STRINGSTRING
lepB protein (Desulfovibrio vulgaris Hildenborough) - STRING interaction network
"lepB" - Signal peptidase I in Desulfovibrio vulgaris Hildenborough
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

lepBSignal peptidase I; Identified by similarity to SP-P26844; match to protein family HMM PF00461; Belongs to the peptidase S26 family (199 aa)    
Predicted Functional Partners:
lepA
Elongation factor 4; 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 (601 aa)
   
   
  0.909
secY
Protein translocase subunit SecY; 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 (437 aa)
   
   
  0.861
yidC
Membrane protein insertase YidC; 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 (534 aa)
 
 
  0.794
polA
DNA polymerase I; Identified by similarity to SP-P00582; match to protein family HMM PF00476; match to protein family HMM PF01367; match to protein family HMM PF02739; match to protein family HMM TIGR00593 (1015 aa)
   
   
  0.747
DVU_1012
Hemolysin-type calcium-binding repeat protein; Identified by match to protein family HMM PF00092; match to protein family HMM PF00353; match to protein family HMM TIGR01612 (3038 aa)
         
  0.658
secA
Protein translocase subunit SecA; 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 (833 aa)
   
 
 
  0.653
ffh
Signal recognition particle protein; 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 componen [...] (508 aa)
   
   
  0.610
ftsY
Signal recognition particle receptor FtsY; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Acts as a receptor for the complex formed by the signal recognition particle (SRP) and the ribosome-nascent chain (RNC). Interaction with SRP-RNC 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 (488 aa)
   
   
  0.600
lspA
Lipoprotein signal peptidase; This protein specifically catalyzes the removal of signal peptides from prolipoproteins; Belongs to the peptidase A8 family (165 aa)
 
   
  0.596
secG
Preprotein translocase, SecG subunit; Identified by similarity to SP-P33582; match to protein family HMM PF03840 (116 aa)
