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, subunit beta (ribE); 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. (143 aa)    
Predicted Functional Partners:
ribA
GTP cyclohydrolase II (ribA-1); Catalyzes the conversion of GTP to 2,5-diamino-6- ribosylamino-4(3H)-pyrimidinone 5'-phosphate (DARP), formate and pyrophosphate; In the N-terminal section; belongs to the DHBP synthase family.
 
 
 0.999
ribB
GTP cyclohydrolase II (ribA-2); Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate.
 
 
 0.999
ribC
Riboflavin synthase (ribC); Similar to GB:L77117 PID:1591811 percent identity: 53.33; identified by sequence similarity; putative; Belongs to the DMRL synthase family.
 
  
  0.967
AF_2007
Riboflavin-specific deaminase (ribG); Catalyzes an early step in riboflavin biosynthesis, the NADPH-dependent reduction of the ribose side chain of 2,5-diamino-6- ribosylamino-4(3H)-pyrimidinone 5'-phosphate, yielding 2,5-diamino-6- ribitylamino-4(3H)-pyrimidinone 5'-phosphate.
 
 
 0.950
pyrD
Dihydroorotase dehydrogenase (pyrD); Catalyzes the conversion of dihydroorotate to orotate with NAD(+) as electron acceptor; Belongs to the dihydroorotate dehydrogenase family. Type 1 subfamily.
  
  
 0.948
trkA
TRK potassium uptake system protein (trkA-2); Part of a potassium transport system.
  
  
 0.910
AF_2129
Aspartate aminotransferase (aspB-2); Similar to PID:1146246 SP:P53001 GB:AL009126 percent identity: 45.38; identified by sequence similarity; putative.
  
 
 0.858
pyrB
Aspartate carbamoyltransferase, catalytic subunit (pyrB); Similar to GB:L77117 PID:1500476 percent identity: 60.74; identified by sequence similarity; putative.
  
    0.848
rpl13
LSU ribosomal protein L13P (rpl13P); 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.
  
    0.804
ribL
Glycerol-3-phosphate cytidyltransferase (taqD); Catalyzes the transfer of the AMP portion of ATP to flavin mononucleotide (FMN) to produce flavin adenine dinucleotide (FAD) coenzyme.
