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
putPProline permease; Catalyzes the high-affinity uptake of extracellular proline. Important for the use of proline as a sole carbon and energy source or a sole nitrogen source. (473 aa)    
Predicted Functional Partners:
putB
Proline oxidase; Converts proline to delta-1-pyrroline-5-carboxylate. Important for the use of proline as a sole carbon and energy source or a sole nitrogen source.
  
  
 0.907
putR
Transcriptional activator of proline degradation operon; Activates transcription of the putBCP operon. Requires proline as a coactivator.
  
  
 0.875
opuD
Glycine betaine transporter; High-affinity uptake of glycine betaine. Does not mediate either carnitine or choline uptake; Belongs to the BCCT transporter (TC 2.A.15) family.
 
  
 0.823
putC
1-pyrroline-5-carboxylate dehydrogenase; Important for the use of proline as a sole carbon and energy source or a sole nitrogen source.
  
  
 0.822
trpB
Tryptophan synthase (beta subunit); The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.
      
 0.714
pabB
4-amino-4-deoxychorismate synthase (para-aminobenzoate synthase); Part of a heterodimeric complex that catalyzes the two-step biosynthesis of 4-amino-4-deoxychorismate (ADC), a precursor of p- aminobenzoate (PABA) and tetrahydrofolate. In the first step, a glutamine amidotransferase (PabA) generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by aminodeoxychorismate synthase (PabB) to produce ADC.
      
 0.701
proA
Gamma-glutamyl phosphate reductase; Catalyzes the NADPH-dependent reduction of L-glutamate 5- phosphate into L-glutamate 5-semialdehyde and phosphate. The product spontaneously undergoes cyclization to form 1-pyrroline-5-carboxylate. Belongs to the gamma-glutamyl phosphate reductase family.
     
 0.669
putM
Proline dehydrogenase 1; Converts proline to delta-1-pyrroline-5-carboxylate.
  
  
 0.631
trpA
Tryptophan synthase (alpha subunit); The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate; Belongs to the TrpA family.
      
 0.625
proB
Glutamate 5-kinase; Catalyzes the transfer of a phosphate group to glutamate to form L-glutamate 5-phosphate.
      
 0.608
