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

MJ_1136Conserved hypothetical protein; tRNA uridine(34) acetyltransferase, which mediates formation of carboxymethyluridine in the wobble base at position 34 in tRNAs. The proposed mechanism is the following: (i) recruits S-adenosyl-L- methionine and cleaves it to generate a 5'-deoxyadenosine radical (5'- dA) in the radical S-adenosyl-L-methionine (rSAM) region, (ii) hydrolyzes acetyl-CoA in the N-acetyltransferase domain and (iii) an acetyl radical is formed by the products of the two domains and (iv) is transferred onto the C5 position of uridine(34) in the bound tRNA molecule. Does not sho [...] (541 aa)    
Predicted Functional Partners:
pstK
Yeast KTI12 Protein; Specifically phosphorylates seryl-tRNA(Sec) to O- phosphoseryl-tRNA(Sec), an activated intermediate for selenocysteine biosynthesis.
  
 
 0.921
tuf
Translation elongation factor EF-1, subunit alpha; This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis. Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. EF-Tu/EF-1A subfamily.
    
 
 0.754
rtcA
Hypothetical protein; Catalyzes the conversion of 3'-phosphate to a 2',3'-cyclic phosphodiester at the end of RNA. The mechanism of action of the enzyme occurs in 3 steps: (A) adenylation of the enzyme by ATP; (B) transfer of adenylate to an RNA-N3'P to produce RNA-N3'PP5'A; (C) and attack of the adjacent 2'-hydroxyl on the 3'-phosphorus in the diester linkage to produce the cyclic end product. The biological role of this enzyme is unknown but it is likely to function in some aspects of cellular RNA processing (By similarity).

MJ_1650
Conserved hypothetical protein; Similar to GB:AE000666 percent identity: 31.03; identified by sequence similarity; putative.
   
  
 0.733
rsmA
Dimethyladenosine transferase (ksgA); Specifically dimethylates two adjacent adenosines in the loop of a conserved hairpin near the 3'-end of 16S rRNA in the 30S particle. May play a critical role in biogenesis of 30S subunits. Belongs to the class I-like SAM-binding methyltransferase superfamily. rRNA adenine N(6)-methyltransferase family. RsmA subfamily.
  
  
 0.628
truA
Pseudouridylate synthase I (truA); Formation of pseudouridine at positions 38, 39 and 40 in the anticodon stem and loop of transfer RNAs; Belongs to the tRNA pseudouridine synthase TruA family.
   
 
 0.628
dphB
Diphthine synthase (dph5); S-adenosyl-L-methionine-dependent methyltransferase that catalyzes the trimethylation of the amino group of the modified target histidine residue in translation elongation factor 2 (EF-2), to form an intermediate called diphthine. The three successive methylation reactions represent the second step of diphthamide biosynthesis.
  
  
 0.597
trm1
N2,N2-dimethylguanosine tRNA methyltransferase (trm1); Dimethylates a single guanine residue at position 26 of a number of tRNAs using S-adenosyl-L-methionine as donor of the methyl groups; Belongs to the class I-like SAM-binding methyltransferase superfamily. Trm1 family.

rpoD
DNA-directed RNA polymerase, subunit D (rpoD); DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
