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.

ribH6,7-dimethyl-8-ribityllumazine synthase, 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. (183 aa)    
Predicted Functional Partners:
ribA
GTP cyclohydrolase II / 3,4-dihydroxy-2-butanone 4-phosphate synthase; 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
ribC
Riboflavin synthase alpha chain.
 
 0.999
ribD
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 C-terminal section; belongs to the HTP reductase family.
 
 0.996
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.
 
 
 0.943
ribG
Putative riboflavin-specific deaminase.
 
 
 0.851
cce_0540
Fmu, rRNA SAM-dependent methyltransferase; Specifically methylates the cytosine at position 967 (m5C967) of 16S rRNA.
  
  
 0.820
rpl21
50s ribosomal protein L21; This protein binds to 23S rRNA in the presence of protein L20; Belongs to the bacterial ribosomal protein bL21 family.
   
    0.820
pyrB
Aspartate carbamoyltransferase; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
  
    0.802
nusB
Transcription termination factor, 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.
  
  
 0.798
rpl13
50S ribosomal protein L13; This protein is one of the early assembly proteins of the 50S ribosomal subunit, although it is not seen to bind rRNA by itself. It is important during the early stages of 50S assembly.
   
    0.767
