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

VC_2054Heme 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. (68 aa)    
Predicted Functional Partners:
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.
 
 
 0.994
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.
 
 
 0.978
VC_2056
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.
 
 
 0.976
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.
 
 
 
 0.953
VC_2052
Cytochrome c-type biogenesis protein CcmF; Similar to GB:L42023 SP:P45037 PID:1006386 PID:1221212 PID:1205344; identified by sequence similarity; putative.
 
  
 0.920
dsbE
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 (By similarity); Belongs to the thioredoxin family. DsbE subfamily.
 
  
 0.904
VC_2040
Conserved hypothetical protein; Identified by Glimmer2; putative; Belongs to the UPF0352 family.
  
     0.699
seqA
seqA protein; Negative regulator of replication initiation, which contributes to regulation of DNA replication and ensures that replication initiation occurs exactly once per chromosome per cell cycle. Binds to pairs of hemimethylated GATC sequences in the oriC region, thus preventing assembly of replication proteins and re- initiation at newly replicated origins. Repression is relieved when the region becomes fully methylated.
  
     0.648
VC_1271
Hypothetical protein; Identified by Glimmer2; putative.
  
     0.630
VC_1099
Conserved hypothetical protein; Identified by Glimmer2; putative.
  
     0.622
