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; Catalyzes the synthesis of GMP from XMP. (501 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
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
 
 
 0.993
TM_0206
Hypoxanthine phosphoribosyltransferase; Similar to GB:D26185 SP:P37472 PID:467457 GB:AL009126 percent identity: 66.67; identified by sequence similarity; putative; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
  
 
 0.982
TM_0159
Ham1 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.
 
 
 0.980
surE
Stationary phase survival protein; Nucleotidase that preferentially dephosphorylates 5'-GMP and 5'-AMP.
    
 0.980
argS
arginyl-tRNA synthetase; Similar to SP:P46906 PID:971336 PID:2224756 GB:AL009126 percent identity: 67.62; identified by sequence similarity; putative.
  
  
 0.968
valS
valyl-tRNA synthetase; Catalyzes the attachment of valine to tRNA(Val). As ValRS can inadvertently accommodate and process structurally similar amino acids such as threonine, to avoid such errors, it has a 'posttransfer' editing activity that hydrolyzes mischarged Thr-tRNA(Val) in a tRNA- dependent manner; Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 1 subfamily.

TM_1878
UDP-sugar hydrolase; Similar to SP:P07024 PID:757842 GB:U00096 PID:1773162 PID:1786687 percent identity: 62.97; identified by sequence similarity; putative; Belongs to the 5'-nucleotidase family.
    
 0.957
pyrG
CTP synthetase; 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.
  
 
 0.955
mazG
mazG protein; Catalyzes the hydrolysis of all eight canonical ribonucleoside triphosphates (NTP) and deoxyribonucleoside triphosphates (dNTP) to their corresponding nucleoside monophosphates ((d)NMP) and PPi and subsequently hydrolyzes the resultant PPi to Pi. The NTPase activity with deoxyribonucleoside triphosphates as substrate is higher than corresponding ribonucleoside triphosphates. dGTP is the best substrate among the deoxyribonucleoside triphosphates, and GTP is the best among the ribonucleoside triphosphates.
