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

sync_2014Signal peptidase I; Identified by match to protein family HMM PF00717; match to protein family HMM TIGR02227; Belongs to the peptidase S26 family. (257 aa)    
Predicted Functional Partners:
minE
Cell division topological specificity factor MinE; Prevents the cell division inhibition by proteins MinC and MinD at internal division sites while permitting inhibition at polar sites. This ensures cell division at the proper site by restricting the formation of a division septum at the midpoint of the long axis of the cell.

lepB
Signal peptidase I; Identified by match to protein family HMM PF00717; match to protein family HMM TIGR02227; Belongs to the peptidase S26 family.
 
  
0.931
lepA
GTP-binding protein LepA; Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back-translocation proceeds from a post-translocation (POST) complex to a pre- translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP- dependent manner.
  
 
 0.922
tuf
Translation elongation factor Tu; This protein promotes the GTP-dependent binding of aminoacyl- tRNA to the A-site of ribosomes during protein biosynthesis.
   
  
 0.788
rnhB
Ribonuclease HII; Endonuclease that specifically degrades the RNA of RNA-DNA hybrids; Belongs to the RNase HII family.
  
  
 0.769
alaS
alanyl-tRNA synthetase; 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.
  
  
 0.755
sync_2573
Conserved hypothetical protein TIGR01777; Identified by match to protein family HMM PF01370; match to protein family HMM TIGR01777.
   
    0.737
sync_0374
Identified by match to protein family HMM PF00575; match to protein family HMM TIGR00757.
 
    0.717
gyrA-1
DNA gyrase subunit A; Identified by match to protein family HMM PF00521; match to protein family HMM PF03989.
  
  
 0.694
gyrA-2
DNA gyrase, A subunit; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to modulate DNA topology and maintain chromosomes in an underwound state. Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings. Type II topoisomerases break and join 2 DNA strands simultaneously in an ATP-dependent manner.
