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

pdxYPyridoxamine kinase; Pyridoxal kinase involved in the salvage pathway of pyridoxal 5'-phosphate (PLP). Catalyzes the phosphorylation of pyridoxal to PLP in vivo, but shows very low activity compared to PdxK. Displays a low level of pyridoxine kinase activity when overexpressed, which is however not physiologically relevant. (287 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).
  
 
 0.994
ydbC
Putative NAD(P)-binding oxidoreductase; Catalyzes the NAD(P)H-dependent reduction of pyridoxal to pyridoxine in vitro. Is not able to reduce 4-pyridoxate, and to oxidize pyridoxine or pyridoxamine. Has Kemp eliminase activity towards the non-physiological substrate 5-nitrobenzisoxazole, producing 4-nitro-2-cyanophenol; this activity is not considered to be physiologically relevant. Belongs to the aldo/keto reductase family. Aldo/keto reductase 2 subfamily.
     
 0.977
pdxJ
Pyridoxine 5'-phosphate synthase; 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.
     
 0.950
pdxK
Pyridoxal-pyridoxamine kinase/hydroxymethylpyrimidine 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.
  
  
0.944
yggS
UPF0001 family protein, PLP-binding; Pyridoxal 5'-phosphate (PLP)-binding protein, which is involved in PLP homeostasis. May have a carrier function to deliver PLP to the target enzymes or a protective function so that PLP does not inactivate essential lysines in proteins. Does not have amino acid racemase activity.
  
  
 0.712
tyrS
tyrosyl-tRNA synthetase; Catalyzes the attachment of L-tyrosine to tRNA(Tyr) in a two- step reaction: tyrosine is first activated by ATP to form Tyr-AMP and then transferred to the acceptor end of tRNA(Tyr). Can also mischarge tRNA(Tyr) with D-tyrosine, leading to the formation of D-tyrosyl-tRNA(Tyr), which can be hydrolyzed by the D-aminoacyl-tRNA deacylase. In vitro, can also use the non-natural amino acid azatyrosine.
  
  
 0.691
ybhA
Pyridoxal phosphate (PLP) phosphatase; Catalyzes the dephosphorylation of pyridoxal-phosphate (PLP). Can also hydrolyze erythrose-4-phosphate (Ery4P) and fructose-1,6-bis- phosphate (Fru1,6bisP); Belongs to the HAD-like hydrolase superfamily. CbbY/CbbZ/Gph/YieH family.
  
  
 0.648
serC
3-phosphoserine/phosphohydroxythreonine aminotransferase; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine. Is involved in both pyridoxine and serine biosynthesis; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. SerC subfamily.
