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. (543 aa)    
Predicted Functional Partners:
AFZ48097.1
PFAM: IMP dehydrogenase / GMP reductase domain; TIGRFAM: IMP dehydrogenase family protein; COGs: COG0516 IMP dehydrogenase/GMP reductase; InterPro IPR001093:IPR005992; KEGG: cyh:Cyan8802_0372 IMP dehydrogenase family protein; PFAM: IMP dehydrogenase/GMP reductase; SPTR: IMP dehydrogenase family protein; TIGRFAM: IMP dehydrogenase family protein.

apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
  
 0.996
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.
  
 
 0.985
rplK
LSU ribosomal protein L11P; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors.
   
    0.977
AFZ48325.1
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.
 
 
 0.976
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
 
 
 0.972
AFZ47632.1
Hypothetical protein; KEGG: cyc:PCC7424_0116 DALR anticodon binding domain protein; SPTR: DALR anticodon binding domain protein.
   
  
 0.972
argS
arginyl-tRNA synthetase; PFAM: DALR anticodon binding domain; Arginyl tRNA synthetase N terminal domain; tRNA synthetases class I (R); TIGRFAM: arginyl-tRNA synthetase; COGs: COG0018 Arginyl-tRNA synthetase; InterProIPR005148:IPR015945:IPR008909:IPR001412:IPR 001278; KEGG: cyh:Cyan8802_0542 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: Arginyl-tRNA synthetase; TIGRFAM: arginyl-tRNA synthetase.

tuf
Translation elongation factor 1A (EF-1A/EF-Tu); This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis.
  
  
 0.967
purL
Phosphoribosylformylglycinamidine synthase II; Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is thought to assist [...]
