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

tdkHypothetical protein; KEGG: sfx:S1324 2.0e-101 tdk; thymidine kinase K00857; COG: COG1435 Thymidine kinase. (205 aa)    
Predicted Functional Partners:
dut
Hypothetical protein; This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA; Belongs to the dUTPase family.
   
 
 0.986
thyA
Hypothetical protein; Catalyzes the reductive methylation of 2'-deoxyuridine-5'- monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor and reductant in the reaction, yielding dihydrofolate (DHF) as a by- product. This enzymatic reaction provides an intracellular de novo source of dTMP, an essential precursor for DNA biosynthesis.
  
 
 0.979
tmk
Hypothetical protein; Phosphorylation of dTMP to form dTDP in both de novo and salvage pathways of dTTP synthesis; Belongs to the thymidylate kinase family.
 
 
 0.950
deoA
Hypothetical protein; 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.
 
  
 0.948
deoD
Hypothetical protein; KEGG: sty:STY4921 3.0e-123 deoD, pup; purine nucleoside phosphorylase K03784; COG: COG0813 Purine-nucleoside phosphorylase; Psort location: Cytoplasmic, score:8.96.
  
 
 0.938
cdd
Hypothetical protein; This enzyme scavenges exogenous and endogenous cytidine and 2'-deoxycytidine for UMP synthesis.
    
 0.933
CKO_02669
Hypothetical protein; KEGG: sec:SC0536 3.0e-281 ushA; UDP-sugar hydrolase 5'-nucleotidase K01081:K08077; COG: COG0737 5-nucleotidase/2,3-cyclic phosphodiesterase and related esterases; Psort location: Periplasmic, score:10.00; Belongs to the 5'-nucleotidase family.
 
  
  0.931
CKO_00118
Hypothetical protein; KEGG: sty:STY3644 6.3e-107 probable uridine phosphorylase K00757; COG: COG2820 Uridine phosphorylase; Psort location: Cytoplasmic, score:8.96.
     
 0.920
CKO_00173
Hypothetical protein; 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. Belongs to the PNP/UDP phosphorylase family.

CKO_03418
Hypothetical protein; KEGG: spt:SPA4373 3.0e-107 yjjG; hypothetical protein K08723; COG: COG1011 Predicted hydrolase (HAD superfamily).
