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

lspALipoprotein signal peptidase (Prolipoprotein signal peptidase) (Signal peptidase II) (SPase II); This protein specifically catalyzes the removal of signal peptides from prolipoproteins; Belongs to the peptidase A8 family. (148 aa)    
Predicted Functional Partners:
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.

CAJ68778.1
Putative lipoprotein signal peptidase.
   
 
  0.901
CAJ69486.1
Putative pseudouridylate synthase, RluC/RluD family; Responsible for synthesis of pseudouridine from uracil. Belongs to the pseudouridine synthase RluA family.
  
    0.897
SecY
Preprotein translocase SecY subunit; The central subunit of the protein translocation channel SecYEG. Consists of two halves formed by TMs 1-5 and 6-10. These two domains form a lateral gate at the front which open onto the bilayer between TMs 2 and 7, and are clamped together by SecE at the back. The channel is closed by both a pore ring composed of hydrophobic SecY resides and a short helix (helix 2A) on the extracellular side of the membrane which forms a plug. The plug probably moves laterally to allow the channel to open. The ring and the pore may move independently.

CAJ68422.1
Putative peptidylprolyl isomerase; Experimentally verified as part of mature spore proteome PMID:19542279.
  
  
 0.653
CAJ68215.1
Putative peptidyl-prolyl isomerase; Experimentally verified as part of mature spore proteome PMID:19542279.
  
  
 0.645
ileS
Isoleucyl-tRNA synthetase; 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 2 subfamily.
  
  
 0.643
secA1
Protein translocase subunit SecA1; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane; Belongs to the SecA family.
     
 0.608
pyrR
Bifunctional protein PyrR [Includes: Pyrimidine operon regulatory protein; Regulates transcriptional attenuation of the pyrimidine nucleotide (pyr) operon by binding in a uridine-dependent manner to specific sites on pyr mRNA. This disrupts an antiterminator hairpin in the RNA and favors formation of a downstream transcription terminator, leading to a reduced expression of downstream genes. Belongs to the purine/pyrimidine phosphoribosyltransferase family. PyrR subfamily.
  
    0.588
secG
Protein-export membrane protein SecG; Involved in protein export. Participates in an early event of protein translocation; Belongs to the SecG family.
