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

pdxKPyridoxal-pyridoxamine kinase; B6-vitamer kinase involved in the salvage pathway of pyridoxal 5'-phosphate (PLP). Catalyzes the phosphorylation of pyridoxine (PN), pyridoxal (PL), and pyridoxamine (PM), forming their respective 5'-phosphorylated esters, i.e. PNP, PLP and PMP. Belongs to the pyridoxine kinase family. PdxK subfamily. (288 aa)    
Predicted Functional Partners:
pdxH
Pyridoxine 5'-phosphate oxidase; Catalyzes the oxidation of either pyridoxine 5'-phosphate (PNP) or pyridoxamine 5'-phosphate (PMP) into pyridoxal 5'-phosphate (PLP).
   
 
 0.973
pdxJ
Carries out condensation and ring closure step after PdxA in pyridoxine biosynthesis; Catalyzes the complicated ring closure reaction between the two acyclic compounds 1-deoxy-D-xylulose-5-phosphate (DXP) and 3-amino- 2-oxopropyl phosphate (1-amino-acetone-3-phosphate or AAP) to form pyridoxine 5'-phosphate (PNP) and inorganic phosphate.
   
 
 0.955
ptsJ
Putative gntR family regulatory protein; Acts as transcriptional repressor of the pdxK gene, encoding a pyridoxal kinase involved in the vitamin B6 salvage pathway. Also represses transcription of its own gene. Binds to the ptsJ-pdxK intergenic region, but does not bind pdxY and pdxH promoters. Among all six B6 vitamers, only pyridoxal 5'-phosphate (PLP) clearly binds to the protein and acts as an effector molecule for PtsJ, inducing a protein conformational change that increases affinity for DNA. Thus, PLP stabilizes protein-DNA interactions, reinforcing repression. In the C-terminal [...]

pdxY
Pyridoxal kinase 2; Pyridoxal kinase involved in the salvage pathway of pyridoxal 5'-phosphate (PLP). Catalyzes the phosphorylation of pyridoxal to PLP.
  
  
0.947
thiD
Hydroxy-phosphomethylpyrimidine kinase (HMP-P kinase); Catalyzes the phosphorylation of hydroxymethylpyrimidine phosphate (HMP-P) to HMP-PP, and of HMP to HMP-P. Belongs to the ThiD family.
  
 
 0.912
STM2434
Putative cytoplasmic protein.
       0.797
ybhA
Putative hydrolase of the HAD superfamily; Similar to E. coli putative phosphatase (AAC73853.1); Blastp hit to AAC73853.1 (272 aa), 84% identity in aa 1 - 272.
     
 0.771
epd
D-erythrose 4-phosphate dehydrogenase; Catalyzes the NAD-dependent conversion of D-erythrose 4- phosphate to 4-phosphoerythronate.
   
  
 0.677
yfeJ
Putative GMP synthase; Contains glutamine amidotransferase domain; hypothetical 18.7 Kda protein in pdxK-cysM intergenic region. (SW:YFEJ_SALTY).
  
    0.585
ymdC
Putative phospholipase; Catalyzes the synthesis of cardiolipin (CL) (diphosphatidylglycerol) from phosphatidylglycerol (PG) and phosphatidylethanolamine (PE); Belongs to the phospholipase D family. Cardiolipin synthase subfamily. ClsC sub-subfamily.
