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

BN69_0787Heme 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. (223 aa)    
Predicted Functional Partners:
ccmA
Heme exporter 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.
 0.999
ccmC
Heme exporter protein CcmC; Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes; Belongs to the CcmC/CycZ/HelC family.
 
 0.997
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.
