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

Score
surEsurE stationary-phase survival protein SurE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family. (276 aa)    
Predicted Functional Partners:
guaB
Inosine-5'-monophosphate dehydrogenase, (guaB); 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.
    
 0.983
purA
Adenylosuccinate synthetase (purA); 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.
    
 0.972
guaAB
GMP synthase (guaA); Catalyzes the synthesis of GMP from XMP.
    
 0.958
guaAA
GMP synthase (guaA); Catalyzes the synthesis of GMP from XMP.
    
 0.957
pyrH
Uridylate kinase (pyrH); Catalyzes the reversible phosphorylation of UMP to UDP.
    
 0.953
tmk
Thymidylate kinase (tmk); Similar to SP:P36590 percent identity: 31.18; identified by sequence similarity; putative.
 
  
 0.950
hpt
Adenine phosphoribosyltransferase (apt); Catalyzes a salvage reaction resulting in the formation of IMP that is energically less costly than de novo synthesis. Belongs to the purine/pyrimidine phosphoribosyltransferase family. Archaeal HPRT subfamily.
    
 0.948
purB
Adenylosuccinate lyase (purB); Similar to GB:J02732 SP:P12047 PID:143366 GB:AL009126 percent identity: 42.51; identified by sequence similarity; putative.
    
 0.933
pyrF
Conserved hypothetical protein; Catalyzes the decarboxylation of orotidine 5'-monophosphate (OMP) to uridine 5'-monophosphate (UMP); Belongs to the OMP decarboxylase family. Type 1 subfamily.
    
 0.927
thyA
Thymidylate synthase (thyA); May catalyze the biosynthesis of dTMP using an unknown cosubstrate; Belongs to the thymidylate synthase family. Archaeal-type ThyA subfamily.
