Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology
Your Input:
glnDUridylyltransferase; Modifies, by uridylylation and deuridylylation, the PII regulatory proteins GlnB and GlnK, in response to the nitrogen status of the cell that GlnD senses through the glutamine level. Under low glutamine levels, catalyzes the conversion of the PII proteins and UTP to PII-UMP and PPi, while under higher glutamine levels, GlnD hydrolyzes PII-UMP to PII and UMP (deuridylylation). Thus, controls uridylylation state and activity of the PII proteins, and plays an important role in the regulation of nitrogen assimilation and metabolism. (890 aa)
ynfMPutative arabinose efflux transporter; Putative transport protein. (417 aa)
gabDSuccinate-semialdehyde dehydrogenase I, NADP-dependent; Catalyzes the NADP(+)-dependent oxidation of succinate semialdehyde to succinate. Thereby functions in a GABA degradation pathway that allows some E.coli strains to utilize GABA as a nitrogen source for growth. Also catalyzes the conversion of glutarate semialdehyde to glutarate, as part of a L- lysine degradation pathway that proceeds via cadaverine, glutarate and L-2-hydroxyglutarate. (482 aa)
gabT4-aminobutyrate aminotransferase, PLP-dependent; Pyridoxal phosphate-dependent enzyme that catalyzes transamination between primary amines and alpha-keto acids. Catalyzes the transfer of the amino group from gamma-aminobutyrate (GABA) to alpha-ketoglutarate (KG) to yield succinic semialdehyde (SSA) and glutamate. Thereby functions in a GABA degradation pathway that allows some E.coli strains to utilize GABA as a nitrogen source for growth. Also catalyzes the conversion of 5-aminovalerate to glutarate semialdehyde, as part of a L-lysine degradation pathway that proceeds via cadaverine, [...] (426 aa)
mscSMechanosensitive channel protein, small conductance; Mechanosensitive channel that participates in the regulation of osmotic pressure changes within the cell, opening in response to stretch forces in the membrane lipid bilayer, without the need for other proteins. Contributes to normal resistance to hypoosmotic shock. Forms an ion channel of 1.0 nanosiemens conductance with a slight preference for anions. The channel is sensitive to voltage; as the membrane is depolarized, less tension is required to open the channel and vice versa. The channel is characterized by short bursts of activ [...] (286 aa)
speCOrnithine decarboxylase, constitutive; Ornithine decarboxylase isozyme; Protein involved in polyamine biosynthetic process. (711 aa)
patAPutrescine:2-oxoglutaric acid aminotransferase, PLP-dependent; Catalyzes the aminotransferase reaction from putrescine to 2- oxoglutarate, leading to glutamate and 4-aminobutanal, which spontaneously cyclizes to form 1-pyrroline. This is the first step in one of two pathways for putrescine degradation, where putrescine is converted into 4- aminobutanoate (gamma-aminobutyrate or GABA) via 4-aminobutanal, which allows E.coli to grow on putrescine as the sole nitrogen source. Also functions as a cadaverine transaminase in a a L-lysine degradation pathway to succinate that proceeds via cad [...] (459 aa)
gltDGlutamate synthase, 4Fe-4S protein, small subunit; Catalyzes the conversion of L-glutamine and 2-oxoglutarate into two molecules of L-glutamate. (472 aa)
glnAGlutamine synthetase; Catalyzes the ATP-dependent biosynthesis of glutamine from glutamate and ammonia. (469 aa)
ldcCLysine decarboxylase 2, constitutive; Plays a role in lysine utilization by acting as a lysine decarboxylase. (713 aa)
glnKNitrogen assimilation regulatory protein for GlnL, GlnE, and AmtB; P-II indirectly controls the transcription of the glutamine synthetase gene (glnA). P-II prevents NR-II-catalyzed conversion of NR- I to NR-I-phosphate, the transcriptional activator of GlnA. When P-II is uridylylated to P-II-UMP, these events are reversed. When the ratio of Gln to 2-ketoglutarate decreases, P-II is uridylylated to P-II-UMP, which causes the deadenylation of glutamine synthetase by GlnE, so activating the enzyme (By similarity); Belongs to the P(II) protein family. (112 aa)
amtBAmmonium transporter; Involved in the uptake of ammonia; Belongs to the ammonia transporter channel (TC 1.A.11.2) family. (428 aa)
glxRTartronate semialdehyde reductase, NADH-dependent; Protein involved in carbohydrate catabolic process, glycolate metabolic process and allantoin assimilation pathway; Belongs to the HIBADH-related family. (292 aa)
speFOrnithine decarboxylase isozyme, inducible; Protein involved in polyamine biosynthetic process; Belongs to the Orn/Lys/Arg decarboxylase class-I family. (732 aa)
patDGamma-aminobutyraldehyde dehydrogenase; Catalyzes the oxidation 4-aminobutanal (gamma- aminobutyraldehyde) to 4-aminobutanoate (gamma-aminobutyrate or GABA). This is the second step in one of two pathways for putrescine degradation, where putrescine is converted into 4-aminobutanoate via 4-aminobutanal, which allows E.coli to grow on putrescine as the sole nitrogen source. Also functions as a 5-aminopentanal dehydrogenase in a a L-lysine degradation pathway to succinate that proceeds via cadaverine, glutarate and L-2-hydroxyglutarate. Can also oxidize n-alkyl medium-chain aldehydes, bu [...] (474 aa)
