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, large subunit; Catalyzes the synthesis of GMP from XMP. (517 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.

COGs: COG0018 Arginyl-tRNA synthetase; InterProIPR005148:IPR015945:IPR008909:IPR014729:IPR 009080:IPR001412:IPR001278; KEGG: pca:Pcar_0742 arginyl-tRNA synthetase; PFAM: Arginyl-tRNA synthetase, class Ic, core; arginyl tRNA synthetase domain protein; DALR anticodon binding domain protein; PRIAM: Arginine--tRNA ligase; SPTR: Q3A6K6 Arginyl-tRNA synthetase; TIGRFAM: arginyl-tRNA synthetase; PFAM: DALR anticodon binding domain; Arginyl tRNA synthetase N terminal domain; tRNA synthetases class I (R); TIGRFAM: arginyl-tRNA synthetase.

Deba_0490
Non-canonical purine NTP pyrophosphatase, rdgB/HAM1 family; 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.
 
 
 0.979
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.
  
 
 0.974
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
 
 
 0.968
rplK
Ribosomal protein L11; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors.

Deba_1086
COGs: COG0634 Hypoxanthine-guanine phosphoribosyltransferase; InterPro IPR000836:IPR005904; KEGG: sfu:Sfum_1422 hypoxanthine phosphoribosyltransferase; PFAM: phosphoribosyltransferase; PRIAM: Hypoxanthine phosphoribosyltransferase; SPTR: A0LI61 Hypoxanthine phosphoribosyltransferase; TIGRFAM: hypoxanthine phosphoribosyltransferase; PFAM: Phosphoribosyl transferase domain; TIGRFAM: hypoxanthine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.

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.
  
  
 0.964
surE
Stationary-phase survival protein SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.961
lysS
COGs: COG1190 Lysyl-tRNA synthetase (class II); InterProIPR018149:IPR004365:IPR004364:IPR016027:IPR 006195:IPR012340:IPR002313; KEGG: drt:Dret_2234 lysyl-tRNA synthetase; PFAM: tRNA synthetase class II (D K and N); nucleic acid binding OB-fold tRNA/helicase-type; SPTR: C8X521 Lysyl-tRNA synthetase; TIGRFAM: lysyl-tRNA synthetase; PFAM: tRNA synthetases class II (D, K and N); OB-fold nucleic acid binding domain; TIGRFAM: lysyl-tRNA synthetase, eukaryotic and non-spirochete bacterial; Belongs to the class-II aminoacyl-tRNA synthetase family.
