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

KWV95961.1Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology. (343 aa)    
Predicted Functional Partners:
guaA
GMP synthetase; Catalyzes the synthesis of GMP from XMP.
  
 
 0.803
guaB
IMP dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
     
 0.680
KWV94228.1
Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
  
 0.643
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase; Involved in de novo purine biosynthesis; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
  0.547
KWV95960.1
Short-chain dehydrogenase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the short-chain dehydrogenases/reductases (SDR) family.
       0.523
purA
Adenylosuccinate synthetase; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.
     
 0.466
KWV94971.1
Glutamate synthase subunit alpha; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
  0.461
KWV95995.1
Non-canonical purine NTP 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.
    
  0.440
uppP
UDP-diphosphatase; Catalyzes the dephosphorylation of undecaprenyl diphosphate (UPP). Confers resistance to bacitracin; Belongs to the UppP family.
 
     0.433
ychF
GTP-binding protein; ATPase that binds to both the 70S ribosome and the 50S ribosomal subunit in a nucleotide-independent manner.
       0.409
