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

pufMPufM, photosynthetic reaction center M subunit; The reaction center is a membrane-bound complex that mediates the initial photochemical event in the electron transfer process of photosynthesis. (308 aa)    
Predicted Functional Partners:
pufX
Intrinsic membrane pufX protein; Associated with the reaction center - light-harvesting complex I. May play a critical role in facilitating the interaction between this complex and other components required for light-driven cyclic electron transfer; Belongs to the PufX family.
  
 0.999
pufL
PufL, Photosynthetic reaction center L subunit; The reaction center is a membrane-bound complex that mediates the initial photochemical event in the electron transfer process of photosynthesis.
 
0.999
pufA
LHI alpha, Light-harvesting B875 protein; Antenna complexes are light-harvesting systems, which transfer the excitation energy to the reaction centers.
 
 0.999
puhA
Reaction centre H protein; The reaction center is a membrane-bound complex that mediates the initial photochemical event in the electron transfer process of photosynthesis.
  
 0.999
pufB
LHI beta, Light-harvesting B875 subunit; Antenna complexes are light-harvesting systems, which transfer the excitation energy to the reaction centers.
 
 
 0.999
bchX
Chlorophyllide reductase, BchX subunit; Converts chlorophylls (Chl) into bacteriochlorophylls (BChl) by reducing ring B of the tetrapyrrole.
 
  
 0.981
RSP_0292
Hypothetical protein; IMG reference gene:2512955299.
  
    0.973
bchM
Mg-protoporphyrin IX methyltransferase; IMG reference gene:2512955296; PFAM: Methyltransferase small domain; Magnesium-protoporphyrin IX methyltransferase C-terminus; TIGRFAM: magnesium protoporphyrin O-methyltransferase.
  
  
 0.955
pufQ
Protein pufQ; Required for bacteriochlorophyll biosynthesis. Directly involved in the assembly of both the B875 and B800-850 pigment-protein complexes.
  
  
 0.953
bchL
Ferredoxin protochlorophyllide reductase subunit L; 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 L component serves as a unique electron donor to the NB-component of the complex, and binds Mg-ATP.
