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_0570Conserved hypothetical protein; Similar to PID:1256896 PID:1256896 PID:1360566 percent identity: 35.35; identified by sequence similarity; putative. (223 aa)    
Predicted Functional Partners:
fusA
Translation elongation factor EF-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 (By similarity); Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase [...]

hemC
Porphobilinogen deaminase (hemC); Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps.
       0.927
MJ_1116
Asparagine synthetase (asnB); Similar to GB:J05554 SP:P22106 PID:145393 GB:U00096 PID:1651277 percent identity: 33.78; identified by sequence similarity; putative; Belongs to the asparagine synthetase family.
      0.911
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.
 
 
 0.894
dph2
Conserved hypothetical protein; 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.
  
   
 0.708
hisC
Histidinol-phosphate aminotransferase (hisC); Similar to SP:P06986 GB:U02071 GB:X03416 PID:41695 PID:41710 percent identity: 29.00; identified by sequence similarity; putative.
     
 0.491
srp54
Signal recognition particle, subunit SRP54; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY. Belongs to the GTP-binding SRP family. SRP54 subfamily.
  
    0.464
MJ_0085
Iron transport periplasmic binding protein, putative (ceuE); Similar to PID:1107531 percent identity: 25.10; identified by sequence similarity; putative.
       0.431
cobD
Cobalamin biosynthesis protein B (cbiB); Converts cobyric acid to cobinamide by the addition of aminopropanol on the F carboxylic group.
       0.431
queC
ExsB; Catalyzes the ATP-dependent conversion of 7-carboxy-7- deazaguanine (CDG) to 7-cyano-7-deazaguanine (preQ(0)). Belongs to the QueC family.
