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

ccmCHeme exporter protein CcmC; Identified by similarity to SP:P30962; match to protein family HMM PF01578. (237 aa)    
Predicted Functional Partners:
ccmB
Heme exporter protein CcmB; 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
ccmE
Cytochrome c-type biogenesis protein CcmE; 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.
 
 
 0.997
ccmF
Cytochrome c-type biogenesis protein CcmF; Identified by match to protein family HMM PF01578.
 
  
 0.969
ccmA
Heme ABC exporter, ATP-binding protein CcmA; 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.
 
  
  0.961
dsbE
Thiol:disulfide interchange protein DsbE; Identified by similarity to SP:P33926.
 
  
 0.950
MXAN_6156
Cytochrome c biogenesis protein/thioredoxin; Identified by match to protein family HMM PF00085; match to protein family HMM PF02683.
  
  
 0.862
MXAN_3235
Cytochrome c-type biogenesis protein, CcmH/CycL/Ccl2/NrfF family; Possible subunit of a heme lyase.
 
   
 0.854
MXAN_3255
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.
       0.773
MXAN_3251
Putative membrane protein.
       0.689
hemD
uroporphyrinogen-III synthase; Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III.
  
    0.616
