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.

pdxA2Pyridoxine phosphate biosynthetic protein; Catalyzes the NAD-dependent oxidation and subsequent decarboxylation of D-threonate 4-phosphate to produce dihydroxyacetone phosphate (DHAP). Can also use 4-hydroxy-L-threonine 4-phosphate as substrate. Belongs to the PdxA family. PdxA2 subfamily. (327 aa)    
Predicted Functional Partners:
dtnK
Putative inner membrane protein; Catalyzes the ATP-dependent phosphorylation of D-threonate to D-threonate 4-phosphate. Can also phosphorylate 4- hydroxy-L-threonine, with lower efficiency. This side reaction may serve to deal with the toxicity of 4-hydroxy-L-threonine by converting it into 4-hydroxy-L-threonine 4-phosphate, a useful product that can be used by PdxA2. Belongs to the four-carbon acid sugar kinase family.
     0.991
kdgT
2-keto-3-deoxygluconate permease; The 2-keto-3-deoxygluconate permease transports the degraded pectin products into the bacterial cell, where they serve as carbon and energy sources. This is a hydrogen coupled transport system (By similarity); Belongs to the KdgT transporter family.
 
    0.935
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.

STM0164
Similar to E. coli putative DEOR-type transcriptional regulator (AAC75777.1); Blastp hit to AAC75777.1 (265 aa), 34% identity in aa 16 - 265.
  
    0.799
kdgT2
Putative permease; The 2-keto-3-deoxygluconate permease transports the degraded pectin products into the bacterial cell, where they serve as carbon and energy sources. This is a hydrogen coupled transport system (By similarity); Belongs to the KdgT transporter family.
 
     0.728
yacL
Putative cytoplasmic protein; Similar to E. coli orf, hypothetical protein (AAC73230.1); Blastp hit to AAC73230.1 (136 aa), 85% identity in aa 17 - 135; Belongs to the UPF0231 family.
 
    0.501
folA
Dihydrofolate reductase type I; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis.
    
 0.459
pdxB
Erythronate-4-phosphate dehydrogenase; Catalyzes the oxidation of erythronate-4-phosphate to 3- hydroxy-2-oxo-4-phosphonooxybutanoate.
 
   
 0.450
folC
Folylpolyglutamate synthase; Functions in two distinct reactions of the de novo folate biosynthetic pathway. Catalyzes the addition of a glutamate residue to dihydropteroate (7,8-dihydropteroate or H2Pte) to form dihydrofolate (7,8-dihydrofolate monoglutamate or H2Pte-Glu). Also catalyzes successive additions of L-glutamate to tetrahydrofolate or 10- formyltetrahydrofolate or 5,10-methylenetetrahydrofolate, leading to folylpolyglutamate derivatives.
 
   
 0.431
ygbK
Putative tRNA synthase; Catalyzes the ATP-dependent phosphorylation of 3-oxo- tetronate to 3-oxo-tetronate 4-phosphate. Belongs to the four-carbon acid sugar kinase family.
