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.

lspASignal peptidase II; This protein specifically catalyzes the removal of signal peptides from prolipoproteins; Belongs to the peptidase A8 family. (164 aa)    
Predicted Functional Partners:
ileS
isoleucine--tRNA ligase; Catalyzes the attachment of isoleucine to tRNA(Ile). As IleRS can inadvertently accommodate and process structurally similar amino acids such as valine, to avoid such errors it has two additional distinct tRNA(Ile)-dependent editing activities. One activity is designated as 'pretransfer' editing and involves the hydrolysis of activated Val-AMP. The other activity is designated 'posttransfer' editing and involves deacylation of mischarged Val-tRNA(Ile). Belongs to the class-I aminoacyl-tRNA synthetase family. IleS type 1 subfamily.

ispH
4-hydroxy-3-methylbut-2-enyl diphosphate reductase; Catalyzes the conversion of 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate (HMBPP) into a mixture of isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). Acts in the terminal step of the DOXP/MEP pathway for isoprenoid precursor biosynthesis. Belongs to the IspH family.

lepB
Signal peptidase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the peptidase S26 family.
      
 0.809
lnt
Acyltransferase; Catalyzes the phospholipid dependent N-acylation of the N- terminal cysteine of apolipoprotein, the last step in lipoprotein maturation; Belongs to the CN hydrolase family. Apolipoprotein N- acyltransferase subfamily.
     
 0.639
ribF
FMN adenylyltransferase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the ribF family.
 
  
 0.634
ffh
Signal recognition particle; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY. Interaction with FtsY leads to the transfer of the RNC complex to the Sec translocase for insertion into the membrane, the hydrolysis of GTP by both Ffh and FtsY, and the dissociation of the SRP-FtsY complex into the individual components; Belo [...]
     
 0.609
lgt
Prolipoprotein diacylglyceryl transferase; Catalyzes the transfer of the diacylglyceryl group from phosphatidylglycerol to the sulfhydryl group of the N-terminal cysteine of a prolipoprotein, the first step in the formation of mature lipoproteins; Belongs to the Lgt family.
 
  
 0.609
murJ
Multidrug transporter MurJ; Involved in peptidoglycan biosynthesis. Transports lipid- linked peptidoglycan precursors from the inner to the outer leaflet of the cytoplasmic membrane.
 
   
 0.588
yidC
Insertase; Required for the insertion and/or proper folding and/or complex formation of integral membrane proteins into the membrane. Involved in integration of membrane proteins that insert both dependently and independently of the Sec translocase complex, as well as at least some lipoproteins. Aids folding of multispanning membrane proteins.
   
  
 0.585
secE
Preprotein translocase subunit SecE; Essential subunit of the Sec protein translocation channel SecYEG. Clamps together the 2 halves of SecY. May contact the channel plug during translocation; Belongs to the SecE/SEC61-gamma family.
