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

Lspi_0941Spermidine synthase. (243 aa)    
Predicted Functional Partners:
astD
Succinylglutamic-5-semialdehyde dehydrogenase; Catalyzes the NAD-dependent reduction of succinylglutamate semialdehyde into succinylglutamate.
 
 0.849
Lspi_0382
Flagellar protein; FliM is one of three proteins (FliG, FliN, FliM) that forms the rotor-mounted switch complex (C ring), located at the base of the basal body. This complex interacts with the CheY and CheZ chemotaxis proteins, in addition to contacting components of the motor that determine the direction of flagellar rotation.
    
   0.830
cpg2_1
Carboxypeptidase G2.
 
   
 0.827
astA
Arginine N-succinyltransferase, beta chain.
       0.801
astB
Succinylarginine dihydrolase; Catalyzes the hydrolysis of N(2)-succinylarginine into N(2)- succinylornithine, ammonia and CO(2).
       0.801
lysAC
Diaminopimelate decarboxylase, aspartate kinase (fusion of lysA and lysC); Belongs to the Orn/Lys/Arg decarboxylase class-II family.
  
 0.733
hutG
Formimidoylglutamase; Catalyzes the conversion of N-formimidoyl-L-glutamate to L- glutamate and formamide; Belongs to the arginase family.
  
 
 0.727
Lspi_1019
Hydrolase.
  
 
 0.711
Lspi_0290
Spermidine synthase.
 
  
  0.700
xapA
Purine nucleoside phosphorylase; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate.
