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

STY0163GMP reductase; Catalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides. (347 aa)    
Predicted Functional Partners:
STY2751
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
 
 0.997
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.
 
 
 0.973
STY2675
Putative amidotransferase; Similar, in part, to Salmonella typhimurium LT2 hypothetical protein yfeJ SW:YFEJ_SALTY (P40194) (170 aa) fasta scores: E(): 0, 89.0% id in 155 aa. The similarity ends due to a deletion in S. typhimurium with respect to S. typhi. Similar to Zymomonas mobilis hypothetical protein TR:Q9RQD2 (EMBL:AF117351) (251 aa) fasta scores: E(): 0, 53.1% id in 239 aa and Pseudomonas aeruginosa probable glutamine amidotransferase PA0531 TR:AAG03920 (EMBL:AE004489) (238 aa) fasta scores: E(): 2.1e-16, 31.9% id in 238 aa.

STY3709
Phosphoribosylaminoimidazolecarboxamide formyltransferase; Orthologue of E. coli purH (PUR9_ECOLI); Fasta hit to PUR9_ECOLI (529 aa), 94% identity in 529 aa overlap.
  
 
 0.947
STY2752
Inosine-5'-monophosphate 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.
 
 
0.930
STY0527
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 
 0.926
STY0362
Xanthine-guanine phosphoribosyltransferase; Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily.
  
 
 0.921
STY4052
5'guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
    
 0.917
STY3052
Stationary-phase survival protein; Nucleotidase with a broad substrate specificity as it can dephosphorylate various ribo- and deoxyribonucleoside 5'-monophosphates and ribonucleoside 3'-monophosphates with highest affinity to 3'-AMP. Also hydrolyzes polyphosphate (exopolyphosphatase activity) with the preference for short-chain-length substrates (P20-25). Might be involved in the regulation of dNTP and NTP pools, and in the turnover of 3'-mononucleotides produced by numerous intracellular RNases (T1, T2, and F) during the degradation of various RNAs.
    
 0.916
STY0192
Hypoxanthine phosphoribosyltransferase; Orthologue of E. coli hpt (HPRT_ECOLI); Fasta hit to HPRT_ECOLI (182 aa), 95% identity in 171 aa overlap; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
