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

queD6-carboxy-5,6,7,8-tetrahydropterin synthase; Catalyzes the conversion of 7,8-dihydroneopterin triphosphate (H2NTP) to 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) and acetaldehyde. Belongs to the PTPS family. QueD subfamily. (149 aa)    
Predicted Functional Partners:
queC
Pre-queuosine 0 synthase; Catalyzes the ATP-dependent conversion of 7-carboxy-7- deazaguanine (CDG) to 7-cyano-7-deazaguanine (preQ(0)). Uses ammonia as nitrogen donor.
 
  
 0.999
queE
7-carboxy-7-deazaguanine synthase; 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
queF
NADPH-dependent 7-cyano-7-deazaguanine reductase; Catalyzes the NADPH-dependent reduction of 7-cyano-7- deazaguanine (preQ0) to 7-aminomethyl-7-deazaguanine (preQ1), a late step in the queuosine pathway; Belongs to the GTP cyclohydrolase I family. QueF type 1 subfamily.
 
  
 0.998
folEA
GTP cyclohydrolase I; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the GTP cyclohydrolase I family.
  
 
 0.998
folEB
GTP cyclohydrolase I; Converts GTP to 7,8-dihydroneopterin triphosphate. Belongs to the GTP cyclohydrolase IV family.
    
 0.944
tgt
tRNA-guanine transglycosylase; Catalyzes the base-exchange of a guanine (G) residue with the queuine precursor 7-aminomethyl-7-deazaguanine (PreQ1) at position 34 (anticodon wobble position) in tRNAs with GU(N) anticodons (tRNA-Asp, -Asn, -His and -Tyr). Catalysis occurs through a double-displacement mechanism. The nucleophile active site attacks the C1' of nucleotide 34 to detach the guanine base from the RNA, forming a covalent enzyme-RNA intermediate. The proton acceptor active site deprotonates the incoming PreQ1, allowing a nucleophilic attack on the C1' of the ribose to form the [...]

queA
S-adenosylmethionine tRNA ribosyltransferase-isomerase; Transfers and isomerizes the ribose moiety from AdoMet to the 7-aminomethyl group of 7-deazaguanine (preQ1-tRNA) to give epoxyqueuosine (oQ-tRNA).
     
 0.934
queG
Epoxyqueuosine reductase; Catalyzes the conversion of epoxyqueuosine (oQ) to queuosine (Q), which is a hypermodified base found in the wobble positions of tRNA(Asp), tRNA(Asn), tRNA(His) and tRNA(Tyr).
  
  
 0.933
