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

chlH-2Protoporphyrin IX magnesium chelatase; ORF_ID:alr4733. (1228 aa)    
Predicted Functional Partners:
chlD
Mg chelatase subunit; Involved in chlorophyll biosynthesis. Catalyzes the insertion of magnesium ion into protoporphyrin IX to yield Mg-protoporphyrin IX.
 
 0.997
chlI
Protoporphyrin IX magnesium chelatase chain; Involved in chlorophyll biosynthesis; introduces a magnesium ion into protoporphyrin IX to yield Mg-protoporphyrin IX.
 
 
 0.996
alr3201
Mg-protoporphyrin IX methyl transferase; ORF_ID:alr3201.
 
 
 0.980
chlB
Protochlorophyllide reductase ChlB subunit; Component of the dark-operative protochlorophyllide reductase (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This reaction is light-independent. The NB-protein (ChlN-ChlB) is the catalytic component of the complex.
 
  
 0.958
chlN
Protochlorophillide reductase subunit; Component of the dark-operative protochlorophyllide reductase (DPOR) that uses Mg-ATP and reduced ferredoxin to reduce ring D of protochlorophyllide (Pchlide) to form chlorophyllide a (Chlide). This reaction is light-independent. The NB-protein (ChlN-ChlB) is the catalytic component of the complex.
 
  
 0.952
alr3751
Ferrochelatase; Catalyzes the ferrous insertion into protoporphyrin IX. Belongs to the ferrochelatase family.
   
 
 0.942
chlG
Chlorophyll synthase 33 kD subunit; ORF_ID:all4480.
 
  
 0.939
alr4616
ORF_ID:alr4616; similar to ferrochelatase; Belongs to the ferrochelatase family.
  
 
 0.934
chlH
Protoporphyrin IX magnesium chelatase; ORF_ID:all4365; chlH gene product.
  
  
 
0.916
alr5217
ORF_ID:alr5217; hypothetical protein.
