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.

smpBSsrA-binding protein; Required for rescue of stalled ribosomes mediated by trans- translation. Binds to transfer-messenger RNA (tmRNA), required for stable association of tmRNA with ribosomes. tmRNA and SmpB together mimic tRNA shape, replacing the anticodon stem-loop with SmpB. tmRNA is encoded by the ssrA gene; the 2 termini fold to resemble tRNA(Ala) and it encodes a 'tag peptide', a short internal open reading frame. During trans-translation Ala-aminoacylated tmRNA acts like a tRNA, entering the A-site of stalled ribosomes, displacing the stalled mRNA. The ribosome then switches to [...] (151 aa)    
Predicted Functional Partners:
rplS
Ribosomal protein L19; This protein is located at the 30S-50S ribosomal subunit interface and may play a role in the structure and function of the aminoacyl-tRNA binding site.
 
 
 0.983
rplT
Ribosomal protein L20; Binds directly to 23S ribosomal RNA and is necessary for the in vitro assembly process of the 50S ribosomal subunit. It is not involved in the protein synthesizing functions of that subunit.
 
 
 
 0.919
rsmI
Phosphocarrier, HPr family; Catalyzes the 2'-O-methylation of the ribose of cytidine 1402 (C1402) in 16S rRNA.
 
   
 0.918
rpsP
COGs: COG0228 Ribosomal protein S16; InterPro IPR000307:IPR020592; KEGG: sat:SYN_00765 SSU ribosomal protein S16P; PFAM: ribosomal protein S16; SPTR: C8QYR0 Ribosomal protein S16; TIGRFAM: ribosomal protein S16; PFAM: Ribosomal protein S16; TIGRFAM: ribosomal protein S16; Belongs to the bacterial ribosomal protein bS16 family.
  
 
 0.917
rpsB
COGs: COG0052 Ribosomal protein S2; InterPro IPR005706:IPR001865:IPR018130; KEGG: gur:Gura_3733 30S ribosomal protein S2; PFAM: ribosomal protein S2; SPTR: A5G7W8 30S ribosomal protein S2; TIGRFAM: ribosomal protein S2; PFAM: Ribosomal protein S2; TIGRFAM: ribosomal protein S2, bacterial type; Belongs to the universal ribosomal protein uS2 family.
 
 
 0.911
rpsO
Ribosomal protein S15; Forms an intersubunit bridge (bridge B4) with the 23S rRNA of the 50S subunit in the ribosome.
 
 
 0.911
rpsE
Ribosomal protein S5; Located at the back of the 30S subunit body where it stabilizes the conformation of the head with respect to the body. Belongs to the universal ribosomal protein uS5 family.
  
 
 0.911
rpsR
Ribosomal protein S18; Binds as a heterodimer with protein S6 to the central domain of the 16S rRNA, where it helps stabilize the platform of the 30S subunit; Belongs to the bacterial ribosomal protein bS18 family.
  
 
 
 0.910
rplC
50S ribosomal protein L3; One of the primary rRNA binding proteins, it binds directly near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit; Belongs to the universal ribosomal protein uL3 family.
  
 
 0.906
rpsM
30S ribosomal protein S13; Located at the top of the head of the 30S subunit, it contacts several helices of the 16S rRNA. In the 70S ribosome it contacts the 23S rRNA (bridge B1a) and protein L5 of the 50S subunit (bridge B1b), connecting the 2 subunits; these bridges are implicated in subunit movement. Contacts the tRNAs in the A and P-sites. Belongs to the universal ribosomal protein uS13 family.
