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

rtcARNA 3'-terminal phosphate cyclase (with b3419); 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. (339 aa)    
Predicted Functional Partners:
rtcB
Putative cytoplasmic protein; Similar to E. coli orf, hypothetical protein (AAC76446.1); Blastp hit to AAC76446.1 (408 aa), 87% identity in aa 1 - 408.
 
  
 0.999
rtcR
Sigma N (sigma 54)-dependent regulator of rtcBA expression; EBP family; similar to E. coli putative 2-component regulator (AAC76447.1); Blastp hit to AAC76447.1 (532 aa), 84% identity in aa 1 - 527.
 
  
 0.992
rpsD
30S ribosomal subunit protein S4; One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the body of the 30S subunit.
   
 0.949
rnd
RNase D; Exonuclease involved in the 3' processing of various precursor tRNAs. Initiates hydrolysis at the 3'-terminus of an RNA molecule and releases 5'-mononucleotides; Belongs to the RNase D family.
   
  0.941
rpsK
30S ribosomal subunit protein S11; Located on the platform of the 30S subunit, it bridges several disparate RNA helices of the 16S rRNA. Forms part of the Shine- Dalgarno cleft in the 70S ribosome; Belongs to the universal ribosomal protein uS11 family.
    
  0.935
ypfI
Putative acetyltransferase; Catalyzes the formation of N(4)-acetylcytidine (ac(4)C) at the wobble position of tRNA(Met), by using acetyl-CoA as an acetyl donor and ATP (or GTP).
   
 
 0.917
rph
RNase PH; Phosphorolytic exoribonuclease that removes nucleotide residues following the -CCA terminus of tRNA and adds nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates.
   
 0.887
rpsL
30S ribosomal subunit protein S12; With S4 and S5 plays an important role in translational accuracy.
    
  0.830
ksgA
S-adenosylmethionine-6-N',N'-adenosyl (rRNA) dimethyltransferase; Specifically dimethylates two adjacent adenosines (A1518 and A1519) in the loop of a conserved hairpin near the 3'-end of 16S rRNA in the 30S particle. May play a critical role in biogenesis of 30S subunits.
   
   0.822
rpsQ
30S ribosomal subunit protein S17; One of the primary rRNA binding proteins, it binds specifically to the 5'-end of 16S ribosomal RNA.
    
  0.818
