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

ribABFused GTP cyclohydrolase II and 3,4-dihydroxy-2-butanone 4-phosphate synthase; Catalyzes the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate; In the N-terminal section; belongs to the DHBP synthase family. (398 aa)    
Predicted Functional Partners:
ribH
6,7-dimethyl-8-ribityllumazine 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. Is able to use the non-natural R enantiomer of 3,4- dihydroxy-2-butanone 4-phosphate as a substrate, but with less efficiency than the natural S enantiomer. Cannot use unphosphorylated 3,4-dihydroxy-2-butanone, 3,4-dihydroxy-2-butanone 3-phosphate or diacetyl as substrates.
 
 0.999
ribE
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.
 
 0.999
ribD
Fused 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 C-terminal section; belongs to the HTP reductase family.
 0.999
folEA
GTP cyclohydrolase I; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the GTP cyclohydrolase I family.
  
 
 0.972
ypzK
Putative acetyltransferase; Involved in riboflavin biosynthesis.
  
  
 0.957
folEB
GTP cyclohydrolase I; Converts GTP to 7,8-dihydroneopterin triphosphate. Belongs to the GTP cyclohydrolase IV family.
     
 0.923
ribC
Bifunctional riboflavin kinase FAD synthase; Catalyzes the phosphorylation of riboflavin to FMN followed by the adenylation of FMN to FAD.
 
   
 0.922
fliG
Flagellar motor switching and energizing component; One of the proteins that forms a switch complex that is proposed to be located at the base of the basal body. This complex interacts with chemotaxis proteins (such as CheY) in addition to contacting components of the motor that determine the direction of flagellar rotation; Belongs to the FliG family.
    
 
 0.911
moaA
Molybdenum cofactor biosynthesis protein A; Catalyzes the cyclization of GTP to (8S)-3',8-cyclo-7,8- dihydroguanosine 5'-triphosphate (By similarity). Required for both nitrate assimilation and respiration.
    
 0.906
ndk
Nucleoside diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
  
 0.902
