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

mnmHtRNA 2-selenouridine synthase; Involved in the post-transcriptional modification of the uridine at the wobble position (U34) of tRNA(Lys), tRNA(Glu) and tRNA(Gln). Catalyzes the conversion of 2-thiouridine (S2U-RNA) to 2-selenouridine (Se2U-RNA). Acts in a two-step process involving geranylation of 2-thiouridine (S2U) to S-geranyl-2-thiouridine (geS2U) and subsequent selenation of the latter derivative to 2-selenouridine (Se2U) in the tRNA chain. (364 aa)    
Predicted Functional Partners:
selD
Selenophosphate synthase; Synthesizes selenophosphate from selenide and ATP; Belongs to the selenophosphate synthase 1 family. Class I subfamily.
   
 0.995
ydiU
UPF0061 family protein; Catalyzes the transfer of adenosine 5'-monophosphate (AMP) to Ser, Thr and Tyr residues of target proteins (AMPylation). Cannot use GTP, CTP or UTP as cosubstrate. AMPylates SucA at 'Thr-405' and GrxA on 'Tyr-13'. Regulates protein S-glutathionylation levels probably by AMPylation of deglutathionylation enzymes such as GrxA. Probably involved in redox homeostasis.
      
 0.917
selB
selenocysteinyl-tRNA-specific translation factor; Translation factor necessary for the incorporation of selenocysteine into proteins. It probably replaces EF-Tu for the insertion of selenocysteine directed by the UGA codon. SelB binds GTP and GDP; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. SelB subfamily.
  
   
 0.912
selA
Selenocysteine synthase; Converts seryl-tRNA(Sec) to selenocysteinyl-tRNA(Sec) required for selenoprotein biosynthesis. Requires selenophosphate as the selenium-donor molecule; Belongs to the SelA family.
 
   
 0.873
mnmC
tRNA 5-methylaminomethyl-2-thiouridine biosynthesis bifunctional protein MnmC; Catalyzes the last two steps in the biosynthesis of 5- methylaminomethyl-2-thiouridine (mnm(5)s(2)U) at the wobble position (U34) in tRNA. Catalyzes the FAD-dependent demodification of cmnm(5)s(2)U34 to nm(5)s(2)U34, followed by the transfer of a methyl group from S-adenosyl-L-methionine to nm(5)s(2)U34, to form mnm(5)s(2)U34; In the N-terminal section; belongs to the methyltransferase superfamily. tRNA (mnm(5)s(2)U34)-methyltransferase family.
  
  
 0.832
yqeB
XdhC-CoxI family protein with NAD(P)-binding Rossman fold; Putative synthases.
      
 0.809
yqeC
Putative selenium-dependent hydroxylase accessory protein.
      
 0.783
mnmA
tRNA(Gln,Lys,Glu) U34 2-thiouridylase; Catalyzes the 2-thiolation of uridine at the wobble position (U34) of tRNA(Lys), tRNA(Glu) and tRNA(Gln), leading to the formation of s(2)U34, the first step of tRNA-mnm(5)s(2)U34 synthesis. Sulfur is provided by IscS, via a sulfur-relay system. Binds ATP and its substrate tRNAs.
      
 0.704
thiI
tRNA s(4)U8 sulfurtransferase; Catalyzes the ATP-dependent transfer of a sulfur to tRNA to produce 4-thiouridine in position 8 of tRNAs, which functions as a near-UV photosensor. Also catalyzes the transfer of sulfur to the sulfur carrier protein ThiS, forming ThiS-thiocarboxylate. This is a step in the synthesis of thiazole, in the thiamine biosynthesis pathway. The sulfur is donated as persulfide by IscS. Belongs to the ThiI family.
  
  
 0.675
allS
allD operon transcriptional activator; Positive regulator essential for the expression of allD operon. Binds to the allD promoter; Belongs to the LysR transcriptional regulatory family.
