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
proAGamma-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. (430 aa)    
Predicted Functional Partners:
proB
Glutamate 5-kinase; Catalyzes the transfer of a phosphate group to glutamate to form L-glutamate 5-phosphate.
 
 0.999
proC
Pyrroline-5-carboxylate reductase; Catalyzes the reduction of 1-pyrroline-5-carboxylate (PCA) to L-proline.
 
 
 0.960
obg
GTP1/OBG-family GTP-binding protein; An essential GTPase which binds GTP, GDP and possibly (p)ppGpp with moderate affinity, with high nucleotide exchange rates and a fairly low GTP hydrolysis rate. Plays a role in control of the cell cycle, stress response, ribosome biogenesis and in those bacteria that undergo differentiation, in morphogenesis control. Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. OBG GTPase family.
  
  
 0.851
atpA
ATP synthase alpha chain; Produces ATP from ADP in the presence of a proton gradient across the membrane. The alpha chain is a regulatory subunit. Belongs to the ATPase alpha/beta chains family.
 
    
 0.849
nadD
Putative nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).

rsfS
Conserved hypothetical protein; Functions as a ribosomal silencing factor. Interacts with ribosomal protein L14 (rplN), blocking formation of intersubunit bridge B8. Prevents association of the 30S and 50S ribosomal subunits and the formation of functional ribosomes, thus repressing translation.
     
 0.786
DIP1772
Similar to Mycobacterium tuberculosis hypothetical protein Rv2417c TR:P71726 (EMBL:Z81368) (280 aa) fasta scores: E(): 1e-21, 34.92% id in 272 aa, and to Streptomyces coelicolor hypothetical protein SCC123.07c TR:Q9RDL7 (EMBL:AL136518) (281 aa) fasta scores: E(): 6e-21, 36.13% id in 274 aa.
