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.

ribB3,4-dihydroxy-2-butanone 4-phosphate synthase (ribB); Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate. (215 aa)    
Predicted Functional Partners:
ribD
Riboflavin biosynthesis protein (ribD); 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.
 0.999
ribH
Riboflavin synthase, beta chain (ribH); 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; Belongs to the DMRL synthase family.
 
 
 0.999
ribE
Riboflavin synthase, alpha chain (ribE); 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.
 
 0.998
ribA
GTP cyclohydrolase II (ribA); Catalyzes the conversion of GTP to 2,5-diamino-6- ribosylamino-4(3H)-pyrimidinone 5'-phosphate (DARP), formate and pyrophosphate; Belongs to the GTP cyclohydrolase II family.
  
 0.993
HI_0765
Lipooligosaccharide biosynthesis protein; Similar to GB:M37913 GB:L19441 PID:1573535 percent identity: 26.32; identified by sequence similarity; putative; Belongs to the glycosyltransferase 25 family.
       0.737
folE
GTP cyclohydrolase I (folE); Similar to GB:U00007 SP:P27511 GB:X63910 PID:312964 PID:405902 percent identity: 63.93; identified by sequence similarity; putative.
     
 0.610
HI_0755
Conserved hypothetical protein; Similar to SP:P37691 PID:912478 GB:U00096 PID:1790043 percent identity: 41.83; identified by sequence similarity; putative; To E.coli YibQ.
      
 0.579
birA
Biotin operon repressor/biotin acetyl coenzyme A carboxylase synthetase (birA); Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a biotin-operon repressor. In the presence of ATP, BirA activates biotin to form the BirA-biotinyl-5'-adenylate (BirA-bio-5'-AMP or holoBirA) complex. HoloBirA can either transfer the biotinyl moiety to the biotin carboxyl carrier protein (BCCP) subunit of acetyl-CoA carboxylase, or bind to the biotin operator site and inhibit transcription of the operon.
     
 0.528
folK
2-amino-4-hydroxy-6- hydroxymethyldihydropteridine-pyrophosphokinase (folK); Similar to GB:D26562 SP:P26281 GB:L06495 PID:146013 PID:473801 percent identity: 56.33; identified by sequence similarity; putative.
    
 0.512
nadR
Transcriptional regulator (nadR); This enzyme has two activities: nicotinamide mononucleotide (NMN) adenylyltransferase and ribosylnicotinamide (RN) kinase. The RN kinase activity catalyzes the phosphorylation of RN to form nicotinamide ribonucleotide. The NMN adenylyltransferase activity catalyzes the transfer of the AMP moiety of ATP to nicotinamide ribonucleotide to form NAD(+); In the C-terminal section; belongs to the bacterial RNK family.
