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

ho2Heme oxygenase; Catalyzes the opening of the heme ring with the release of iron. Key enzyme in the synthesis of the chromophoric part of the photosynthetic antennae. (250 aa)    
Predicted Functional Partners:
slr0116
Phycocyanobilin:ferredoxin oxidoreductase; Catalyzes the four-electron reduction of biliverdin IX-alpha (2-electron reduction at both the A and D rings); the reaction proceeds via an isolatable 2-electron intermediate, 181,182-dihydrobiliverdin. Belongs to the HY2 family.
 
  
 0.988
bvdR
Biliverdin reductase; ORF_ID:slr1784.
  
  
 0.981
hemN-2
Oxygen independent coprophorphyrinogen III oxidase; Involved in the heme and chlorophyll biosynthesis. Catalyzes the anaerobic oxidative decarboxylation of propionate groups of rings A and B of coproporphyrinogen III to yield the vinyl groups in protoporphyrinogen IX; Belongs to the anaerobic coproporphyrinogen-III oxidase family.
     
 0.942
hemH
Ferrochelatase; Catalyzes the ferrous insertion into protoporphyrin IX. Belongs to the ferrochelatase family.
     
 0.931
AT103
Phytochrome-regulated gene; Catalyzes the formation of the isocyclic ring in chlorophyll biosynthesis. Mediates the cyclase reaction, which results in the formation of divinylprotochlorophyllide (Pchlide) characteristic of all chlorophylls from magnesium-protoporphyrin IX 13-monomethyl ester (MgPMME); Belongs to the AcsF family.
     
 0.926
ho1
Heme oxygenase; Catalyzes the opening of the heme ring with the release of iron. Key enzyme in the synthesis of the chromophoric part of the photosynthetic antennae.
  
  
0.909
bfr
Bacterioferritin; Iron-storage protein, whose ferroxidase center binds Fe(2+) ions, oxidizes them by dioxygen to Fe(3+), and participates in the subsequent Fe(3+) oxide mineral core formation within the central cavity of the protein complex; Belongs to the bacterioferritin family.
     
  0.900
ctaB
Cytochrome c oxidase folding protein; Converts heme B (protoheme IX) to heme O by substitution of the vinyl group on carbon 2 of heme B porphyrin ring with a hydroxyethyl farnesyl side group.
     
  0.900
bfr-2
Bacterioferritin; Iron-storage protein, whose ferroxidase center binds Fe(2+) ions, oxidizes them by dioxygen to Fe(3+), and participates in the subsequent Fe(3+) oxide mineral core formation within the central cavity of the protein complex.
     
  0.900
hemN
Oxygen independent coprophorphyrinogen III oxidase; Probably acts as a heme chaperone, transferring heme to an unknown acceptor. Binds one molecule of heme per monomer, possibly covalently (By similarity). Binds 1 [2Fe-2S] cluster. Although this protein has sequence motifs typically found in proteins binding the [4Fe-4S]-AdoMet radical-SAM cluster and S-adenosylmethionine, spectroscopic evidence suggests that a [2Fe-2S] cluster is present; S- adenosylmethionine was not detected. Has no detectable coproporphyrinogen-III oxidase activity.
