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

smpBProbable SSRA-binding protein SmpB; 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 th [...] (160 aa)    
Predicted Functional Partners:
rplP
50S ribosomal protein L16 RplP; Binds 23S rRNA and is also seen to make contacts with the A and possibly P site tRNAs; Belongs to the universal ribosomal protein uL16 family.
  
 
 0.983
rplS
50S ribosomal protein L19 RplS; 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.
 
 
 0.981
ftsE
Cell division ATP-binding protein FtsE; Part of the ABC transporter FtsEX involved in cellular division. Has ATPase activity.
  
  
 0.979
rplT
50S ribosomal protein L20 RplT; Binds directly to 23S ribosomal RNA and is necessary for the in vitro assembly process of the 50S ribosomal subunit. It is not involved in the protein synthesizing functions of that subunit (By similarity).
 
 
 0.972
rpsB
Rv2890c, (MTCY274.21c), len: 287 aa. rpsB, 30s ribosomal protein s2, equivalent to O33038|RS2_MYCLE|RPSB|ML1598|MLCB250.63 30S ribosomal protein S2 from Mycobacterium leprae (277 aa), FASTA scores: opt: 1593, E(): 2.3e-93, (91.5% identity in 270 aa overlap). Also highly similar to others e.g. O31212|RS2_STRCO|RPSB|SC2E1.41 from Streptomyces coelicolor (310 aa), FASTA scores: opt: 1302, E(): 6.1e-75, (70.6% identity in 289 aa overlap); Q9KA63|RPSB|BH2427 from Bacillus halodurans (244 aa), FASTA scores: opt: 991, E(): 2.3e-55, (59.6% identity in 255 aa overlap); P21464|RS2_BACSU|RPSB fro [...]
 
 
 0.971
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.
  
 
 0.970
rpsC
30S ribosomal protein S3 RpsC; Binds the lower part of the 30S subunit head. Binds mRNA in the 70S ribosome, positioning it for translation; Belongs to the universal ribosomal protein uS3 family.
  
 
 0.970
rplM
50S ribosomal protein L13 RplM; This protein is one of the early assembly proteins of the 50S ribosomal subunit, although it is not seen to bind rRNA by itself. It is important during the early stages of 50S assembly.
 
 
 0.969
rplB
50S ribosomal protein L2 RplB; One of the primary rRNA binding proteins. Required for association of the 30S and 50S subunits to form the 70S ribosome, for tRNA binding and peptide bond formation. It has been suggested to have peptidyltransferase activity; this is somewhat controversial. Makes several contacts with the 16S rRNA in the 70S ribosome. Belongs to the universal ribosomal protein uL2 family.

rpmA
Rv2441c, (MTCY428.05), len: 86 aa. rpmA, 50S ribosomal proteins L27, equivalent to Q9CBZ3|RL27_MYCLE from Mycobacterium leprae (88 aa), FASTA scores: opt: 504,E(): 7.6e-28, (93.2% identity in 81 aa overlap). Also highly similar to others e.g. P95757|RL27_STRGR from Streptomyces griseus (85 aa), FASTA scores: opt: 442, E(): 1.2e-23, (81.5% identity in 81 aa overlap); etc. Contains PS00831 Ribosomal protein L27 signature. Belongs to the L27P family of ribosomal proteins.
