of an ancient duplication event []. Each of the duplicated domains can be further divided into two subdomains that form a cleft inside of which the iron atom is bound in iron-transporting transferrin []. The iron-coordinating residues consist of an aspartic acid, two tyrosines and a histidine, as well as an arginine that coordinates a requisite anion. In addition to iron and anion liganding residues, the transferrin-like domain contains conserved cysteine residues involved in disulphide bond formation. Human lactoferrin is a serine peptidase belonging to MEROPS peptidase family S60, clan SR. It is found at high concentrations in all human secretions, where it plays a major role in mucosal defence. Lactoferrin cleaves IgA1 protease at an arginine-rich region defined by amino acids RRSRRSVR and digests Hap at a similar arginine-rich sequence (VRSRRAAR). Ser259 and Lys73 form a catalytic dyad, reminiscent of a number of bacterial serine proteases. ; GO: 0008199 ferric iron binding, 0006826 iron ion transport, 0006879 cellular iron ion homeostasis, 0005576 extracellular region; PDB: 1JNF_A 1TFD_A 1JW1_A 1DTZ_A 2J4U_X 1I6Q_A 1BIY_A 1CE2_A 1H76_A 1F9B_A ....

Note that this model does not identify all phnD-subfamily genes with evident phosphonate context, but all sequences above the trusted context may be inferred to bind phosphonate compounds even in the absence of such context. Furthermore, there is ample evidence to suggest that many other members of the TIGR01098 subfamily have a different primary function.
Also called lipid-A 4'-kinase. This essential gene encodes an enzyme in the pathway of lipid A biosynthesis in Gram-negative organisms. A single copy of this protein is found in Gram-negative bacteria. PSI-BLAST converges on this set of apparent orthologs without identifying any other homologs.
