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.

trm5bConserved hypothetical protein; Specifically methylates the N1 position of guanosine-37 in various tRNAs. (336 aa)    
Predicted Functional Partners:
MJ_0882
Conserved hypothetical protein; Probable methyltransferase that uses S-adenosylmethionine as the methyl donor. Binds neither NAD nor NADP in vitro.
  
    0.908
taw1
Conserved hypothetical protein; Component of the wyosine derivatives biosynthesis pathway that catalyzes the condensation of N-methylguanine with 2 carbon atoms from pyruvate to form the tricyclic 4-demethylwyosine (imG-14) on guanosine-37 of tRNA(Phe).
 
 
 0.863
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.
 
  
 0.828
rfcL
Activator 1 (replication factor C), 53 KD subunit; Part of the RFC clamp loader complex which loads the PCNA sliding clamp onto DNA; Belongs to the activator 1 small subunits family. RfcL subfamily.
 
     0.816
tfb
Transcription initiation factor IIB (TFIIB); Stabilizes TBP binding to an archaeal box-A promoter. Also responsible for recruiting RNA polymerase II to the pre-initiation complex (DNA-TBP-TFIIB).
 
     0.721
taw3
Conserved hypothetical protein; S-adenosyl-L-methionine-dependent methyltransferase that acts as a component of the wyosine derivatives biosynthesis pathway. Probably methylates N-4 position of wybutosine-86 to produce wybutosine-72; Belongs to the TYW3 family.
 
  
 0.687
hel308
Putative SKI2-family helicase; DNA-dependent ATPase and 3'-5' DNA helicase that may be involved in repair of stalled replication forks; Belongs to the helicase family. Hel308 subfamily.
 
     0.681
MJ_1136
Conserved 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 [...]

MJ_0719
RNase L inhibitor; Similar to PIR:S63672 percent identity: 48.74; identified by sequence similarity; putative; Belongs to the ABC transporter superfamily.
 
    0.671
MJ_0443
Conserved hypothetical protein; Similar to GB:X59720 SP:P25586 PID:5300 percent identity: 27.78; identified by sequence similarity; putative.
