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

Score
aatleucyl/phenylalanyl-tRNA-protein transferase; Functions in the N-end rule pathway of protein degradation where it conjugates Leu, Phe and, less efficiently, Met from aminoacyl- tRNAs to the N-termini of proteins containing an N-terminal arginine or lysine; Belongs to the L/F-transferase family. (234 aa)    
Predicted Functional Partners:
clpS
Regulatory protein for ClpA substrate specificity; Involved in the modulation of the specificity of the ClpAP- mediated ATP-dependent protein degradation.
 
  
 0.948
cydC
Glutathione/cysteine ABC transporter export permease/ATPase; Somehow involved in the cytochrome D branch of aerobic respiration. Seems to be a component of a transport system; Belongs to the ABC transporter superfamily. Cysteine exporter (TC 3.A.1.129.1) family.
  
    0.693
cydD
Glutathione/cysteine ABC transporter export permease/ATPase; Somehow involved in the cytochrome D branch of aerobic respiration. Seems to be a component of a transport system.
  
    0.683
clpA
ATPase and specificity subunit of ClpA-ClpP ATP-dependent serine protease, chaperone activity; ATP-dependent specificity component of the ClpAP protease. It directs the protease to specific substrates. It has unfoldase activity. The primary function of the ClpA-ClpP complex appears to be the degradation of unfolded or abnormal proteins.
 
  
 0.616
infA
Translation initiation factor IF-1; One of the essential components for the initiation of protein synthesis. Binds in the vicinity of the A-site. Stabilizes the binding of IF-2 and IF-3 on the 30S subunit to which N-formylmethionyl- tRNA(fMet) subsequently binds. Helps modulate mRNA selection, yielding the 30S pre-initiation complex (PIC). Upon addition of the 50S ribosomal subunit, IF-1, IF-2 and IF-3 are released leaving the mature 70S translation initiation complex.
  
 
 0.606
mnaT
Methionine N-acyltransferase; Acyltransferase that appears to be required for E.coli optimal growth rate and yield via the formation of N-acetylated amino acids. Catalyzes the acylation of L-methionine using acetyl-CoA or propanoyl-CoA as acyl donors, and the acetylation of L-phenylglycine. Is also able to N-acylate other free L-amino acids and their derivatives using a CoA thioester as cosubstrate. Using acetyl-CoA as an acyl donor, substrate specificity is methionine sulfone > methionine sulfoximine > methionine sulfoxide > methionine. Asparagine, lysine, glutamine, aspartate and glu [...]

trxB
Thioredoxin reductase, FAD/NAD(P)-binding; Thioredoxin reductase; Belongs to the class-II pyridine nucleotide-disulfide oxidoreductase family.
       0.496
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 [...]

tyrA
Chorismate mutase-T and prephenate dehydrogenase; Protein involved in L-phenylalanine biosynthetic process and tyrosine biosynthetic process.
 
   
 0.433
yjgM
GNAT family putative N-acetyltransferase; Putative acyltransferase; Belongs to the acetyltransferase family.
