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

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 [...] (332 aa)    
Predicted Functional Partners:
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).
 
 0.996
NSP_51420
FKBP-type peptidyl-prolyl cis-trans isomerase; Nsp51420; ORF_ID:nsp51420.
    
  0.895
guaA
GMP synthase [glutamine-hydrolyzing]; Catalyzes the synthesis of GMP from XMP.
   
  
 0.833
queF
NADPH dependent preQ0 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.
    
 0.677
truB
tRNA pseudouridine synthase B tRNA Psi55; Responsible for synthesis of pseudouridine from uracil-55 in the psi GC loop of transfer RNAs; Belongs to the pseudouridine synthase TruB family. Type 1 subfamily.
  
  
 0.583
NSP_38520
Hypothetical protein; Nsp38520; ORF_ID:nsp38520.
       0.567
psbK
Photosystem II protein PsbK; One of the components of the core complex of photosystem II (PSII). PSII is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation. It consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation.
       0.543
aspS
Aspartyl-tRNA synthetase Aspartyl-tRNA(Asn) synthetase unambiguous; 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.
 
    0.515
NSP_39850
Rod shape-determining protein MreC; Nsp39850; ORF_ID:nsp39850.
  
    0.514
NSP_44620
Ribosomal RNA small subunit methyltransferase B; Specifically methylates the cytosine at position 967 (m5C967) of 16S rRNA.
