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

bchEMg-protoporphyrin IX monomethyl ester oxidative cyclase 66 kD subunit; Involved in the tetrapyrrole biosynthetic pathways leading to chlorophyll and bacteriochlorophyll (BChl). Catalyzes the anaerobic formation of the isocyclic ring (E-ring) in Mg-protoporphyrin monomethyl ester (MPE) to yield protochlorophyllide a (PChlide a) via a six-electron oxidation and the formation of an oxo group at position C13 using oxygen from a water molecule. (499 aa)    
Predicted Functional Partners:
sll1214
Magnesium-protoporphyrin IX monomethyl ester [oxidative] cyclase 1; 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.

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.
  
  
 0.986
chlM
Mg-protoporphyrin IX methyl transferase; Converts Mg-protoporphyrin IX to Mg-protoporphyrin IX methylester using S-adenosyl-L-methionine as a cofactor.
  
 
 0.982
pcr
Protochlorophyllide oxido-reductase; Phototransformation of protochlorophyllide (Pchlide) to chlorophyllide (Chlide).
     
 0.980
slr1923
ORF_ID:slr1923; hypothetical protein.
  
  
 0.960
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.
  
 
 0.878
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.
  
 
 0.852
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.
  
  
 0.827
hisF
Cyclase; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit (By similarity).
     
 0.819
hemF
Coproporphyrinogen III oxidase; Involved in the heme and chlorophyll biosynthesis. Catalyzes the aerobic oxidative decarboxylation of propionate groups of rings A and B of coproporphyrinogen-III to yield the vinyl groups in protoporphyrinogen-IX.
