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.

AKB63758.1Queuosine biosynthesis QueD, PTPS-I. (116 aa)    
Predicted Functional Partners:
queE
Queuosine Biosynthesis QueE Radical SAM; Catalyzes the complex heterocyclic radical-mediated conversion of 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) to 7-carboxy-7- deazaguanine (CDG), a step common to the biosynthetic pathways of all 7-deazapurine-containing compounds.
 
 
 0.999
queC
Queuosine Biosynthesis QueC ATPase; Catalyzes the ATP-dependent conversion of 7-carboxy-7- deazaguanine (CDG) to 7-cyano-7-deazaguanine (preQ(0)). Belongs to the QueC family.
 
  
 0.994
AKB63760.1
Hypothetical protein.
 
     0.947
mptA
GTP cyclohydrolase I type 2; Converts GTP to 7,8-dihydro-D-neopterin 2',3'-cyclic phosphate, the first intermediate in the biosynthesis of coenzyme methanopterin.
 
  
 0.932
AKB63934.1
Alkaline phosphatase.
     
  0.900
mptE
6-hydroxymethyl-7,8-dihydropterin pyrophosphokinase; Catalyzes the transfer of diphosphate from ATP to 6- hydroxymethyl-7,8-dihydropterin (6-HMD), leading to 6-hydroxymethyl- 7,8-dihydropterin diphosphate (6-HMDP).
    
 0.831
tgtA
Archaeosine tRNA-ribosyltransferase type 1; Exchanges the guanine residue with 7-cyano-7-deazaguanine (preQ0) at position 15 in the dihydrouridine loop (D-loop) of archaeal tRNAs; Belongs to the archaeosine tRNA-ribosyltransferase family.
 
 
 0.702
cysS
Cysteinyl-tRNA synthetase.
  
  
 0.638
AKB65613.1
Adenosylhomocysteinase; Catalyzes the hydrolysis of S-inosyl-L-homocysteine (SIH) to L-homocysteine (Hcy) and inosine. Likely functions in a S-adenosyl-L- methionine (SAM) recycling pathway from S-adenosyl-L-homocysteine (SAH) produced from SAM-dependent methylation reactions. Can also catalyze the reverse reaction in vitro, i.e. the synthesis of SIH from Hcy and inosine; Belongs to the adenosylhomocysteinase family.
   
 
 0.627
thrS
Threonyl-tRNA synthetase; Belongs to the class-II aminoacyl-tRNA synthetase family.
   
 
 0.532
