STRINGSTRING
STRING protein interaction network
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

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)    
Predicted Functional Partners:
patA
Putrescine: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 [...]

gabT
4-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, [...]

puuD
Gamma-glutamyl-gamma-aminobutyrate hydrolase; Involved in the breakdown of putrescine via hydrolysis of the gamma-glutamyl linkage of gamma-glutamyl-gamma-aminobutyrate.
  
 
 0.952
ydcV
Putative ABC transporter permease; Involved in natural transformation. Probably part of the ABC transporter complex YdcSTUV. Probably responsible for the translocation of the substrate across the membrane. During natural transformation, may serve as the channel for dsDNA uptake (Probable).
  
 0.952
ydcS
Putative ABC transporter periplasmic binding protein; Catalyzes the formation of short polymers of R-3- hydroxybutyrate (cPHB). Involved in natural transformation. Probably part of the ABC transporter complex YdcSTUV. During natural transformation, may bind dsDNA and convey it to the inner membrane channel formed by YdcV (Probable). Belongs to the bacterial solute-binding protein PotD/PotF family.
 
  
 0.947
puuE
4-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.

truD
tRNA(Glu) pseudouridine(13) synthase; Responsible for synthesis of pseudouridine from uracil-13 in transfer RNAs.
   
  
 0.903
fmt
10-formyltetrahydrofolate:L-methionyl-tRNA(fMet) N-formyltransferase; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus. Belongs to the Fmt family.

ydcU
Putative ABC transporter permease; Probably part of the ABC transporter complex YdcSTUV. Probably responsible for the translocation of the substrate across the membrane.
 
    0.885
ydcT
Putative ABC transporter ATPase; Probably part of the ABC transporter complex YdcSTUV. Probably responsible for energy coupling to the transport system.
