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

queG4Fe-4S ferredoxin, iron-sulfur cluster binding protein; 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); Belongs to the QueG family. (348 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).

Gst
IMG reference gene:2512956187; PFAM: Glutathione S-transferase, N-terminal domain; Glutathione S-transferase, C-terminal domain; truncated by 20 aa.

RSP_1032
Putative O6-methylguanine-DNA methyltransferase; IMG reference gene:2512956072; PFAM: 6-O-methylguanine DNA methyltransferase, DNA binding domain; TIGRFAM: O-6-methylguanine DNA methyltransferase.

RSP_1142
Putative membrane protein; IMG reference gene:2512956185; PFAM: Protein of unknown function (DUF1294).

mtgA
Peptidoglycan transglycosylase; Peptidoglycan polymerase that catalyzes glycan chain elongation from lipid-linked precursors; Belongs to the glycosyltransferase 51 family.
  
    0.628
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 [...]

gltB
Glutamine-pyruvate aminotransferase; IMG reference gene:2512956189; PFAM: Conserved region in glutamate synthase; GXGXG motif; Glutamate synthase central domain; Glutamine amidotransferases class-II.
       0.532
RSP_1141
Hypothetical protein; IMG reference gene:2512956184.
       0.517
azoR
Putative acyl carrier protein phosphodiesterase; Catalyzes the reductive cleavage of azo bond in aromatic azo compounds to the corresponding amines. Requires NADH, but not NADPH, as an electron donor for its activity; Belongs to the azoreductase type 1 family.
 
      0.517
exsB
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.
