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

ribHRiboflavin synthase; 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. (156 aa)    
Predicted Functional Partners:
ribAB
GTP cyclohydrolase II; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; Belongs to the DHBP synthase family.
 
 
 0.999
ribE
Riboflavin synthase alpha chain (EC 2.5.1.9). Riboflavin synthase is a bifunctional enzyme complex catalyzing the formation of riboflavin from 5-amino-6-(1-D)- ribityl-amino-24(1H3H)-pyrimidinedione and L-34-dihydrohy-2- butanone-4-phosphate via 67-dimethyl-8-lumazine. The alpha subunit catalyzes the dismutation of 67-dimethyl-8-lumazine to riboflavin and 5-amino-6-(1-D)-ribityl-amino-24(1H3H)- pyrimidinedione. ribE: riboflavin synthase alpha subunit; High confidence in function and specificity.
 
 0.999
ribD
AMP deaminase / 5-amino-6-(5-phosphoribosylamino)uracil reductase; 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.
 
 0.997
nusB
Putative 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.
 
  
 0.984
ribF
Riboflavin kinase / FMN adenylyltransferase; Riboflavin biosynthesis protein ribF [Includes: Riboflavin kinase (EC 2.7.1.26) (Flavokinase); FMN adenylyltransferase (EC 2.7.7.2) (FAD pyrophosphorylase) (FAD synthetase)]. ribF: riboflavin biosynthesis protein R; High confidence in function and specificity; Belongs to the ribF family.
 
 
 0.956
ribA
RibA protein; Probable GTP cyclohydrolase II. TIGRFAM: ribA: GTP cyclohydrolase II; Function unclear.
  
 
 0.944
metK
Methionine adenosyltransferase; 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.
  
 
 0.884
azo3766
Conserved hypothetical protein. Homology to blr7238 of B.japonicum of 48% (trembl:Q89E49). No domains predicted. No TMHs. Signal peptide with a probability of 0.570.
  
 
 0.876
mscL
Large-conductance mechanosensitive channel; Channel that opens in response to stretch forces in the membrane lipid bilayer. May participate in the regulation of osmotic pressure changes within the cell.
  
  
 0.864
pyrB
Aspartate carbamoyltransferase (Aspartate transcarbamylase) (Carbamylaspartotranskinase) (ATCase); High confidence in function and specificity; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
