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

guaBInosine-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. (487 aa)    
Predicted Functional Partners:
guaA
Putative GMP synthase; Catalyzes the synthesis of GMP from XMP.
 
 0.999
adeK
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.
 
 
 0.993
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase; Similar to Escherichia coli bifunctional purine biosynthesis protein PurH SW:PUR9_ECOLI (P15639) (529 aa) fasta scores: E(): 0, 87.1% id in 529 aa, and to Salmonella typhimurium bifunctional purine biosynthesis protein PurH SW:PUR9_SALTY (P26978) (508 aa) fasta scores: E(): 0, 86.8% id in 508 aa.

YPO2295
Haloacid dehalogenase-like hydrolase family protein; Similar to Vibrio cholerae hypothetical protein VCA0608 TR:Q9KLY3 (EMBL:AE004391) (224 aa) fasta scores: E(): 0, 62.9% id in 224 aa; Similar to Vibrio cholerae hypothetical protein VCA0608 TR:Q9KLY3 (EMBL:AE004391) (224 aa) fasta scores: E(): 0, 62.9% id in 224 aa, and to Escherichia coli hypothetical protein YjjG SW:YJJG_ECOLI (P33999) (225 aa) fasta scores: E(): 0, 56.8% id in 222 aa.
   
 
 0.966
YPO0945
Conserved hypothetical protein; 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.
  
 0.956
surE
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.

b0125
Similar to Escherichia coli hypoxanthine phosphoribosyltransferase Hpt or B0125 SW:HPRT_ECOLI (P36766) (182 aa) fasta scores: E(): 0, 87.1% id in 178 aa,and to Salmonella typhimurium hypoxanthine phosphoribosyltransferase Hpt SW:HPRT_SALTY (O33799) (178 aa) fasta scores: E(): 0, 87.6% id in 178 aa; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
    
 0.948
gpp
Xanthine-guanine phosphoribosyltransferase; Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily.
  
 
 0.947
guaC
GMP 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.
  
 
 
0.946
YPO0141
Similar to Escherichia coli hypothetical protein YrfG SW:YRFG_ECOLI (P45801) (222 aa) fasta scores: E(): 0,67.0% id in 221 aa.
