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

yggSUPF0001 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. (234 aa)    
Predicted Functional Partners:
yggT
Conserved hypothetical integral membrane protein.

yggU
UPF0235 family protein; Belongs to the UPF0235 family.

rdgB
dITP/XTP pyrophosphatase; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Can also efficiently hydrolyze 2'- deoxy-N-6-hydroxylaminopurine triphosphate (dHAPTP). Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. To a much lesser extent, is als [...]

yggW
HemN family putative oxidoreductase; Probably acts as a heme chaperone, transferring heme to the NarI subunit of the respiratory enzyme nitrate reductase; transfer may be stimulated by NADH. Binds one molecule of heme per monomer, possibly covalently. Heme binding is not affected by either [4Fe-4S] or S- adenosyl-L-methionine (SAM)-binding. Does not have coproporphyrinogen III dehydrogenase activity in vitro. Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine (Probable).

proC
Pyrroline-5-carboxylate reductase, NAD(P)-binding; Catalyzes the reduction of 1-pyrroline-5-carboxylate (PCA) to L-proline. Does not catalyze the reverse reaction.
  
 0.813
yhdE
dTTP/UTP pyrophosphatase; Nucleoside triphosphate pyrophosphatase that hydrolyzes dTTP and UTP. Can also hydrolyze TTP and the modified nucleotides 5-methyl-UTP (m(5)UTP), pseudo-UTP and 5-methyl-CTP (m(5)CTP). Has weak activity with CTP. May have a dual role in cell division arrest and in preventing the incorporation of modified nucleotides into cellular nucleic acids. Important in maintenance of cell shape.

yfiH
UPF0124 family protein; Multicopper oxidase with polyphenol oxidase activity. Is able to oxidize syringaldazine and 2,2'-azino-bis(3-ethylbenzthiazoline-6- sulfonic acid) (ABTS) in vitro. The physiological substrate and role of YfiH is not known.
  
  
 0.714
pdxY
Pyridoxamine 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.
  
  
 0.712
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.

dadX
Alanine racemase, catabolic, PLP-binding; Isomerizes L-alanine to D-alanine which is then oxidized to pyruvate by DadA.
