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:
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)
speFOrnithine decarboxylase isozyme, inducible; Protein involved in polyamine biosynthetic process; Belongs to the Orn/Lys/Arg decarboxylase class-I family. (732 aa)
puuPPutrescine importer; Involved in the uptake of putrescine. Belongs to the amino acid-polyamine-organocation (APC) superfamily. (461 aa)
puuAGlutamate--putrescine ligase; Involved in the breakdown of putrescine via the biosynthesis of gamma-L-glutamylputrescine. It is able to use several diamines, spermidine and spermine. Absolutely essential to utilize putrescine as both nitrogen and carbon sources and to decrease the toxicity of putrescine, which can lead to inhibition of cell growth and protein synthesis; Belongs to the glutamine synthetase family. (472 aa)
puuDGamma-glutamyl-gamma-aminobutyrate hydrolase; Involved in the breakdown of putrescine via hydrolysis of the gamma-glutamyl linkage of gamma-glutamyl-gamma-aminobutyrate. (254 aa)
puuRRepressor for the divergent puu operons, putrescine inducible; Represses puuA, puuD and puuP. (185 aa)
puuCGamma-glutamyl-gamma-aminobutyraldehyde dehydrogenase; Catalyzes the oxidation of 3-hydroxypropionaldehyde (3-HPA) to 3-hydroxypropionic acid (3-HP). It acts preferentially with NAD but can also use NADP. 3-HPA appears to be the most suitable substrate for PuuC followed by isovaleraldehyde, propionaldehyde, butyraldehyde, and valeraldehyde. It might play a role in propionate and/or acetic acid metabolisms. Also involved in the breakdown of putrescine through the oxidation of gamma-Glu-gamma-aminobutyraldehyde to gamma-Glu-gamma-aminobutyrate (gamma-Glu-GABA). (495 aa)
puuBGamma-glutamylputrescine oxidoreductase; Involved in the breakdown of putrescine via the oxidation of L-glutamylputrescine. (426 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)
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)
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)
speBAgmatinase; Catalyzes the formation of putrescine from agmatine. (306 aa)
speABiosynthetic arginine decarboxylase, PLP-binding; Catalyzes the biosynthesis of agmatine from arginine. Belongs to the Orn/Lys/Arg decarboxylase class-II family. SpeA subfamily. (658 aa)
speCOrnithine decarboxylase, constitutive; Ornithine decarboxylase isozyme; Protein involved in polyamine biosynthetic process. (711 aa)
