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

Score
scuAAssembly factor BSco of the Cu(A) site of cytochrome c oxidase; Necessary for insertion of copper into the active site of cytochrome c oxidase. May play a role in copper homeostasis or redox signaling; Belongs to the SCO1/2 family. (193 aa)    
Predicted Functional Partners:
ctaC
Cytochrome caa3 oxidase (subunit II); Subunits I and II form the functional core of the enzyme complex. Electrons originating in cytochrome c are transferred via heme a and Cu(A) to the binuclear center formed by heme a3 and Cu(B).
 
 
 0.961
yozB
Putative integral inner membrane protein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pm: putative membrane component.
  
 0.961
ctaG
Cytochrome aa(3) assembly factor; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type f: factor.
 
  
 0.924
ytkA
Putative lipoprotein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type lp: lipoprotein.
 
  
 0.903
yvkN
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
      
 0.888
qoxA
Cytochrome aa3-600 quinol oxidase (subunit II); Catalyzes quinol oxidation with the concomitant reduction of oxygen to water. Major component for energy conversion during vegetative growth. Subunit II transfers the electrons from a quinol to the binuclear center of the catalytic subunit I (By similarity).
  
 
 0.822
ctaA
heme-A synthase; Catalyzes the oxidation of the C8 methyl side group on heme O porphyrin ring into a formyl group. Also involved in the sporulation.
 
 
 0.813
ykuV
Thiol-disulfide isomerase; Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions.
 
 
 0.790
yusE
Putative thiol-disulfide oxidoreductase with thioredoxin domain; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
  
 
 0.763
slp
Small peptidoglycan-associated lipoprotein; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type s: structure.
  
 
 0.736
