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

chlHMg-chelatase subunit; ORF_ID:slr1055. (1331 aa)    
Predicted Functional Partners:
chlD
Mg chelatase subunit; Involved in chlorophyll biosynthesis; introduces a magnesium ion into protoporphyrin IX to yield Mg-protoporphyrin IX.
 
 0.999
chlI
Mg chelatase subunit; Involved in chlorophyll biosynthesis; introduces a magnesium ion into protoporphyrin IX to yield Mg-protoporphyrin IX.
 
 
 0.999
chlM
Mg-protoporphyrin IX methyl transferase; Converts Mg-protoporphyrin IX to Mg-protoporphyrin IX methylester using S-adenosyl-L-methionine as a cofactor.
 
 
 0.999
hemH
Ferrochelatase; Catalyzes the ferrous insertion into protoporphyrin IX. Belongs to the ferrochelatase family.
   
 
 0.973
cobN-2
CobN protein; ORF_ID:sll1890.
 
   
 0.962
slr1790
Protoporphyrinogen IX oxidase; Catalyzes the oxidation of protoporphyrinogen IX to protoporphyrin IX. Is involved in the biosynthesis of tetrapyrrole molecules like heme and chlorophyll. Does not use oxygen or artificial electron acceptors such as menadione or benzoquinone. Is functionally coupled with coproporphyrinogen III oxidase (CPO). Is essential for growth.
     
 0.961
sll1091
43 kD bacteriochlorophyll synthase subunit; Catalyzes the stepwise hydrogenation of geranylgeraniol to phytol during chlorophyll A (ChlA) biosynthesis.
  
  
 0.958
chlG
Chlorophyll a synthase; ORF_ID:slr0056.
 
  
 0.949
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.
 
  
 0.865
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.
