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

ribCRiboflavin synthase alpha chain; ORF_ID:sll0300. (226 aa)    
Predicted Functional Partners:
ribH
Riboflavin synthase beta subunit; Catalyzes the formation of 6,7-dimethyl-8-ribityllumazine by condensation of 5-amino-6-(D-ribitylamino)uracil with 3,4-dihydroxy-2- butanone 4-phosphate. This is the penultimate step in the biosynthesis of riboflavin.
 
 0.999
ribA
GTP cyclohydrolase II; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; In the N-terminal section; belongs to the DHBP synthase family.
 
 0.999
ribG
Riboflavin biosynthesis protein; Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'- phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'- phosphate; In the N-terminal section; belongs to the cytidine and deoxycytidylate deaminase family.
  
 0.999
slr1882
Bifunctional riboflavin kinase/FMN adenylyltransferase; Catalyzes the phosphorylation of riboflavin to FMN followed by the adenylation of FMN to FAD.
  
 
 0.987
slr1694
Activator of photopigment and puc expression; ORF_ID:slr1694.
      
 0.979
hisI
phosphoribosyl-ATP pyrophosphohydrolase:phosphoribosyl-AMP cyclohydrolase; ORF_ID:slr0608; In the C-terminal section; belongs to the PRA-PH family.
  
    0.804
rpl31
50S ribosomal protein L31; Binds the 23S rRNA; Belongs to the bacterial ribosomal protein bL31 family. Type A subfamily.
   
    0.722
slr0876
ORF_ID:slr0876; hypothetical protein.
   
    0.722
slr0326
ORF_ID:slr0326; unknown protein.
       0.560
hitB
Iron utilization protein; ORF_ID:slr0327.
       0.428
