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.

rphRibonuclease PH; Phosphorolytic 3'-5' exoribonuclease that plays an important role in tRNA 3'-end maturation. Removes nucleotide residues following the 3'-CCA terminus of tRNAs; can also add nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates, but this may not be physiologically important. Probably plays a role in initiation of 16S rRNA degradation (leading to ribosome degradation) during starvation. Plays a role in the secondary pathway of 23S rRNA 3' end maturation. (245 aa)    
Predicted Functional Partners:
rnr
Ribonuclease R; 3'-5' exoribonuclease that releases 5'-nucleoside monophosphates and is involved in maturation of structured RNAs.
   
 0.997
rdgB
Inosine/xanthosine triphosphate pyrophosphatase (subunit A); 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.
 
  
 0.994
yhaM
3'-5' exonuclease; Shows a 3'-5' exoribonuclease activity as well as single- stranded DNA 3'-5'exonuclease activity. Plays a role in the secondary pathway of 23S rRNA 3' end maturation; Belongs to the YhaM family.
   
  
 0.938
rhaB
Rhamnulokinase; Involved in the catabolism of L-rhamnose (6-deoxy-L-mannose). Catalyzes the transfer of the gamma-phosphate group from ATP to the 1- hydroxyl group of L-rhamnulose to yield L-rhamnulose 1-phosphate. Belongs to the rhamnulokinase family.
      
 0.905
rnz
Ribosomal protein L31C pseudogene; Zinc phosphodiesterase, which displays some tRNA 3'- processing endonuclease activity. Probably involved in tRNA maturation, by removing a 3'-trailer from precursor tRNA.
  
  
 0.893
araD
L-ribulose-5-phosphate 4-epimerase; Involved in the degradation of L-arabinose. Catalyzes the interconversion of L-ribulose 5-phosphate (LRu5P) and D-xylulose 5- phosphate (D-Xu5P) via a retroaldol/aldol mechanism (carbon-carbon bond cleavage analogous to a class II aldolase reaction).
   
  
 0.878
ysnB
Phosphoesterase; Evidence 2b: Function of strongly homologous gene; Product type e: enzyme; Belongs to the metallophosphoesterase superfamily. YfcE family.
  
  
 0.869
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 [...]

rpsD
Ribosomal protein S4 (BS4); One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the body of the 30S subunit. S4 represses its own expression; it is not know if this is at the level of translation or of mRNA stability; Belongs to the universal ribosomal protein uS4 family.
  
  0.846
araB
L-ribulokinase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme; Belongs to the ribulokinase family.
