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; Belongs to the Protein of unknown function UPF0027 family (IPR001233). (479 aa)    
Predicted Functional Partners:
MCP_2029
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.
 
 0.987
rtcA
RNA 3'-terminal phosphate cyclase; 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.

MCP_2030
Conserved hypothetical protein.
       0.737
prf1
Peptide chain release factor subunit 1; Directs the termination of nascent peptide synthesis (translation) in response to the termination codons UAA, UAG and UGA.
  
    0.690
flpA
rRNA/tRNA 2'-O-methyltransferase; Involved in pre-rRNA and tRNA processing. Utilizes the methyl donor S-adenosyl-L-methionine to catalyze the site-specific 2'-hydroxyl methylation of ribose moieties in rRNA and tRNA. Site specificity is provided by a guide RNA that base pairs with the substrate. Methylation occurs at a characteristic distance from the sequence involved in base pairing with the guide RNA; Belongs to the methyltransferase superfamily. Fibrillarin family.
   
 0.645
MCP_2059
Putative ATP-dependent RNA helicase; Belongs to the DEAD box helicase family.
   
 0.645
MCP_2027
Hypothetical protein; Contains two Tetratricopeptide TPR_2 repeat (IPR013105).
     
 0.631
MCP_2698
Protein kinase; Contains at least one Tetratricopeptide region domain (IPR013026); Contains at least three Tetratricopeptide TPR_1 repeats (IPR001440).; Contains at least five Tetratricopeptide TPR_2repeats (IPR013105).
   
 
 0.515
MCP_2031
Conserved hypothetical protein; Contains at least PBS lyase HEAT-like repeat (IPR004155).
       0.507
eif2a
Translation initiation factor 2 alpha subunit.
   
  
 0.505
