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

queFPutative GTP cyclohydrolase I; Catalyzes the NADPH-dependent reduction of 7-cyano-7- deazaguanine (preQ0) to 7-aminomethyl-7-deazaguanine (preQ1). (282 aa)    
Predicted Functional Partners:
queC
Conserved hypothetical protein; Catalyzes the ATP-dependent conversion of 7-carboxy-7- deazaguanine (CDG) to 7-cyano-7-deazaguanine (preQ(0)); Belongs to the QueC family.

ECA3553
Similar to Escherichia coli, Escherichia coli O157:H7, and Shigella flexneri putative 6-pyruvoyl tetrahydrobiopterin synthase YgcM or b2765 or z4075 or ecs3620 or sf2781 SWALL:PTPS_ECOLI (SWALL:Q46903) (121 aa) fasta scores: E(): 8.1e-44, 86.66% id in 120 aa.

nrdG
Anaerobic ribonucleoside-triphosphate reductase activating protein; Activation of anaerobic ribonucleoside-triphosphate reductase under anaerobic conditions by generation of an organic free radical, using S-adenosylmethionine and reduced flavodoxin as cosubstrates to produce 5'-deoxy-adenosine.
  
  
 0.798
queE
Conserved hypothetical 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.
  
  
 0.798
ECA4354
Putative 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.
  
  
 0.762
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 th [...]

ECA1153
Putative exported protein; Similar to Salmonella typhimurium, and Salmonella typhi putative DNA uptake protein and related dna-binding proteins ybav or stm0453 or sty0495 SWALL:Q8XGV0 (EMBL:AE008716) (124 aa) fasta scores: E(): 5.3e-15, 48.78% id in 123 aa, and to Escherichia coli, and Shigella flexneri hypothetical protein ybav precursor ybav or b0442 or sf0387 SWALL:AAN42043 (EMBL:AE000150) (123 aa) fasta scores: E(): 2.8e-13, 49.19% id in 124 aa.

syd
Putative SecY-interacting protein; Interacts with the SecY protein in vivo. May bind preferentially to an uncomplexed state of SecY, thus functioning either as a chelating agent for excess SecY in the cell or as a regulatory factor that negatively controls the translocase function. Belongs to the Syd family.

secY
Preprotein translocase subunit; The central subunit of the protein translocation channel SecYEG. Consists of two halves formed by TMs 1-5 and 6-10. These two domains form a lateral gate at the front which open onto the bilayer between TMs 2 and 7, and are clamped together by SecE at the back. The channel is closed by both a pore ring composed of hydrophobic SecY resides and a short helix (helix 2A) on the extracellular side of the membrane which forms a plug. The plug probably moves laterally to allow the channel to open. The ring and the pore may move independently.
