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, beta subunit; 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. (154 aa)    
Predicted Functional Partners:
ribA
Riboflavin biosynthesis protein ribA; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; In the C-terminal section; belongs to the GTP cyclohydrolase II family.
 
 0.999
ribB
RibB protein; High confidence in function and specificity.
 
 0.999
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 C-terminal section; belongs to the HTP reductase family.
 
 0.999
ribC
Riboflavin kinase / FMN adenylyltransferase; Riboflavin biosynthesis protein [Includes: Riboflavin kinase (EC 2.7.1.26) (Flavokinase); FMN adenylyltransferase (EC 2.7.7.2) (FAD pyrophosphorylase) (FAD synthetase)]; High confidence in function and specificity; Belongs to the ribF family.

llmg_1914
Hypothetical protein; Cof-subfamily: Cof-like hydrolase TIGRFAM00099; Conserved hypothetical protein.
     
 0.982
ribU
Conserved hypothetical protein; Mediates riboflavin uptake, may also transport FMN and roseoflavin (By similarity). Probably a riboflavin-binding protein that interacts with the energy-coupling factor (ECF) ABC-transporter complex. Unlike classic ABC transporters this ECF transporter provides the energy necessary to transport a number of different substrates. The substrates themselves are bound by transmembrane, not extracytoplasmic soluble proteins. Uptake of riboflavin into proteosomes containing EcfA1A2T and RibU has been demonstrated. Uptake requires hydrolyzable Mg-ATP; Belongs to [...]
   
  
 0.896
folE
Bifunctional protein folE [Includes: 2-amino-4-hydroxy-6- hydroxymethyldihydropteridine pyrophosphokinase (EC 2.7.6.3) (7,8 dihydro-6-hydroxymethylpterin-pyrophosphokinase) (HPPK) (6- hydroxymethyl-7,8-dihydropterin pyrophosphokinase) (PPPK); GTP cyclohydrolase I (EC 3.5.4.16) (GTP-CH-I)]; High confidence in function and specificity; In the C-terminal section; belongs to the GTP cyclohydrolase I family.
     
 0.859
metK
MetK protein; 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.
  
 
 0.788
folP
Dihydropteroate synthase; High confidence in function and specificity.
  
  
 0.760
mscL
Large-conductance mechanosensitive channel protein; 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.
