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

ccsBCytochrome c-type biogenesis protein CcsB; Required during biogenesis of c-type cytochromes (cytochrome c6 and cytochrome f) at the step of heme attachment. (345 aa)    
Predicted Functional Partners:
ccsB-2
ResB family protein; Required during biogenesis of c-type cytochromes (cytochrome c6 and cytochrome f) at the step of heme attachment.
 
  
 0.964
hemD
uroporphyrinogen-III synthase HemD; Catalyzes cyclization of the linear tetrapyrrole, hydroxymethylbilane, to the macrocyclic uroporphyrinogen III.
 
    0.853
AFW94484.1
uroporphyrinogen-III C-methyltransferase; Belongs to the precorrin methyltransferase family.
  
    0.825
AFW93548.1
Hypothetical protein.
  
  
 0.744
AFW93008.1
Cytochrome C biogenesis protein.
  
  
 0.729
txlA
Thiol-disulfide interchange protein TxlA.
  
  
 0.716
petB
Cytochrome b6 subunit PetB; Component of the cytochrome b6-f complex, which mediates electron transfer between photosystem II (PSII) and photosystem I (PSI), cyclic electron flow around PSI, and state transitions.
  
  
 0.599
hemA
glutamyl-tRNA reductase; Catalyzes the NADPH-dependent reduction of glutamyl-tRNA(Glu) to glutamate 1-semialdehyde (GSA).
 
  
 0.565
atpF
ATP synthase F0 subunit B; Component of the F(0) channel, it forms part of the peripheral stalk, linking F(1) to F(0); Belongs to the ATPase B chain family.
  
  
 0.543
psbF
Cytochrome b559 subunit beta; This b-type cytochrome is tightly associated with the reaction center of photosystem II (PSII). PSII is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation. It consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation. Belongs to the PsbE/PsbF family.
