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

pdxHPyridoxine 5'-phosphate oxidase; Catalyzes the oxidation of either pyridoxine 5'-phosphate (PNP) or pyridoxamine 5'-phosphate (PMP) into pyridoxal 5'-phosphate (PLP). (218 aa)    
Predicted Functional Partners:
pdxY
Pyridoxal kinase 2; Pyridoxal kinase involved in the salvage pathway of pyridoxal 5'-phosphate (PLP). Catalyzes the phosphorylation of pyridoxal to PLP.
  
 
 0.996
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.
  
 
 0.989
pdxK
Pyridoxal-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.
   
 
 0.973
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 [...]
     
 0.901
pdxA
NAD-dependent dehydrogenase/carboxylase; Catalyzes the NAD(P)-dependent oxidation of 4-(phosphooxy)-L- threonine (HTP) into 2-amino-3-oxo-4-(phosphooxy)butyric acid which spontaneously decarboxylates to form 3-amino-2-oxopropyl phosphate (AHAP).
      
 0.863
pyrB
Aspartate carbamoyltransferase catalytic chain. (SW:PYRB_SALTY).
 
    0.856
yggS
Putative enzyme with a TIM-barrel fold; Pyridoxal 5'-phosphate (PLP)-binding protein, which is involved in PLP homeostasis.
      
 0.809
yjbQ
Putative cytoplasmic protein; Similar to E. coli orf, hypothetical protein (AAC77026.1); Blastp hit to AAC77026.1 (138 aa), 78% identity in aa 1 - 138; Belongs to the UPF0047 family.
     
 0.783
serC
3-phosphoserine aminotransferase; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. SerC subfamily.
  
  
 0.764
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.
