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

mqnD1,4-dihydroxy-6-naphthoate synthase; 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. (282 aa)    
Predicted Functional Partners:
mqnB
Futalosine nucleosidase; Catalyzes the hydrolysis of futalosine (FL) to dehypoxanthine futalosine (DHFL) and hypoxanthine, a step in the biosynthesis of menaquinone (MK, vitamin K2).
 
  
 0.998
mqnC
Hypothetical 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).
 
  
 0.996
mqnA
Menaquinone biosynthesis protein; Catalyzes the dehydration of chorismate into 3-[(1- carboxyvinyl)oxy]benzoate, a step in the biosynthesis of menaquinone (MK, vitamin K2).
 
  
 0.974
mqnE
Radical SAM 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.
 
  
 0.938
fbiC
FO synthase; 7,8-didemethyl-8-hydroxy-5-deazariboflavin synthase; catalyzes radical-mediated transfer of hydroxybenzyl group from 4-hydroxyphenylpyruvate (HPP) to 5-amino-6-ribitylamino-2,4(1H,3H)-pyrimidinedione to form 7,8-didemethyl-8-hydroxy-5-deazariboflavin (FO); functions in F420 biosynthesis.
 
  
 0.892
ubiA
UbiA prenyltransferase family catalyzes the transfer of a prenyl group to various acceptors with hydrophobic ring structures in the biosynthesis of respiratory quinones, hemes, chlorophylls, vitamin E, and shikonin.
 
   
 0.875
AKJ11466.1
2-oxoglutarate ferredoxin oxidoreductase subunit alpha.
  
  
  0.828
AKJ12427.1
Lipoprotein.
       0.812
AKJ11538.1
Hypothetical protein; Belongs to the UbiD family.
  
   
 0.808
ubiX
Aromatic acid decarboxylase; Flavin prenyltransferase that catalyzes the synthesis of the prenylated FMN cofactor (prenyl-FMN) for 4-hydroxy-3-polyprenylbenzoic acid decarboxylase UbiD. The prenyltransferase is metal-independent and links a dimethylallyl moiety from dimethylallyl monophosphate (DMAP) to the flavin N5 and C6 atoms of FMN; Belongs to the UbiX/PAD1 family.
