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

tgttRNA-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 [...] (427 aa)    
Predicted Functional Partners:
mmpL2
Putative RND superfamily drug exporter; PFAM: MMPL family.
      0.863
gluQ
tRNA synthetases class I (E and Q), catalytic domain; Catalyzes the tRNA-independent activation of glutamate in presence of ATP and the subsequent transfer of glutamate onto a tRNA(Asp). Glutamate is transferred on the 2-amino-5-(4,5-dihydroxy-2- cyclopenten-1-yl) moiety of the queuosine in the wobble position of the QUC anticodon; Belongs to the class-I aminoacyl-tRNA synthetase family. GluQ subfamily.
 
   
 0.817
AJI77738.1
Conserved hypothetical integral membrane protein; Involved in the import of queuosine (Q) precursors, required for Q precursor salvage; Belongs to the vitamin uptake transporter (VUT/ECF) (TC 2.A.88) family. Q precursor transporter subfamily.
 
   
 0.761
guaA
GMP synthase (glutamine-hydrolyzing); Catalyzes the synthesis of GMP from XMP.
  
  
 0.621
AJI77730.1
PFAM: CsbD-like; Belongs to the UPF0337 (CsbD) family.
 
     0.547
fkb
PFAM: FKBP-type peptidyl-prolyl cis-trans isomerase.
    
  0.478
AJI77732.1
PFAM: Major Facilitator Superfamily.
       0.449
ribBA
GTP cyclohydrolase II /3,4-dihydroxy-2-butanone 4-phosphate synthase; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; In the C-terminal section; belongs to the GTP cyclohydrolase II family.
     
 0.448
aspS
aspartyl-tRNA synthetase; Aspartyl-tRNA synthetase with relaxed tRNA specificity since it is able to aspartylate not only its cognate tRNA(Asp) but also tRNA(Asn). Reaction proceeds in two steps: L-aspartate is first activated by ATP to form Asp-AMP and then transferred to the acceptor end of tRNA(Asp/Asn); Belongs to the class-II aminoacyl-tRNA synthetase family. Type 1 subfamily.
 
    0.443
AJI78850.1
tRNA/rRNA cytosine-C5-methylase; PFAM: NOL1/NOP2/sun family; NusB family; TIGRFAM: 16S rRNA (cytosine(967)-C(5))-methyltransferase; Belongs to the class I-like SAM-binding methyltransferase superfamily. RsmB/NOP family.
