STRINGSTRING
RIB5 protein (Saccharomyces cerevisiae) - STRING interaction network
"RIB5" - Riboflavin synthase in Saccharomyces cerevisiae
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

RIB5Riboflavin synthase; catalyzes the last step of the riboflavin biosynthesis pathway; Catalyzes the dismutation of two molecules of 6,7- dimethyl-8-ribityllumazine, resulting in the formation of riboflavin and 5-amino-6-(D-ribitylamino)uracil (238 aa)    
Predicted Functional Partners:
RIB4
Lumazine synthase (6,7-dimethyl-8-ribityllumazine synthase, also known as DMRL synthase); catalyzes synthesis of immediate precursor to riboflavin; 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 (169 aa)
  0.998
RIB3
3,4-dihydroxy-2-butanone-4-phosphate synthase (DHBP synthase), required for riboflavin biosynthesis from ribulose-5-phosphate, also has an unrelated function in mitochondrial respiration; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate (208 aa)
 
  0.997
RIB1
GTP cyclohydrolase II; catalyzes the first step of the riboflavin biosynthesis pathway; Catalyzes the conversion of GTP to 2,5-diamino-6- ribosylamino-4(3H)-pyrimidinone 5’-phosphate (DARP), formate and pyrophosphate (345 aa)
 
  0.994
FMN1
Riboflavin kinase, phosphorylates riboflavin to form riboflavin monophosphate (FMN), which is a necessary cofactor for many enzymes; localizes to microsomes and to the mitochondrial inner membrane; Catalyzes the phosphorylation of riboflavin (vitamin B2) to form flavin mononucleotide (FMN) coenzyme (218 aa)
   
  0.981
RIB2
Bifunctional enzyme with DRAP deaminase and tRNA-pseudouridine synthase activity; the deaminase catalyzes the third step in riboflavin biosynthesis and the synthase catalyzes formation of pseudouridine at position 32 in cytoplasmic tRNAs; Responsible for synthesis of pseudouridine from uracil- 32 in cytoplasmic transfer RNAs (591 aa)
   
  0.953
RIB7
Diaminohydroxyphoshoribosylaminopyrimidine deaminase; catalyzes the second step of the riboflavin biosynthesis pathway; 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 (244 aa)
 
  0.949
YGL117W
Putative protein of unknown function (265 aa)
     
        0.858
TPS1
Synthase subunit of trehalose-6-phosphate synthase/phosphatase complex, which synthesizes the storage carbohydrate trehalose; also found in a monomeric form; expression is induced by the stress response and repressed by the Ras-cAMP pathway; Synthase catalytic subunit of the trehalose synthase complex that catalyzes the production of trehalose from glucose-6- phosphate and UDP-glucose in a two step process. Can function independently of the complex (495 aa)
           
  0.760
HIS4
Multifunctional enzyme containing phosphoribosyl-ATP pyrophosphatase, phosphoribosyl-AMP cyclohydrolase, and histidinol dehydrogenase activities; catalyzes the second, third, ninth and tenth steps in histidine biosynthesis (799 aa)
   
   
  0.758
URA2
Bifunctional carbamoylphosphate synthetase/aspartate transcarbamylase; catalyzes the first two enzymatic steps in the de novo biosynthesis of pyrimidines; both activities are subject to feedback inhibition by UTP; This protein is a "fusion" protein encoding three enzymatic activities of the pyrimidine pathway (GATase, CPSase, and ATCase) (2214 aa)
