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:
icdIsocitrate dehydrogenase, specific for NADP+; Protein involved in tricarboxylic acid cycle and anaerobic respiration; Belongs to the isocitrate and isopropylmalate dehydrogenases family. (416 aa)
puuE4-aminobutyrate aminotransferase, PLP-dependent; Catalyzes the transfer of the amino group from gamma- aminobutyrate (GABA) to alpha-ketoglutarate (KG) to yield succinic semialdehyde (SSA). PuuE is important for utilization of putrescine as the sole nitrogen or carbon source; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. (421 aa)
gadCGlutamate:gamma-aminobutyric acid antiporter; Involved in glutamate-dependent acid resistance. Imports glutamate inside the cell while simultaneously exporting to the periplasm the GABA produced by GadA and GadB. The gad system helps to maintain a near-neutral intracellular pH when cells are exposed to extremely acidic conditions. The ability to survive transit through the acidic conditions of the stomach is essential for successful colonization of the mammalian host by commensal and pathogenic bacteria; Belongs to the amino acid-polyamine-organocation (APC) superfamily. Glutamate:GABA [...] (511 aa)
gadBGlutamate decarboxylase B, PLP-dependent; Converts glutamate to gamma-aminobutyrate (GABA), consuming one intracellular proton in the reaction. The gad system helps to maintain a near-neutral intracellular pH when cells are exposed to extremely acidic conditions. The ability to survive transit through the acidic conditions of the stomach is essential for successful colonization of the mammalian host by commensal and pathogenic bacteria; Belongs to the group II decarboxylase family. (466 aa)
sadSuccinate semialdehyde dehydrogenase, NAD(P)+-dependent; Catalyzes the NAD(+)-dependent oxidation of succinate semialdehyde to succinate. It acts preferentially with NAD as cosubstrate but can also use NADP. Prevents the toxic accumulation of succinate semialdehyde (SSA) and plays an important role when arginine and putrescine are used as the sole nitrogen or carbon sources. (462 aa)
katECatalase HPII, heme d-containing; Decomposes hydrogen peroxide into water and oxygen; serves to protect cells from the toxic effects of hydrogen peroxide. (753 aa)
amyACytoplasmic alpha-amylase; Protein involved in carbohydrate catabolic process and polysaccharide catabolic process; Belongs to the glycosyl hydrolase 13 family. (495 aa)
gltXglutamyl-tRNA synthetase; Catalyzes the attachment of glutamate to tRNA(Glu) in a two- step reaction: glutamate is first activated by ATP to form Glu-AMP and then transferred to the acceptor end of tRNA(Glu). (471 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)
luxSS-ribosylhomocysteine lyase; Involved in the synthesis of autoinducer 2 (AI-2) which is secreted by bacteria and is used to communicate both the cell density and the metabolic potential of the environment. The regulation of gene expression in response to changes in cell density is called quorum sensing. Catalyzes the transformation of S-ribosylhomocysteine (RHC) to homocysteine (HC) and 4,5-dihydroxy-2,3-pentadione (DPD). Belongs to the LuxS family. (171 aa)
gltBGlutamate synthase, large subunit; Catalyzes the conversion of L-glutamine and 2-oxoglutarate into two molecules of L-glutamate. (1486 aa)
mdhMalate dehydrogenase, NAD(P)-binding; Catalyzes the reversible oxidation of malate to oxaloacetate. (312 aa)
gadAGlutamate decarboxylase A, PLP-dependent; Converts glutamate to gamma-aminobutyrate (GABA), consuming one intracellular proton in the reaction. The gad system helps to maintain a near-neutral intracellular pH when cells are exposed to extremely acidic conditions. The ability to survive transit through the acidic conditions of the stomach is essential for successful colonization of the mammalian host by commensal and pathogenic bacteria. (466 aa)
malSAlpha-amylase; Since only maltooligosaccharides up to a chain length of 6 glucose units are actively transported through the cytoplasmic membrane via the membrane-bound complex of three proteins, MalF, MalG, and MalK, longer maltooligosaccharides must first be degraded by the periplasmic alpha-amylase, the MalS protein; Belongs to the glycosyl hydrolase 13 family. (676 aa)
gltSGlutamate transporter; Catalyzes the sodium-dependent, binding-protein-independent transport of glutamate. Belongs to the glutamate:Na(+) symporter (ESS) (TC 2.A.27) family. (401 aa)
ppcPhosphoenolpyruvate carboxylase; Forms oxaloacetate, a four-carbon dicarboxylic acid source for the tricarboxylic acid cycle. (883 aa)
