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

Score
ornOligoribonuclease Orn; 3'-to-5' exoribonuclease specific for small oligoribonucleotides; Belongs to the oligoribonuclease family. (215 aa)    
Predicted Functional Partners:
nrnA
Conserved protein; Bifunctional enzyme which has both oligoribonuclease and pAp- phosphatase activities. Degrades RNA oligonucleotides with a length of 5 nucleotides and shorter, with a preference for 2-mers. Also degrades 24-mers. Converts 3'(2')-phosphoadenosine 5'-phosphate (PAP) to AMP.

cysQ
Monophosphatase CysQ; Phosphatase with a broad specificity. Its primary physiological function is to dephosphorylate 3'-phosphoadenosine 5'- phosphate (PAP) and 3'-phosphoadenosine 5'-phosphosulfate (PAPS). Thus, plays a role in mycobacterial sulfur metabolism, since it can serve as a key regulator of the sulfate assimilation pathway by controlling the pools of PAP and PAPS in the cell. To a lesser extent, is also able to hydrolyze inositol 1-phosphate (I-1-P), fructose 1,6-bisphosphate (FBP) (to fructose 6-phosphate (F-6-P)) and AMP in vitro, but this might not be significant in vivo.

pcnA
Poly(A) polymerase PcnA; Rv3907c, (MTCY15F10.04), len: 480 aa. Probable pcnA,polynucleotide polymerase, equivalent to Q9CCY1|PCNA|ML2697 PCNA protein from Mycobacterium leprae (486 aa), FASTA scores: opt: 2713, E(): 4.3e-160, (84.1% identity in 478 aa overlap); and Q59534|PCNB POLYA polymerase from Mycobacterium leprae (411 aa) FASTA scores: opt: 2077, E(): 7.1e-121, (82.55% identity in 373 aa overlap). Also highly similar to many e.g. Q9X8T2|SCH24.18 putative RNA nucleotidyltransferase from Streptomyces coelicolor (483 aa), FASTA scores: opt: 1856, E(): 3.7e-107, (61.55% identity in 4 [...]

rphA
Probable ribonuclease RphA (RNase PH) (tRNA nucleotidyltransferase); 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.
  
  
 0.735
gpsI
Polyribonucleotide nucleotidyltransferase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction.
  
   
 0.637
Rv2510c
Conserved protein; Rv2510c, (MTCY07A7.16c), len: 533 aa. Conserved protein, highly similar, but longer approximately 20 aa, to others e.g. Q9ABY0|CC0090 hypothetical protein from Caulobacter crescentus (516 aa), FASTA scores: opt: 1282,E(): 8.4e-63, (45.1% identity in 490 aa overlap); Q9A130|SPY0500 hypothetical protein from Streptococcus pyogenes (500 aa), FASTA scores: opt: 1281, E(): 9.3e-63,(43.8% identity in 491 aa overlap); Q985L5|MLR7622 hypothetical protein from Rhizobium loti (Mesorhizobium loti) (515 aa), FASTA scores: opt: 1259, E(): 1.5e-61,(44.1% identity in 510 aa overlap [...]
  
    0.633
rnj
Conserved hypothetical protein; An RNase that has 5'-3' exonuclease and possible endonuclease activity. Involved in maturation of rRNA and in some organisms also mRNA maturation and/or decay (By similarity). Has both beta-lactamase and RNase activity, but the physiological relevance of the beta- lactamase activity, i.e. whether it confers antibiotic resistance, has not been shown ; Belongs to the metallo-beta-lactamase superfamily. RNA- metabolizing metallo-beta-lactamase-like family. Bacterial RNase J subfamily.

rne
Rv2444c, (MTCY428.02), len: 953 aa. Possible rne,ribonuclease E, highly similar to others e.g. Q9CBZ1|ML1468 possible ribonuclease from Mycobacterium leprae (924 aa),FASTA scores: opt: 3713, E(): 2.4e-174, (74.2% identity in 966 aa overlap); Q9SI08|AT2G04270 putative ribonuclease E from Arabidopsis thaliana (502 aa), FASTA scores: opt: 674,E(): 7.5e-26, (31.2% identity in 410 aa overlap); etc. Similar at C-terminal end to P21513|RNE_ECOLI|ams|HMP1|B1084 ribonuclease E (RNASE E) from Escherichia coli strain K12 (1061 aa), FASTA scores: opt: 554, E(): 9.9e-20, (37.8% identity in 386 aa o [...]

alaS
Probable alanyl-tRNA synthetase AlaS (alanine--tRNA ligase) (alanine translase) (ALARS); Catalyzes the attachment of alanine to tRNA(Ala) in a two- step reaction: alanine is first activated by ATP to form Ala-AMP and then transferred to the acceptor end of tRNA(Ala). Also edits incorrectly charged Ser-tRNA(Ala) and Gly-tRNA(Ala) via its editing domain; Belongs to the class-II aminoacyl-tRNA synthetase family.
      
 0.544
infC
Probable initiation factor if-3 InfC; IF-3 binds to the 30S ribosomal subunit and shifts the equilibrum between 70S ribosomes and their 50S and 30S subunits in favor of the free subunits, thus enhancing the availability of 30S subunits on which protein synthesis initiation begins.
