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.

Score
guaBInosine-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. (509 aa)    
Predicted Functional Partners:
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.

purA
Adenylosuccinate synthetase; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.

Isop_1836
COGs: COG0634 Hypoxanthine-guanine phosphoribosyltransferase; InterPro IPR000836: IPR005904; KEGG: psl:Psta_1642 hypoxanthine phosphoribosyltransferase; PFAM: phosphoribosyltransferase; PRIAM: Hypoxanthine phosphoribosyltransferase; SPTR: Hypoxanthine phosphoribosyltransferase; TIGRFAM: hypoxanthine phosphoribosyltransferase; PFAM: Phosphoribosyl transferase domain; TIGRFAM: hypoxanthine phosphoribosyltransferase; Belongs to the purine/pyrimidine phosphoribosyltransferase family.
    
 0.952
surE
5'-nucleotidase; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
    
 0.945
Isop_3030
Stationary-phase survival protein SurE; COGs: COG0496 acid phosphatase; InterPro IPR002828; KEGG: cyt:cce_2598 stationary phase survival protein SurE; PFAM: Survival protein SurE; SPTR: Stationary-phase survival protein; TIGRFAM: stationary-phase survival protein SurE; PFAM: Survival protein SurE; TIGRFAM: 5'/3'-nucleotidase SurE.
    
 0.945
Isop_3422
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.

rpsB
COGs: COG0052 Ribosomal protein S2; InterPro IPR001865: IPR018130: IPR005706; KEGG: psl:Psta_0952 ribosomal protein S2; PFAM: ribosomal protein S2; SPTR: Ribosomal protein S2; TIGRFAM: ribosomal protein S2; PFAM: Ribosomal protein S2; TIGRFAM: ribosomal protein S2, bacterial type; Belongs to the universal ribosomal protein uS2 family.
  
 
 0.929
purK
Phosphoribosylaminoimidazole carboxylase, ATPase subunit; Catalyzes the ATP-dependent conversion of 5-aminoimidazole ribonucleotide (AIR) and HCO(3)(-) to N5-carboxyaminoimidazole ribonucleotide (N5-CAIR).
 
 
 0.923
rplC
LSU ribosomal protein L3P; One of the primary rRNA binding proteins, it binds directly near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit; Belongs to the universal ribosomal protein uL3 family.
