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

ccmCABC transporter, membrane spanning protein (heme); Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes; Belongs to the CcmC/CycZ/HelC family. (253 aa)    
Predicted Functional Partners:
ccmB
ABC transporter, membrane spanning protein (heme); 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
ccmA
ABC transporter, nucleotide binding/ATPase protein (heme); 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.
 
 0.997
cycJ
Cytochrome-c biosynthesis heme-carrier protein cycJ; 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.
 
 
 0.992
ccmG
Thiol:disulfide interchange protein.
 
  
 0.956
cycK
Cytochrome c-type synthesis protein.
 
  
 0.881
cycL
cycL protein; Possible subunit of a heme lyase.
 
   
 0.871
Atu2689
Conserved hypothetical protein; Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes; Belongs to the CcmD/CycX/HelD family.
       0.801
ccdA
Cytochrome c-type biogenesis protein.
  
  
 0.737
hem4
Uroporphyrinogen III synthase HEM4; Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III.
  
    0.600
fbcB
Ubiquinol-cytochrome c reductase cytochrome b subunit; Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis.
  
  
 0.587
