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
proCPyrroline-5-carboxylate reductase; Catalyzes the reduction of 1-pyrroline-5-carboxylate (PCA) to L-proline. (273 aa)    
Predicted Functional Partners:
putA_1
Bifunctional protein PutA; Oxidizes proline to glutamate for use as a carbon and nitrogen source; Belongs to the aldehyde dehydrogenase family. In the N-terminal section; belongs to the proline dehydrogenase family.
   
 0.956
APC11735.1
4-hydroxyproline epimerase; Belongs to the proline racemase family.
    
 0.920
yggS
Hypothetical protein; Pyridoxal 5'-phosphate (PLP)-binding protein, which is involved in PLP homeostasis.
 
  
 0.849
APC10658.1
YGGT family protein.
  
    0.809
proB
Glutamate 5-kinase; Catalyzes the transfer of a phosphate group to glutamate to form L-glutamate 5-phosphate.
 
 
 0.803
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.
 
 
 0.801
rdgB
dITP/XTP pyrophosphatase; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family.
 
     0.770
rnhA
Ribonuclease HI; Endonuclease that specifically degrades the RNA of RNA-DNA hybrids.
      0.622
argD
Acetylornithine/succinyldiaminopimelate aminotransferase; Involved in both the arginine and lysine biosynthetic pathways; Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family. ArgD subfamily.
 
  
 0.613
guaA
GMP synthase [glutamine-hydrolyzing]; Catalyzes the synthesis of GMP from XMP.
 
   
 0.596
