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

proCPyrroline-5-carboxylate reductase; Catalyzes the reduction of 1-pyrroline-5-carboxylate (PCA) to L-proline. (274 aa)    
Predicted Functional Partners:
MCA1536
Conserved hypothetical protein TIGR00044; Pyridoxal 5'-phosphate (PLP)-binding protein, which is involved in PLP homeostasis; Belongs to the pyridoxal phosphate-binding protein YggS/PROSC family.
  
 0.959
proB
Glutamate 5-kinase; Catalyzes the transfer of a phosphate group to glutamate to form L-glutamate 5-phosphate.
 
 0.931
pip
Proline iminopeptidase; Identified by similarity to SP:P52279; match to protein family HMM PF00561; match to protein family HMM TIGR01249; Belongs to the peptidase S33 family.
    
  0.901
MCA1534
Identified by match to protein family HMM PF02325.
 
    0.871
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.
 
 
 0.798
MCA3023
Ham1 protein; 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.
      0.691
pheA
Chorismate mutase/prephenate dehydratase; Identified by similarity to SP:P27603; match to protein family HMM PF00800; match to protein family HMM PF01817; match to protein family HMM PF01842; match to protein family HMM TIGR01807.
 
   
 0.553
gltB
Glutamate synthase, large subunit; Identified by similarity to SP:P39812; match to protein family HMM PF01493; match to protein family HMM PF01645; match to protein family HMM PF04897; match to protein family HMM PF04898.
     
 0.550
guaA
GMP synthase; Catalyzes the synthesis of GMP from XMP.
     
 0.534
MCA2627
DNA internalization-related competence protein ComEC/Rec2; Identified by match to protein family HMM PF00753; match to protein family HMM PF03772; match to protein family HMM TIGR00360; match to protein family HMM TIGR00361.
