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

dphBDiphthine synthase; 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. (257 aa)    
Predicted Functional Partners:
fusA
Translation elongation factor aEF-2; Catalyzes the GTP-dependent ribosomal translocation step during translation elongation. During this step, the ribosome changes from the pre-translocational (PRE) to the post-translocational (POST) state as the newly formed A-site-bound peptidyl-tRNA and P-site-bound deacylated tRNA move to the P and E sites, respectively. Catalyzes the coordinated movement of the two tRNA molecules, the mRNA and conformational changes in the ribosome; Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. EF-G/EF [...]

AGB15826.1
Diphthine-ammonia ligase; PFAM: ATP-binding region; TIGRFAM: MJ0570-related uncharacterized domain; TIGR00289 family protein; arCOG00187 universal archaeal metal-binding-domain/4Fe-4S-binding-domain containing ABC transporter, ATP-binding protein.
 
 
 0.831
AGB15965.1
Diphthamide biosynthesis enzyme Dph2; Catalyzes the first step of diphthamide biosynthesis, i.e. the transfer of the 3-amino-3-carboxypropyl group from S-adenosyl-L- methionine (SAM) to the C2 position of the imidazole ring of the target histidine residue in translation elongation factor 2 (EF-2). Belongs to the DPH1/DPH2 family.

AGB16729.1
PFAM: GTPase of unknown function; TGS domain; TIGRFAM: small GTP-binding protein domain.
  
    0.692
pelA
Putative translation factor pelota; May function in recognizing stalled ribosomes, interact with stem-loop structures in stalled mRNA molecules, and effect endonucleolytic cleavage of the mRNA. May play a role in the release non-functional ribosomes and degradation of damaged mRNAs. Has endoribonuclease activity.
  
    0.675
AGB16746.1
20S proteasome subunit (alpha or beta); Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. Belongs to the peptidase T1A family.
  
     0.656
rpl19e
Ribosomal protein L19E; Binds to the 23S rRNA; Belongs to the eukaryotic ribosomal protein eL19 family.
  
    0.655
psmA
Proteasome endopeptidase complex, archaeal, alpha subunit; Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation.
  
     0.651
rps4e
PFAM: Ribosomal family S4e; RS4NT (NUC023) domain; Belongs to the eukaryotic ribosomal protein eS4 family.
  
    0.651
prf1
Peptide chain release factor eRF/aRF, subunit 1; Directs the termination of nascent peptide synthesis (translation) in response to the termination codons UAA, UAG and UGA.
