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

rnrRibonuclease R; 3'-5' exoribonuclease that releases 5'-nucleoside monophosphates and is involved in maturation of structured RNAs. (769 aa)    
Predicted Functional Partners:
AMW32730.1
ADP-ribose pyrophosphatase; Derived by automated computational analysis using gene prediction method: Protein Homology.
   
 0.935
smpB
SsrA-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 [...]

AMW32414.1
2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the IspD/TarI cytidylyltransferase family. IspD subfamily.
  
   0.802
AMW33051.1
tRNA nucleotidyltransferase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the tRNA nucleotidyltransferase/poly(A) polymerase family.
  
 0.796
ligA
DNA ligase (NAD(+)) LigA; DNA ligase that catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double- stranded DNA using NAD as a coenzyme and as the energy source for the reaction. It is essential for DNA replication and repair of damaged DNA; Belongs to the NAD-dependent DNA ligase family. LigA subfamily.
       0.773
AMW32924.1
RNA methyltransferase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the class IV-like SAM-binding methyltransferase superfamily. RNA methyltransferase TrmH family.

AMW32225.1
Ribonuclease; Derived by automated computational analysis using gene prediction method: Protein Homology.
    
 0.740
pnp
Polyribonucleotide nucleotidyltransferase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction.
   
 
 0.739
NA23_05280
Phosphate starvation-inducible protein PhoH; Derived by automated computational analysis using gene prediction method: Protein Homology.
   
 0.711
AMW33607.1
Non-canonical purine NTP pyrophosphatase; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family.
