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

queFNADPH-dependent 7-cyano-7-deazaguanine reductase; Catalyzes the NADPH-dependent reduction of 7-cyano-7- deazaguanine (preQ0) to 7-aminomethyl-7-deazaguanine (preQ1). Belongs to the GTP cyclohydrolase I family. QueF type 1 subfamily. (131 aa)    
Predicted Functional Partners:
queC
preQ(0) biosynthesis protein QueC; Catalyzes the ATP-dependent conversion of 7-carboxy-7- deazaguanine (CDG) to 7-cyano-7-deazaguanine (preQ(0)). Belongs to the QueC family.
 
 
 0.989
queE
Radical SAM domain protein; 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.

AFY71192.1
Queuosine biosynthesis protein QueD; PFAM: 6-pyruvoyl tetrahydropterin synthase; TIGRFAM: queuosine biosynthesis protein QueD; 6-pyruvoyl tetrahydropterin synthase/QueD family protein; COGs: COG0720 6-pyruvoyl-tetrahydropterin synthase; InterPro IPR007115; KEGG: cyj:Cyan7822_1992 6-pyruvoyl tetrahydropterin synthase/hypothetical protein; PFAM: 6-pyruvoyl tetrahydropterin synthase-related; SPTR: Putative uncharacterized protein; TIGRFAM: queuosine biosynthesis protein QueD.

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 [...]
