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

gpsIPolyribonucleotide nucleotidyltransferase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction. (752 aa)    
Predicted Functional Partners:
rhlE
Rv3211, (MTCY07D11.15c), len: 527 aa. Probable rhlE,ATP-dependent RNA helicase, equivalent (but shorter 22 aa) to Q9CCH3|RHLE|ML0811 putative ATP-dependent RNA helicase from Mycobacterium leprae (544 aa), FASTA scores: opt: 2497, E(): 8.7e-131, (74.75% identity in 531 aa overlap). Also highly similar to other RNA helicases e.g. Q9FBJ2|SCP8.29c from Streptomyces coelicolor (879 aa),FASTA scores: opt: 1458, E(): 3.6e-73, (52.5% identity in 522 aa overlap); Q9DF36 from Xenopus laevis (African clawed frog) (800 aa), FASTA scores: opt: 792, E(): 2.3e-36,(37.15% identity in 385 aa overlap); [...]

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 [...]

rho
Probable transcription termination factor Rho homolog; Facilitates transcription termination by a mechanism that involves Rho binding to the nascent RNA, activation of Rho's RNA- dependent ATPase activity, and release of the mRNA from the DNA template. Shows poor RNA-dependent ATP hydrolysis and inefficient DNA- RNA unwinding activities, but exhibits robust and fast transcription termination, which suggests that the transcription termination function of M.tuberculosis Rho is not correlated with its helicase/translocase activities and that these functions may not be important for its RN [...]

rplC
50S ribosomal protein L3 RplC; 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.
  
  
 0.954
rplD
50S ribosomal protein L4 RplD; One of the primary rRNA binding proteins, this protein initially binds near the 5'-end of the 23S rRNA. It is important during the early stages of 50S assembly. It makes multiple contacts with different domains of the 23S rRNA in the assembled 50S subunit and ribosome.

pepR
Rv2782c, (MTV002.47c), len: 438 aa.

rpsA
30S ribosomal protein S1 RpsA; Binds mRNA, facilitating recognition of most mRNAs by the 30S ribosomal subunit during translation initiation (By similarity). Probably plays a role in trans-translation; binds tmRNA (the product of the ssrA gene). In trans-translation Ala- aminoacylated transfer-messenger RNA (tmRNA, product of the ssrA gene; the 2 termini fold to resemble tRNA(Ala) while it encodes a short internal open reading frame (the tag peptide)) acts like a tRNA, entering the A-site of the ribosome and displacing the stalled mRNA (which is subsequently degraded). The ribosome the [...]

infB
Probable translation initiation factor if-2 InfB; One of the essential components for the initiation of protein synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis and promotes its binding to the 30S ribosomal subunits. Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex (By similarity); Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. IF-2 subfamily.
