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. (268 aa)    
Predicted Functional Partners:
putA
Bifunctional protein PutA; Function of strongly homologous gene; enzyme; Belongs to the aldehyde dehydrogenase family.
 
 0.945
yggS
Conserved protein of unknown function, UPF0001; Pyridoxal 5'-phosphate (PLP)-binding protein, which is involved in PLP homeostasis; Belongs to the pyridoxal phosphate-binding protein YggS/PROSC family.
  
 0.935
proC-2
Pyrroline-5-carboxylate reductase; Catalyzes the reduction of 1-pyrroline-5-carboxylate (PCA) to L-proline.
  
  
 
0.903
NIDE0771
Conserved protein of unknown function, YggT family; Homologs of previously reported genes of unknown function.
 
    0.881
NIDE0772
Putative Cell division protein DivIVA; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative factor.
     
 0.792
proB
Glutamat 5-kinase; Catalyzes the transfer of a phosphate group to glutamate to form L-glutamate 5-phosphate.
 
 0.781
NIDE0768
Conserved protein of unknown function, DUF152; Homologs of previously reported genes of unknown function; ; Belongs to the multicopper oxidase YfiH/RL5 family.
       0.634
ftsZ
Cell division protein FtsZ; Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity.
     
 0.620
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.
 
 
 0.618
NIDE0773
Putative Esterase, beta-lactamase family; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
     
 0.617
