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

HI_0692Xanthine-guanine phosphoribosyltransferase (gptB); Similar to SP:P26972 GB:X52093 GB:X63336 PID:47695 percent identity: 74.03; identified by sequence similarity; putative. (155 aa)    
Predicted Functional Partners:
guaA
GMP synthase (guaA); Catalyzes the synthesis of GMP from XMP.
  
 0.934
HI_0221.1
Predicted coding region HI0221.1; Brute Force ORF; identified by GeneMark; putative; Belongs to the IMPDH/GMPR family.
  
 
 0.852
guaB
Inosine-5'-monophosphate dehydrogenase (guaB); 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.
  
 
 0.818
hisI
phosphoribosyl-AMP cyclohydrolase / phosphoribosyl-ATP pyrophosphohydrolase (hisIE); Similar to SP:P06989 GB:D43637 GB:U02072 GB:X03974 PID:41700 percent identity: 61.22; identified by sequence similarity; putative; In the C-terminal section; belongs to the PRA-PH family.
    
 0.705
infB
Translation initiation factor 2 (infB); One of the essential components for the initiation of protein synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis and promotes its binding to the 30S ribosomal subunits. Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex (By similarity); Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. IF-2 subfamily.
  
 
  0.701
purL
Phosphoribosylformylglycinamidine synthase (purL); Phosphoribosylformylglycinamidine synthase involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate.
  
  
 0.638
purB
Adenylosuccinate lyase (purB); Similar to GB:M74924 SP:P25739 PID:145203 PID:42585 GB:U00096 percent identity: 76.97; identified by sequence similarity; putative.
  
 0.580
gmk
Guanylate kinase (gmk); Essential for recycling GMP and indirectly, cGMP.
   
 
 0.513
kdgK
2-dehydro-3-deoxygluconokinase (kdgK); Catalyzes the phosphorylation of 2-keto-3-deoxygluconate (KDG) to produce 2-keto-3-deoxy-6-phosphogluconate (KDPG).
   
 0.479
rbsK
Ribokinase (rbsK); Catalyzes the phosphorylation of ribose at O-5 in a reaction requiring ATP and magnesium. The resulting D-ribose-5-phosphate can then be used either for sythesis of nucleotides, histidine, and tryptophan, or as a component of the pentose phosphate pathway.
