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 C; Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes; Belongs to the CcmC/CycZ/HelC family. (249 aa)    
Predicted Functional Partners:
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.
 0.999
SAMN02949497_4706
Heme 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.
 
 0.999
ccmA
Cytochrome c biogenesis ATP-binding export 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.

SAMN02949497_1023
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.

SAMN02949497_4714
Cytochrome c biogenesis protein CcmG, thiol:disulfide interchange protein DsbE.
 
  
 0.945
SAMN02949497_4715
Cytochrome c-type biogenesis protein; Possible subunit of a heme lyase.

SAMN02949497_1025
Cytochrome c-type biogenesis protein CcmF.
 
  
 0.879
nuoC
NADH-quinone oxidoreductase subunit C/D; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient; In the C-terminal section; belongs to the complex I 49 kDa subunit family.

SAMN02949497_4716
Cytochrome c-type biogenesis protein CcmH.
 
  
 0.867
cysG
Uroporphyrinogen-III C-methyltransferase; Multifunctional enzyme that catalyzes the SAM-dependent methylations of uroporphyrinogen III at position C-2 and C-7 to form precorrin-2 via precorrin-1. Then it catalyzes the NAD-dependent ring dehydrogenation of precorrin-2 to yield sirohydrochlorin. Finally, it catalyzes the ferrochelation of sirohydrochlorin to yield siroheme. Belongs to the precorrin methyltransferase family. In the N-terminal section; belongs to the precorrin-2 dehydrogenase / sirohydrochlorin ferrochelatase family.
