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

queF7-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
exsB protein; Catalyzes the ATP-dependent conversion of 7-carboxy-7- deazaguanine (CDG) to 7-cyano-7-deazaguanine (preQ(0)).
 
 
 0.988
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.

ADQ03874.1
PFAM: 6-pyruvoyl tetrahydropterin synthase and hypothetical protein; KEGG: ate:Athe_0440 6-pyruvoyl tetrahydropterin synthase and hypothetical protein.

tgt
Queuine tRNA-ribosyltransferase; 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 t [...]

ADQ04010.1
PFAM: GTP cyclohydrolase II; 34-dihydroxy-2-butanone 4-phosphate synthase; KEGG: ate:Athe_0562 3,4-dihydroxy-2-butanone 4-phosphate synthase; In the N-terminal section; belongs to the DHBP synthase family.
     
 0.684
guaA
GMP synthase, large subunit; Catalyzes the synthesis of GMP from XMP.
     
 0.672
ADQ05703.1
KEGG: ate:Athe_2642 transcriptional regulator, AraC family; PFAM: helix-turn-helix- domain containing protein AraC type; SMART: Helix-turn-helix, AraC domain.
       0.527
guaB
Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
     
 0.504
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).
 
  
 0.488
ADQ04012.1
Riboflavin biosynthesis protein RibD; Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'- phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'- phosphate; In the C-terminal section; belongs to the HTP reductase family.
