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.

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.
 
  
 0.993
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.
   
 0.868
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).
   
 
 0.859
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.
   
  0.857
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.
   
  0.811
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.
   
   0.750
rpsA
30S ribosomal subunit protein S1; Binds mRNA; thus facilitating recognition of the initiation point. It is needed to translate mRNA with a short Shine-Dalgarno (SD) purine-rich sequence.
   
 
 0.746
pnp
Polynucleotide phosphorylase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction. Is a global regulator of virulence and persistency.
   
  
 0.718
yobF
Putative cytoplasmic protein; Similar to E. coli orf, hypothetical protein (AAC74894.1); Blastp hit to AAC74894.1 (47 aa), 93% identity in aa 1 - 47.
      
 0.715
