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

udkUridine/cytidine kinase; Protein involved in nucleobase, nucleoside and nucleotide interconversion; Belongs to the uridine kinase family. (213 aa)    
Predicted Functional Partners:
upp
Uracil phosphoribosyltransferase; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate.
  
 0.997
udp
Uridine phosphorylase; Catalyzes the reversible phosphorylytic cleavage of uridine and deoxyuridine to uracil and ribose- or deoxyribose-1-phosphate. The produced molecules are then utilized as carbon and energy sources or in the rescue of pyrimidine bases for nucleotide synthesis.
  
 
 0.985
cmk
Cytidylate kinase; ATP, dATP, and GTP are equally effective as phosphate donors. CMP and dCMP are the best phosphate acceptors. Belongs to the cytidylate kinase family. Type 1 subfamily.
   
 
 0.983
cdd
Cytidine/deoxycytidine deaminase; This enzyme scavenges exogenous and endogenous cytidine and 2'-deoxycytidine for UMP synthesis.
    
 0.980
pyrH
Uridylate kinase; Catalyzes the reversible phosphorylation of UMP to UDP, with ATP as the most efficient phosphate donor.
   
 
 0.969
umpG
Broad specificity 5'(3')-nucleotidase and polyphosphatase; Nucleotidase with a broad substrate specificity as it can dephosphorylate various ribo- and deoxyribonucleoside 5'-monophosphates and ribonucleoside 3'-monophosphates with highest affinity to 3'-AMP. Also hydrolyzes polyphosphate (exopolyphosphatase activity) with the preference for short-chain-length substrates (P20-25). Might be involved in the regulation of dNTP and NTP pools, and in the turnover of 3'-mononucleotides produced by numerous intracellular RNases (T1, T2, and F) during the degradation of various RNAs. Also plays [...]
   
 
 0.961
ushA
Bifunctional UDP-sugar hydrolase/5'-nucleotidase; Degradation of external UDP-glucose to uridine monophosphate and glucose-1-phosphate, which can then be used by the cell.
 
 
 0.953
rihB
Ribonucleoside 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.
   
 0.950
pyrF
Orotidine-5'-phosphate decarboxylase; Catalyzes the decarboxylation of orotidine 5'-monophosphate (OMP) to uridine 5'-monophosphate (UMP).
  
 0.949
yjjG
dUMP phosphatase; Nucleotidase that shows high phosphatase activity toward non- canonical pyrimidine nucleotides and three canonical nucleoside 5'- monophosphates (UMP, dUMP, and dTMP), and very low activity against TDP, IMP, UDP, GMP, dGMP, AMP, dAMP, and 6-phosphogluconate. Appears to function as a house-cleaning nucleotidase in vivo, since the general nucleotidase activity of YjjG allows it to protect cells against non- canonical pyrimidine derivatives such as 5-fluoro-2'-deoxyuridine, 5- fluorouridine, 5-fluoroorotate, 5-fluorouracil, and 5-aza-2'- deoxycytidine, and prevents the i [...]
