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:
some 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

ccmHHolocytochrome c synthetase - thiol:disulfide oxidoreductase ccmh; May be required for the biogenesis of c-type cytochromes. Possible subunit of a heme lyase (350 aa)    
Predicted Functional Partners:
dsbE
Cytochrome c biogenesis protein ccmg, thiol:disulfide interchange protein dsbe; Involved in disulfide bond formation. Catalyzes a late, reductive step in the assembly of periplasmic c-type cytochromes, probably the reduction of disulfide bonds of the apocytochrome c to allow covalent linkage with the heme. Possible subunit of a heme lyase. DsbE is maintained in a reduced state by DsbD
 
  
 0.999
ccmF
Holocytochrome c synthetase membrane subunit ccmf; Required for the biogenesis of c-type cytochromes. Possible subunit of a heme lyase
 
 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
 
 
 0.999
ccmC
Heme trafficking system membrane protein ccmc; Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes
 
  
 0.998
ccmD
Heme trafficking system membrane protein ccmd; Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes
 
  
 0.997
ccmB
Heme trafficking system membrane protein ccmb; Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes
 
  
 0.996
ccmA
Heme trafficking system atp-binding protein; 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
 
  
 0.995
nrfE
Heme lyase (nrfefg) for insertion of heme into c552, subunit nrfe; May be required for the biogenesis of c-type cytochromes. Possible subunit of a heme lyase
 
 0.984
nrfG
Heme lyase (nrfefg) for insertion of heme into c552, subunit nrfg; Required for formate-dependent nitrite reduction. Not required for the biosynthesis of any of the c-type cytochromes nor for the secretion of the periplasmic cytochromes
  
 0.962
napD
Assembly protein for periplasmic nitrate reductase; Chaperone for NapA, the catalytic subunit of the periplasmic nitrate reductase. It binds directly and specifically to the twin- arginine signal peptide of NapA, preventing premature interaction with the Tat translocase and premature export May have a role in the insertion of the NapA molybdenum cofactor
