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

ccmBHeme exporter protein B; Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes; Belongs to the CcmB/CycW/HelB family. (222 aa)    
Predicted Functional Partners:
ccmA
Heme exporter protein 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.
 0.999
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.
 
 0.998
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. Belongs to the CcmE/CycJ family.
 
 
 0.969
ccmD
Heme exporter protein D; Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes; Belongs to the CcmD/CycX/HelD family.
  
 
 0.937
ccmF
Cytochrome c-type biogenesis protein CcmF; Identified by match to TIGR protein family HMMTIGR00353 InterPro: Cytochrome c-type biogenesis protein (CcmF); High confidence in function and specificity.
 
  
 0.860
dsbE
Thiol:disulfide interchange protein DsbE; Identified by sequence similarity; putative InterPro: Periplasmic protein thiol:disulfide oxidoreductase DsbE; High confidence in function and specificity.
 
  
 0.837
ccmH
Cytochrome C biogenesis protein; Possible subunit of a heme lyase.
 
   
 0.832
blc
Outer membrane lipoprotein Blc, putative; Involved in the storage or transport of lipids necessary for membrane maintenance under stressful conditions. Displays a binding preference for lysophospholipids.
     
 0.559
ABO_0867
Conserved hypothetical protein; (GGDEF family protein) identified by match to PFAM protein family HMMPF00990.
       0.543
ABO_0868
Hypothetical protein.
       0.542
