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

uppUracil phosphoribosyltransferase; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate. (208 aa)    
Predicted Functional Partners:
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 [...]
  
 
 0.997
udk
Uridine/cytidine kinase; Protein involved in nucleobase, nucleoside and nucleotide interconversion; Belongs to the uridine kinase family.
  
 0.997
pyrH
Uridylate kinase; Catalyzes the reversible phosphorylation of UMP to UDP, with ATP as the most efficient phosphate donor.
  
 
 0.988
pyrF
Orotidine-5'-phosphate decarboxylase; Catalyzes the decarboxylation of orotidine 5'-monophosphate (OMP) to uridine 5'-monophosphate (UMP).
  
 
 0.982
deoA
Thymidine phosphorylase; The enzymes which catalyze the reversible phosphorolysis of pyrimidine nucleosides are involved in the degradation of these compounds and in their utilization as carbon and energy sources, or in the rescue of pyrimidine bases for nucleotide synthesis; Belongs to the thymidine/pyrimidine-nucleoside phosphorylase family.
 
 
 0.981
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.
     
 0.969
uraA
Uracil permease; Transport of uracil in the cell. Belongs to the xanthine/uracil permease family. Nucleobase:cation symporter-2 (NCS2) (TC 2.A.40) subfamily.
  
 0.954
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 [...]

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 [...]
    
 0.926
yaiE
UPF0345 family protein; Catalyzes the phosphorolysis of diverse nucleosides, yielding D-ribose 1-phosphate and the respective free bases. Can use uridine, adenosine, guanosine, cytidine, thymidine, inosine and xanthosine as substrates. Also catalyzes the reverse reactions. Is not able to produce D-ribose 1-phosphate from D-ribose and phosphate.
