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; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the peptidase S26 family. (259 aa)    
Predicted Functional Partners:
lepA
GTP-binding protein 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.
  
 
 0.947
oxaA
Inner-membrane protein insertion factor 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.
 
  
 0.935
atpE
ATP synthase F0, subunit C; F(1)F(0) ATP synthase produces ATP from ADP in the presence of a proton or sodium gradient. F-type ATPases consist of two structural domains, F(1) containing the extramembraneous catalytic core and F(0) containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation.

pgsA-2
CDP-diacylglycerol--glycerol-3-phosphate 3-phosphatidyltransferase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the CDP-alcohol phosphatidyltransferase class-I family.
 
  
 0.868
rnc
Ribonuclease III; Digests double-stranded RNA. Involved in the processing of primary rRNA transcript to yield the immediate precursors to the large and small rRNAs (23S and 16S). Processes some mRNAs, and tRNAs when they are encoded in the rRNA operon. Processes pre-crRNA and tracrRNA of type II CRISPR loci if present in the organism.
 
  
 0.858
rfaEa
D-beta-D-heptose 7-phosphate kinase, domain I of bifunctional protein HldE; Function of strongly homologous gene; enzyme.
       0.827
kdsB
3-deoxy-D-manno-octulosonate cytidylyltransferase; Activates KDO (a required 8-carbon sugar) for incorporation into bacterial lipopolysaccharide in Gram-negative bacteria.
       0.827
pyrG
CTP synthetase; Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates.
  
    0.807
pgsA
CDP-diacylglycerol-glycerol-3-phosphate 3-phosphatidyltransferase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the CDP-alcohol phosphatidyltransferase class-I family.
 
  
 0.793
lspA
Lipoprotein signal peptidase; This protein specifically catalyzes the removal of signal peptides from prolipoproteins; Belongs to the peptidase A8 family.
