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

hepSHeptaprenyl diphosphate synthase component I; Supplies heptaprenyl diphosphate, the precursor for the side chain of the isoprenoid quinone menaquinone-7 (MQ-7). (251 aa)    
Predicted Functional Partners:
hepT
Heptaprenyl diphosphate synthase component II; Supplies heptaprenyl diphosphate, the precursor for the side chain of the isoprenoid quinone menaquinone-7 (MQ-7). Belongs to the FPP/GGPP synthase family.
 
 
 0.999
menH
Menaquinone methyltransferase; Methyltransferase required for the conversion of demethylmenaquinol (DMKH2) to menaquinol (MKH2).
 
  
 0.994
ispA
Geranyltranstransferase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; enzyme.
  
 
 0.984
uppS
Undecaprenyl pyrophosphate synthase; Catalyzes the condensation of isopentenyl diphosphate (IPP) with allylic pyrophosphates generating different type of terpenoids.
  
 
 0.926
ylqD
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
  
    0.824
yisP

 0.815
rsiW
anti-sigma(W) factor; The anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-W (SigW). Holds SigW, its cognate ECF sigma factor, in an inactive form until released by regulated intramembrane proteolysis (RIP). SigW and RsiW mediate cell response to cell wall stress. RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut periplasmically (site-1 protease, S1P, PrsW) , then within the membrane itself (site-2 protease, S2P [...]
  
     0.748
mtrB
Tryptophan operon RNA-binding attenuation protein (TRAP); Required for transcription attenuation control in the trp operon. This trans-acting factor binds to trinucleotide repeats (GAG or UAG) located in the trp leader transcript causing transcription termination. Binds the leader RNA only in presence of L-tryptophan. Belongs to the MtrB family.
 
    0.726
spo0B
Sporulation initiation phosphotransferase; Key element in the phosphorelay regulating sporulation initiation. Acts on spo0A. Mediates reversible phosphoryl transfer from spo0F to spo0A.
  
    0.726
dxr
1-deoxy-D-xylulose-5-phosphate reductoisomerase; Catalyzes the NADP-dependent rearrangement and reduction of 1-deoxy-D-xylulose-5-phosphate (DXP) to 2-C-methyl-D-erythritol 4- phosphate (MEP); Belongs to the DXR family.
