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

rncRibonuclease III; Digests double-stranded RNA. Involved in the processing of ribosomal RNA transcript to yield the immediate precursors to the large and small rRNAs (23S and 16S). Also processes pre-scRNA (the precursor of the signal recognition particle RNA). Probably also processes some mRNAs, and tRNAs when they are encoded in the rRNA operon. Probably processes pre-crRNA and tracrRNA of type II CRISPR loci if present in the organism. (249 aa)    
Predicted Functional Partners:
rpsO
Ribosomal protein S15 (BS18); One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it helps nucleate assembly of the platform of the 30S subunit by binding and bridging several RNA helices of the 16S rRNA.
 
 
 0.974
ftsY
Signal recognition particle (docking protein); Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Acts as a receptor for the complex formed by the signal recognition particle (SRP) and the ribosome-nascent chain (RNC).
  
  
 0.946
pnpA
Polynucleotide phosphorylase (PNPase); Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction. Necessary for competence development in Bacillus subtilis. May be necessary for modification of the srfA transcript (stabilization or translation activation).
  
  
 0.944
rny
Endoribonuclease Y; Endoribonuclease that initiates mRNA decay. Initiates the decay of all SAM-dependent riboswitches, such as yitJ riboswitch. Involved in processing of the gapA operon mRNA, it cleaves between cggR and gapA. Is also the decay-initiating endonuclease for rpsO mRNA. Belongs to the RNase Y family.
   
  
 0.942
rnr
Ribonuclease R; 3'-5' exoribonuclease that releases 5'-nucleoside monophosphates and is involved in maturation of structured RNAs.
   
 
 0.940
rnjA
Ribonuclease J1; An RNase that has endonuclease and 5'-3' exonuclease activity, playing a role in both rRNA and mRNA stability and degradation. Endonuclease activity can cleave within 4 nucleotides of the 5'-end of a triphosphorylated RNA. Endonuclease digestion by the RNase J1/J2 complex occurs at a different site and in some cases more efficiently than J1 or J2 alone. The exonuclease activity of the J1/J2 complex is highly processive on substrates longer than 5 nucleotides, on shorter substrates is distributive. Preferentially cleaves ssRNA, possibly in AU-rich regions. The 5'-exonuc [...]

era
GTP-binding protein; An essential GTPase that binds both GDP and GTP, with rapid nucleotide exchange. Plays a role in 16S rRNA processing and 30S ribosomal subunit biogenesis and possibly also in cell cycle regulation and energy metabolism (By similarity). Binds both GDP and GTP. Complements an E.coli era disruption mutant; Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. Era GTPase family.

rplQ
Ribosomal protein L17 (BL15); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type s: structure.
   
 
 0.926
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; Belongs to the bacterial ribosomal protein bL19 family.

rpsI
Ribosomal protein S9; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type s: structure.
