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

lepBSignal peptidase I, family S26; The type-1 signal peptidase (SPase I; also known as leader peptidase I) is a serine protease that removes the signal peptides from the majority of exported pre-proteins. SPase I is an integral membrane protein that is anchored in the cytoplasmic membrane by four N-terminal transmembrane segments with the main part of the protein protuding in the periplasmic space; Contains an additional C-terminal transmembrane segments; Belongs to family 26 (clan SF) of serine peptidases (S26), S26A subfamily; High confidence in function and specificity. (566 aa)    
Predicted Functional Partners:
CAZ97811.1
Conserved hypothetical periplasmic protein; Contains a signal peptide cleaved between the residues 19 and 20; Localized in the periplasmic space; Conserved hypothetical protein.

secD
Protein-export membrane protein secD; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. SecDF uses the proton motive force (PMF) to complete protein translocation after the ATP-dependent function of SecA; Belongs to the SecD/SecF family. SecD subfamily.

CAZ96608.1
This membrane protein seems involved in the insertion of outer membrane proteins. It has two domains. The C-terminal part, a beta-barrel pore-forming region inserted in the outer membrane, is a Bacterial surface antigen (D15) domain. The N-terminal part, exposed in the periplasm, and involved in gating of the pore and binding of the substrate proteins consists of four Surface antigen variable number repeats; Belongs to the surface antigen D15 family; Signal peptide cleaved between the residues 24 and 25; Localized in the outer membrane; Family membership.

lepA
Elongation factor 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.

CAZ97848.1
Conserved hypothetical periplasmic protein; Contains a signal peptide cleaved between the residues 20 and 21; Localized in the periplasmic space; Conserved hypothetical protein.

moeA2
Molybdopterin biosynthesis protein; Catalyzes the insertion of molybdate into adenylated molybdopterin with the concomitant release of AMP. Belongs to the MoeA family.
       0.680
oxaA
Inner membrane protein oxaA; 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.

rnhB
Ribonuclease HII; Endonuclease that specifically degrades the RNA of RNA-DNA hybrids.
  
  
 0.657
rpoN
RNA polymerase sigma-54; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. sigma-54 factors consist of three distinct regions: A conserved N-terminal glutamine-rich region (50 aa) that contains a potential leucine zipper motif. A region which is not conserved. A conserved C-terminal region (350 aa) that contains a second potential leucine zipper, a potential DNA-binding 'helix-turn-helix' motif and a perfectly conserved octapeptide whose function is not known; Localized in the cytoplasm; High confidenc [...]
