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

ribFBifunctional riboflavin kinase/FAD synthetase; Catalyzes the phosphorylation of riboflavin to FMN followed by the adenylation of FMN to FAD; Belongs to the RibF family. (313 aa)    
Predicted Functional Partners:
ribC
Riboflavin synthase, alpha subunit; 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.
  
 
 0.986
ribE
Riboflavin synthase beta chain; 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.
  
  
 0.975
truB
tRNA pseudouridine synthase B; Responsible for synthesis of pseudouridine from uracil-55 in the psi GC loop of transfer RNAs; Belongs to the pseudouridine synthase TruB family. Type 1 subfamily.
 
  
 0.951
ribD
Diaminohydroxyphosphoribosylaminopyrimidine deaminase; 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 N-terminal section; belongs to the cytidine and deoxycytidylate deaminase family.
 
  
 0.944
ybjI
5-amino-6-(5-phospho-D-ribitylamino)uracil phosphatase; Catalyzes the dephosphorylation of 5-amino-6-(5-phospho-D- ribitylamino)uracil, and thus could be involved in the riboflavin biosynthesis pathway. Is also able to dephosphorylate flavin mononucleotide (FMN), erythrose 4-phosphate and other phosphoric acid esters. Belongs to the HAD-like hydrolase superfamily. Cof family.
   
 0.917
ileS
isoleucyl-tRNA synthetase; Catalyzes the attachment of isoleucine to tRNA(Ile). As IleRS can inadvertently accommodate and process structurally similar amino acids such as valine, to avoid such errors it has two additional distinct tRNA(Ile)-dependent editing activities. One activity is designated as 'pretransfer' editing and involves the hydrolysis of activated Val-AMP. The other activity is designated 'posttransfer' editing and involves deacylation of mischarged Val-tRNA(Ile).
 
 
 0.916
yigB
5-amino-6-(5-phospho-D-ribitylamino)uracil phosphatase; Catalyzes the dephosphorylation of 5-amino-6-(5-phospho-D- ribitylamino)uracil, and thus could be involved in the riboflavin biosynthesis pathway. Is also able to dephosphorylate flavin mononucleotide (FMN) and other phosphoric acid esters. YigB is important for the formation of dormant persister cells. Belongs to the HAD-like hydrolase superfamily.
  
 
 0.915
yaaY
Uncharacterized protein.
  
  
 0.914
cmk
Cytidylate kinase; ATP, dATP, and GTP are equally effective as phosphate donors. CMP and dCMP are the best phosphate acceptors. Belongs to the cytidylate kinase family. Type 1 subfamily.
 
  
 0.913
ssuE
NAD(P)H-dependent FMN reductase; Catalyzes an NADPH-dependent reduction of FMN, but is also able to reduce FAD or riboflavin.
    
 0.911
