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

ccmAATP binding protein of heme exporter A; Part of the ABC transporter complex CcmAB involved in the biogenesis of c-type cytochromes; once thought to export heme, this seems not to be the case, but its exact role is uncertain. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. CcmA exporter (TC 3.A.1.107) family. (205 aa)    
Predicted Functional Partners:
ccmC
Heme exporter protein C; Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes; Belongs to the CcmC/CycZ/HelC family.
 
 0.999
ccmB
Heme exporter protein B, cytochrome c-type biogenesis protein; Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes; Belongs to the CcmB/CycW/HelB family.
 0.999
ccmD
Heme exporter protein C; Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes; Belongs to the CcmD/CycX/HelD family.
 
 
 
 0.992
ccmE
Cytochrome c biogenesis, possible subunit of a heme lyase; Heme chaperone required for the biogenesis of c-type cytochromes. Transiently binds heme delivered by CcmC and transfers the heme to apo-cytochromes in a process facilitated by CcmF and CcmH. Belongs to the CcmE/CycJ family.
 
 
 0.987
ccmH
Possible subunit of heme lyase; Possible subunit of a heme lyase.
 
   
 0.983
ccmF
Cytochrome c-type biogenesis protein; Residues 1 to 647 of 647 are 99.69 pct identical to residues 1 to 647 of 647 from Escherichia coli K-12 Strain MG1655: B2196.
 
   
 0.982
dsbE
Disulfide oxidoreductase (in biogenesis of cytochrome c; Involved in disulfide bond formation. Catalyzes a late, reductive step in the assembly of periplasmic c-type cytochromes, probably the reduction of disulfide bonds of the apocytochrome c to allow covalent linkage with the heme. Possible subunit of a heme lyase (By similarity); Belongs to the thioredoxin family. DsbE subfamily.
 
   
 0.964
napB
Cytochrome c-type protein; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB; Belongs to the NapB family.
 
    0.830
nrfF
Part of formate-dependent nitrite reductase complex; Not required for the biosynthesis of any of the c-type cytochromes. Possible subunit of a heme lyase; Belongs to the CcmH/CycL/Ccl2/NrfF family.
 
   
 0.829
napC
Cytochrome c-type protein; Mediates electron flow from quinones to the NapAB complex.
 
  
 0.828
