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

proCPyrroline-5-carboxylate reductase; Catalyzes the reduction of 1-pyrroline-5-carboxylate (PCA) to L-proline. (270 aa)    
Predicted Functional Partners:
sepF
Hypothetical protein; Cell division protein that is part of the divisome complex and is recruited early to the Z-ring. Probably stimulates Z-ring formation, perhaps through the cross-linking of FtsZ protofilaments. Its function overlaps with FtsA.
     
 0.830
proB
Glutamate 5-kinase; Catalyzes the transfer of a phosphate group to glutamate to form L-glutamate 5-phosphate.
 
 
 0.805
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.
 
 
 0.784
EV02_0809
Hypothetical protein; Pyridoxal 5'-phosphate (PLP)-binding protein, which is involved in PLP homeostasis; Belongs to the pyridoxal phosphate-binding protein YggS/PROSC family.
 
  
 0.687
EV02_0810
Hypothetical protein; Alternative locus ID: PSB_0278; FIG023675: hypothetical protein.
   
 
 0.636
EV02_1446
Ferredoxin-dependent glutamate synthase; Alternative locus ID: PSB_0915.
     
 0.605
EV02_0889
Aldehyde dehydrogenase; Alternative locus ID: PSB_0357; Belongs to the aldehyde dehydrogenase family.
    
 0.583
EV02_0811
Transmembrane component of energizing module of ECF transporters in Cyanobacteria; Alternative locus ID: PSB_0279.
     
 0.556
der
GTP-binding protein EngA; GTPase that plays an essential role in the late steps of ribosome biogenesis; Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. EngA (Der) GTPase family.
     
 0.555
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
     
 0.551
