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

mqnAProtein of unknown function DUF178; Catalyzes the dehydration of chorismate into 3-[(1- carboxyvinyl)oxy]benzoate, a step in the biosynthesis of menaquinone (MK, vitamin K2). (283 aa)    
Predicted Functional Partners:
mqnE
Radical SAM domain protein; Radical SAM enzyme that catalyzes the addition of the adenosyl radical to the double bond of 3-[(1-carboxyvinyl)oxy]benzoate, leading to aminodeoxyfutalosine (AFL), a key intermediate in the formation of menaquinone (MK, vitamin K2) from chorismate.
  
 0.987
mqnD
Protein of unknown function DUF191; Catalyzes the conversion of cyclic dehypoxanthine futalosine (cyclic DHFL) into 1,4-dihydroxy-6-naphthoate, a step in the biosynthesis of menaquinone (MK, vitamin K2); Belongs to the MqnA/MqnD family. MqnD subfamily.
 
   
 0.917
mqnB
Nucleoside phosphorylase-like protein; Catalyzes the hydrolysis of futalosine (FL) to dehypoxanthine futalosine (DHFL) and hypoxanthine, a step in the biosynthesis of menaquinone (MK, vitamin K2).
  
   
 0.906
mqnC
Radical SAM domain protein; Radical SAM enzyme that catalyzes the cyclization of dehypoxanthine futalosine (DHFL) into cyclic dehypoxanthine futalosine (CDHFL), a step in the biosynthesis of menaquinone (MK, vitamin K2).

Sare_4513
TIGRFAM: 4-hydroxybenzoate polyprenyltransferase, putative; PFAM: UbiA prenyltransferase; KEGG: stp:Strop_4093 4-hydroxybenzoate polyprenyltransferase, putative; Belongs to the UbiA prenyltransferase family.
 
   
 0.854
Sare_4208
TIGRFAM: chorismate mutase; PFAM: Chorismate mutase; KEGG: stp:Strop_3818 chorismate mutase.

Sare_4512
TIGRFAM: 3-octaprenyl-4-hydroxybenzoate carboxy-lyase; PFAM: flavoprotein; KEGG: stp:Strop_4092 3-octaprenyl-4-hydroxybenzoate carboxy-lyase.

aroC
Chorismate synthase; Catalyzes the anti-1,4-elimination of the C-3 phosphate and the C-6 proR hydrogen from 5-enolpyruvylshikimate-3-phosphate (EPSP) to yield chorismate, which is the branch point compound that serves as the starting substrate for the three terminal pathways of aromatic amino acid biosynthesis. This reaction introduces a second double bond into the aromatic ring system.
    
  0.816
trpE
Anthranilate synthase component I; Part of a heterotetrameric complex that catalyzes the two- step biosynthesis of anthranilate, an intermediate in the biosynthesis of L-tryptophan. In the first step, the glutamine-binding beta subunit (TrpG) of anthranilate synthase (AS) provides the glutamine amidotransferase activity which generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by the large alpha subunit of AS (TrpE) to produce anthranilate. In the absence of TrpG, TrpE can synthesize anthranilate directly from chorismate and high concentr [...]

hisC
TIGRFAM: histidinol-phosphate aminotransferase; PFAM: aminotransferase class I and II; KEGG: stp:Strop_3195 histidinol-phosphate aminotransferase; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. Histidinol-phosphate aminotransferase subfamily.
