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 kinase (udk); Similar to SP:P31218 GB:X71492 PID:296947 GB:U00096 PID:1736770 percent identity: 67.82; identified by sequence similarity; putative. (213 aa)    
Predicted Functional Partners:
serA
D-3-phosphoglycerate dehydrogenase (serA); Catalyzes the reversible oxidation of 3-phospho-D-glycerate to 3-phosphonooxypyruvate, the first step of the phosphorylated L- serine biosynthesis pathway. Also catalyzes the reversible oxidation of 2-hydroxyglutarate to 2-oxoglutarate.

rapA
ATP-dependent helicase (hepA); Transcription regulator that activates transcription by stimulating RNA polymerase (RNAP) recycling in case of stress conditions such as supercoiled DNA or high salt concentrations. Probably acts by releasing the RNAP, when it is trapped or immobilized on tightly supercoiled DNA. Does not activate transcription on linear DNA. Probably not involved in DNA repair; Belongs to the SNF2/RAD54 helicase family. RapA subfamily.
    
  0.986
kdkA
Predicted coding region HI0260.1; Catalyzes the ATP-dependent phosphorylation of the 3-deoxy-D- manno-octulosonic acid (Kdo) residue in Kdo-lipid IV(A) at the 4-OH position. To a lesser extent, can use GTP instead of ATP as substrate.
    
 0.940
upp
Uracil phosphoribosyltransferase (upp); Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate.
  
 0.911
gapA
Glyceraldehyde-3-phosphate dehydrogenase (gapdH); Catalyzes the oxidative phosphorylation of glyceraldehyde 3- phosphate (G3P) to 1,3-bisphosphoglycerate (BPG) using the cofactor NAD. The first reaction step involves the formation of a hemiacetal intermediate between G3P and a cysteine residue, and this hemiacetal intermediate is then oxidized to a thioester, with concomitant reduction of NAD to NADH. The reduced NADH is then exchanged with the second NAD, and the thioester is attacked by a nucleophilic inorganic phosphate to produce BPG.
   
 0.887
cdd
Cytidine deaminase (cdd); This enzyme scavenges exogenous and endogenous cytidine and 2'-deoxycytidine for UMP synthesis.
    
 0.883
dnaJ
Heat shock protein (dnaJ); Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP-dependent interactions between DnaJ [...]
   
 0.848
udp
Uridine phosphorylase (udp); 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 (By similarity).
    
 0.810
HI_0134
Predicted coding region HI0134; Hypothetical protein; identified by GeneMark; putative.
       0.788
dcd
Deoxycytidine triphosphate deaminase (dcd); Catalyzes the deamination of dCTP to dUTP.
