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.

guaAGMP synthase [glutamine-hydrolyzing]; Catalyzes the synthesis of GMP from XMP. (525 aa)    
Predicted Functional Partners:
guaB
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.
 
 0.999
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.
 
 0.998
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
 
 
 0.992
purL
Phosphoribosylformylglycinamidine synthase; 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.
 
  
 0.987
gpt
Xanthine-guanine phosphoribosyltransferase; Acts on guanine, xanthine and to a lesser extent hypoxanthine; Belongs to the purine/pyrimidine phosphoribosyltransferase family. XGPT subfamily.
  
 0.987
hpt
Similar to Salmonella typhimurium hypoxanthine phosphoribosyltransferase Hpt or stm0170 SWALL:HPRT_SALTY (SWALL:O33799) (178 aa) fasta scores: E(): 1.2e-54, 86.2% id in 174 aa, and to Escherichia coli, Escherichia coli O6, and Shigella flexneri hypoxanthine phosphoribosyltransferase Hpt or b0125 or c0154 or sf0122 SWALL:HPRT_ECOLI (SWALL:P36766) (178 aa) fasta scores: E(): 2.4e-54, 84.48% id in 174 aa; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.983
ECA3631
Ham1 protein homolog; 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.
 
 
 0.983
argS
Similar to Escherichia coli arginyl-tRNA synthetase ArgS or b1876 SWALL:SYR_ECOLI (SWALL:P11875) (577 aa) fasta scores: E(): 4.1e-183, 80.24% id in 577 aa.
  
  
 0.962
pyrG
CTP synthase; Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates.
  
 
 0.958
ECA3005
Similar to Ralstonia solanacearum putative glutamine amidotransferase protein rsc0213 or rs00645 SWALL:Q8Y2W9 (EMBL:AL646058) (238 aa) fasta scores: E(): 9e-37, 45.37% id in 238 aa, and to Xylella fastidiosa GMP synthase xf0560 SWALL:Q9PFU7 (EMBL:AE003903) (240 aa) fasta scores: E(): 1.1e-28, 43.8% id in 242 aa.
