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

rtcBConserved hypothetical protein; GTP-dependent RNA ligase that is involved in tRNA splicing and RNA repair. Joins RNA with 2',3'-cyclic-phosphate or 3'-phosphate ends to RNA with 5'-hydroxy ends; Belongs to the RtcB family. (968 aa)    
Predicted Functional Partners:
MJ_0024
Conserved hypothetical protein; Activates the tRNA-splicing ligase complex by facilitating the enzymatic turnover of catalytic subunit RtcB. Acts by promoting the guanylylation of RtcB, a key intermediate step in tRNA ligation. Can also alter the NTP specificity of RtcB such that ATP, dGTP or ITP is used efficiently (By similarity).
 
 0.994
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).

eIF1A
Translation initiation factor aIF-1A; Seems to be required for maximal rate of protein biosynthesis. Enhances ribosome dissociation into subunits and stabilizes the binding of the initiator Met-tRNA(I) to 40 S ribosomal subunits (By similarity).
     
 0.969
eif2a
Translation initiation factor aIF-2, subunit alpha (aif2A); eIF-2 functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA; Belongs to the eIF-2-alpha family.
   
  
 0.938
MJ_0251
Ferredoxin II; Similar to SP:P00211 percent identity: 37.04; identified by sequence similarity; putative.
      
 0.825
dys
Deoxyhypusine synthase (dys1); Catalyzes the NAD-dependent oxidative cleavage of spermidine and the subsequent transfer of the butylamine moiety of spermidine to the epsilon-amino group of a specific lysine residue of the eIF-5A precursor protein to form the intermediate deoxyhypusine residue.
 
   
 0.745
MJ_1568
Conserved hypothetical protein; Hydrolyzes RNA 2',3'-cyclic phosphodiester to an RNA 2'- phosphomonoester; Belongs to the 2H phosphoesterase superfamily. ThpR family.
 
   
 0.743
MJ_0590
Conserved hypothetical protein; Catalyzes the formation of acetate and ATP from acetyl-CoA by using ADP and phosphate. Can also use butyryl-CoA, but not phenylacetyl-CoA. Cannot catalyze the reverse reaction. In the N-terminal section; belongs to the acetate CoA ligase alpha subunit family.
   
   0.741
MJ_0683
Conserved hypothetical protein; Similar to GB:AE000782 percent identity: 38.10; identified by sequence similarity; putative.
       0.706
prf1
Peptide chain release factor aRF, subunit 1; Directs the termination of nascent peptide synthesis (translation) in response to the termination codons UAA, UAG and UGA.
