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

guaAGMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP. (509 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
purD
Phosphoribosylamine--glycine ligase/phosphoribosylaminoimidazole carboxylase, PurE protein; Catalyzes the conversion of N5-carboxyaminoimidazole ribonucleotide (N5-CAIR) to 4-carboxy-5-aminoimidazole ribonucleotide (CAIR); Belongs to the GARS family.
 
  
 0.995
argS
arginyl-tRNA synthetase; PFAM: DALR anticodon binding domain; Arginyl tRNA synthetase N terminal domain; tRNA synthetases class I (R); TIGRFAM: arginyl-tRNA synthetase.
  
  
 0.995
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 0.993
pheT
phenylalanyl-tRNA synthetase, beta subunit; PFAM: tRNA synthetase B5 domain; Ferredoxin-fold anticodon binding domain; B3/4 domain; Putative tRNA binding domain; TIGRFAM: phenylalanyl-tRNA synthetase, beta subunit, non-spirochete bacterial; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily.
  
  
 0.991
rplK
50S ribosomal protein L11; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors.
   
    0.989
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.
  
 0.980
map
Methionine aminopeptidase, type I; Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val). Requires deformylation of the N(alpha)-formylated initiator methionine before it can be hydrolyzed; Belongs to the peptidase M24A family. Methionine aminopeptidase type 1 subfamily.
  
  
 0.979
hisH
Imidazole glycerol phosphate synthase, glutamine amidotransferase subunit; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisH subunit catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the synthesis of IGP and AICAR. The resulting ammonia molecule is channeled to the active site of HisF; Belongs to the HisA/HisF family.
    
 0.975
metG
Protein containing C-terminal region/beta chain of methionyl-tRNA synthetase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
