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.

yfkNExported 2',3'-cyclic-nucleotide 2'-phosphodiesterase, 2' (or 3') nucleotidase and 5' nucleotidase; Catalyzes the release of inorganic phosphate from 2',3'- cyclic nucleotides through consecutive 2',3'-phosphodiesterase and 3'- (or 2') nucleotidase activities. Also possesses a 5'-nucleotidase activity. Does not catalyze the release of inorganic phosphate from 3',5'-cyclic nucleotides. Probably plays a role in the cellular reprocessing of nucleotides present in the medium, under conditions of phosphate shortage. (1462 aa)    
Predicted Functional Partners:
tmk
Thymidylate kinase; Phosphorylation of dTMP to form dTDP in both de novo and salvage pathways of dTTP synthesis; Belongs to the thymidylate kinase family.

ymdB
Putative hydrolase involved in biofilm formation; Plays a central, regulatory role in the late adaptive responses and affects the levels of many genes. May act via regulation of cAMP levels. Decreases the expression of motility genes and induces genes involved in biofilm formation, by controlling the expression of SlrR. Required for formation of intercellular nanotubes that bridge neighboring cells to allow molecular exchange. Plays a key role in directing the early stages of colony development. In vitro, has a metal-dependent phosphodiesterase activity against 2',3'-cAMP and 2',3'-cGM [...]

pupG
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. Cleaves guanosine, inosine, 2'-deoxyguanosine and 2'-deoxyinosine.

tdk
Thymidine kinase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme.
 
  
 0.926
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.
    
 0.925
thyB
Thymidylate synthase B; 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.

hprT
Hypoxanthine-guanine phosphoribosyltransferase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme.
  
  
 0.923
guaB
Inosine-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth.
   
 0.922
guaC
GMP reductase; Catalyzes the irreversible NADPH-dependent deamination of GMP to IMP. It functions in the conversion of nucleobase, nucleoside and nucleotide derivatives of G to A nucleotides, and in maintaining the intracellular balance of A and G nucleotides (Probable).
   
 0.921
deoD
Purine nucleoside phosphorylase; Cleavage of adenosine and its derivatives; Belongs to the PNP/UDP phosphorylase family.
