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

udpAUridine 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; Forms a homohexamer; Localized in the cytoplasm; High confidence in function and specificity. (290 aa)    
Predicted Functional Partners:
cdd
Cytidine deaminase; This enzyme scavenges exogenous and endogenous cytidine and 2'-deoxycytidine for UMP synthesis; Belongs to the cytidine and deoxycytidylate deaminase family.
 
 
 0.982
uppA
Uracil phosphoribosyltransferase is involved in pyrimidine metabolism. In presence of diphosphate, it converts UMP to uracyl and 5-phospho-alpha-D-ribose 1-diphosphate (PRPP); Uses magnesium ion as a cofactor; Localized in the cytoplasm; High confidence in function and specificity.
  
  
 0.933
punA
Purine nucleoside phosphorylase; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate.
    
 0.924
udk
Uridine kinase (pyrimidine ribonucleoside kinase) is the rate-limiting enzyme in the pyrimidine salvage pathway. It catalyzes the reactions: ATP + uridine = ADP + UMP and ATP + cytidine = ADP + CMP. It forms a homotetramer and binds a ATP per subunit as cofactor. Localized in the cytoplasm; High confidence in function and specificity.
    
 0.919
tdkA
Thymidine kinase is an ubiquitous enzyme that catalyzes the ATP-dependent phosphorylation of thymidine; Localized in the cytoplasm; High confidence in function and specificity.
     
 0.915
surE
Stationary-phase survival protein surE; Nucleotidase that shows phosphatase activity on nucleoside 5'-monophosphates; Belongs to the SurE nucleotidase family.
     
 0.907
pyrR2
Bifunctional protein PyrR; PyrR regulates transcriptional attenuation of the pyrimidine nucleotide operon by binding in a uridine-dependent manner to specific sites on pyr mRNA. This disrupts an antiterminator hairpin in the RNA and favors formation of a downstream transcription terminator, leading to a reduced expression of downstream genes. Also displays a weak uracil phosphoribosyltransferase activity which is not physiologically significant. Forms momodimer and homohexamer in equilibrium. Localized in the cytoplasm; High confidence in function and specificity.
    
 0.903
pyrR1
Bifunctional protein pyrR; PyrR regulates transcriptional attenuation of the pyrimidine nucleotide (pyr) operon by binding in a uridine-dependent manner to specific sites on pyr mRNA. This disrupts an antiterminator hairpin in the RNA and favors formation of a downstream transcription terminator, leading to a reduced expression of downstream genes. Also displays a weak uracil phosphoribosyltransferase activity which is not physiologically significant. It forms in equilibrium a homodimer and a homohexamer. Localized in the cytoplasm; High confidence in function and specificity.
    
 0.903
nutA
5'-Nucleotidase, phosphatase subunit; The 5'-Nucleotidase is involved in the degradation of extracellular 5'-nucleotides into membrane permeable nucleosides. Usually It is composed of a N-terminal phosphatase domain that provides the ligands to the dimetal cluster and a conserved histidine, which together form the catalytic site and of a C-terminal domain involved in the substrate binding; This lipoprotein corresponds only to the phosphatase domain that hydrolyses the phosphate esterified at carbon 5' of the ribose and deoxyribose portions of nucleotide molecules; Binds a chloride ion [...]

CAZ98530.1
Conserved hypothetical protein; Localized in the cytoplasm.
