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

yqhTPutative peptidase YqhT; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the peptidase M24B family. (352 aa)    
Predicted Functional Partners:
mprF
Putative lysylphosphatidylglycerol synthetase/glycosyltransferase; Catalyzes the transfer of a lysyl group from L-lysyl- tRNA(Lys) to membrane-bound phosphatidylglycerol (PG), which produces lysylphosphatidylglycerol (LPG), a major component of the bacterial membrane with a positive net charge. LPG synthesis contributes to bacterial virulence as it is involved in the resistance mechanism against cationic antimicrobial peptides (CAMP) produces by the host's immune system (defensins, cathelicidins) and by the competing microorganisms.
  
    0.790
pepT
Peptidase T(tripeptidase); Cleaves the N-terminal amino acid of tripeptides. Belongs to the peptidase M20B family.
  
 
 0.781
SCA91426.1
Putative hydrolase or acyltransferase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
   
 
 0.771
efp
Elongation factor P; Involved in peptide bond synthesis. Stimulates efficient translation and peptide-bond synthesis on native or reconstituted 70S ribosomes in vitro. Probably functions indirectly by altering the affinity of the ribosome for aminoacyl-tRNA, thus increasing their reactivity as acceptors for peptidyl transferase.
  
 
 0.743
pepV
Beta-Ala-Xaa dipeptidase; Function of strongly homologous gene; enzyme.
 
 
 0.683
pepN
Function experimentally demonstrated in the studied genus; enzyme.
  
 
 0.675
ygjB
Conserved hypothetical protein; Homologs of previously reported genes of unknown function.
 
     0.661
mapA
Methionine aminopeptidase; Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val). Requires deformylation of the N(alpha)-formylated initiator methionine before it can be hydrolyzed; Belongs to the peptidase M24A family. Methionine aminopeptidase type 1 subfamily.
  
  
 0.637
nusB
N utilization substance protein B homolog; Involved in transcription antitermination. Required for transcription of ribosomal RNA (rRNA) genes. Binds specifically to the boxA antiterminator sequence of the ribosomal RNA (rrn) operons.
     
 0.614
pepX
Xaa-Pro dipeptidyl-peptidase; Removes N-terminal dipeptides sequentially from polypeptides having unsubstituted N-termini provided that the penultimate residue is proline; Belongs to the peptidase S15 family.
