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

rihBRibonucleoside hydrolase 2; Hydrolyzes cytidine or uridine to ribose and cytosine or uracil, respectively. Has a clear preference for cytidine over uridine. Strictly specific for ribonucleosides. Has a low but significant activity for the purine nucleoside xanthosine; Belongs to the IUNH family. RihB subfamily. (313 aa)    
Predicted Functional Partners:
cdd
Cytidine/deoxycytidine deaminase; This enzyme scavenges exogenous and endogenous cytidine and 2'-deoxycytidine for UMP synthesis.
   
 0.959
udk
Uridine/cytidine kinase; Protein involved in nucleobase, nucleoside and nucleotide interconversion; Belongs to the uridine kinase family.
   
 0.950
codA
Cytosine/isoguanine deaminase; Catalyzes the hydrolytic deamination of cytosine to uracil. Is involved in the pyrimidine salvage pathway, which allows the cell to utilize cytosine for pyrimidine nucleotide synthesis. Is also able to catalyze deamination of isoguanine, a mutagenic oxidation product of adenine in DNA, and of isocytosine. To a lesser extent, also catalyzes the conversion of 5-fluorocytosine (5FC) to 5-fluorouracil (5FU); this activity allows the formation of a cytotoxic chemotherapeutic agent from a non-cytotoxic precursor. Belongs to the metallo-dependent hydrolases supe [...]
  
 
 0.919
guaD
Guanine deaminase; Catalyzes the hydrolytic deamination of guanine, producing xanthine and ammonia; Belongs to the metallo-dependent hydrolases superfamily. ATZ/TRZ family.
 
 
 0.914
deoD
Purine nucleoside phosphorylase 1; Cleavage of guanosine or inosine to respective bases and sugar-1-phosphate molecules.
     
 0.911
add
Adenosine deaminase; Protein involved in nucleobase, nucleoside and nucleotide interconversion; Belongs to the metallo-dependent hydrolases superfamily. Adenosine and AMP deaminases family. Adenosine deaminase subfamily.
 
 
 0.910
hpt
Hypoxanthine phosphoribosyltransferase; Acts preferentially on hypoxanthine; has very low activity towards guanine. Inactive towards xanthine. Belongs to the purine/pyrimidine phosphoribosyltransferase family.
     
 0.909
cpdB
2':3'-cyclic-nucleotide 2'-phosphodiesterase; This bifunctional enzyme catalyzes two consecutive reactions during ribonucleic acid degradation. Converts a 2',3'-cyclic nucleotide to a 3'-nucleotide and then the 3'-nucleotide to the corresponding nucleoside and phosphate; Belongs to the 5'-nucleotidase family.
  
 
  0.909
gpt
Xanthine phosphoribosyltransferase; Acts on guanine, xanthine and to a lesser extent hypoxanthine.
     
 0.906
apt
Adenine phosphoribosyltransferase; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis.
     
 0.906
