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

ribHRiboflavin synthase beta chain (6,7-dimethyl-8-ribityllumazine synthase); 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; Belongs to the DMRL synthase family. (156 aa)    
Predicted Functional Partners:
ribA
Riboflavin biosynthesis protein RibA; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; In the C-terminal section; belongs to the GTP cyclohydrolase II family.
 
 
 0.999
ribE
Riboflavin synthase subunit alpha.
 
 0.999
ribD
Riboflavin biosynthesis protein RibD; 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 C-terminal section; belongs to the HTP reductase family.

Lwor_2400
GTP cyclohydrolase II.
 
 
 0.972
nusB
Hypothetical protein; Involved in transcription antitermination. Required for transcription of ribosomal RNA (rRNA) genes. Binds specifically to the boxA antiterminator sequence of the ribosomal RNA (rrn) operons.
  
  
 0.941
ribF
Riboflavin biosynthesis protein RibF (riboflavin kinase/FMN adenylyltransferase); Belongs to the ribF family.
  
  
 0.937
metK
S-adenosylmethionine synthetase; Catalyzes the formation of S-adenosylmethionine (AdoMet) from methionine and ATP. The overall synthetic reaction is composed of two sequential steps, AdoMet formation and the subsequent tripolyphosphate hydrolysis which occurs prior to release of AdoMet from the enzyme.
  
 
 0.933
Lwor_2399
Putative biotin synthetase like protein.
  
 
 0.921
mscL
Large conductance mechanosensitive channel; Channel that opens in response to stretch forces in the membrane lipid bilayer. May participate in the regulation of osmotic pressure changes within the cell.
   
  
 0.912
pyrB
Aspartate carbamoyltransferase; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
  
    0.889
