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

ribH6,7-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. (155 aa)    
Predicted Functional Partners:
ribE
Riboflavin synthase, alpha subunit; Identified by match to protein family HMM PF00677; match to protein family HMM TIGR00187.
 
 0.999
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
ribD
Riboflavin biosynthesis protein RibD; Identified by match to protein family HMM PF00383; match to protein family HMM PF01872; match to protein family HMM TIGR00326.
 
 0.996
nusB
N utilization substance protein B; 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.
  
  
 0.963
metK
Methionine adenosyltransferase; 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.
  
 
 0.880
ribF
Riboflavin biosynthesis protein RibF; Identified by match to protein family HMM PF01687; match to protein family HMM PF06574; match to protein family HMM TIGR00083; Belongs to the ribF family.
  
  
 0.875
mscL
Large conductance mechanosensitive channel protein; 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.
  
  
 0.854
guaB
Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
  
 
 0.821
rplU
Ribosomal protein L21; This protein binds to 23S rRNA in the presence of protein L20; Belongs to the bacterial ribosomal protein bL21 family.
   
    0.817
pyrB
Aspartate carbamoyltransferase; Identified by similarity to SP:Q59711; match to protein family HMM PF00185; match to protein family HMM PF02729; match to protein family HMM TIGR00670; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
