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

ribA/ribBPossible GTP cyclohydrolase II / 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 C-terminal section; belongs to the GTP cyclohydrolase II family. (577 aa)    
Predicted Functional Partners:
ribE
Putative Riboflavin synthase alpha chain; Citation: Eberhardt et al. (1996) Eur. J. Biochem. 242:712-719; Alternative locus ID: PMED4_04891.
 
 0.999
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 C-terminal section; belongs to the HTP reductase family.
 0.999
ribH
Putative 6,7-dimethyl-8-ribityllumazine synthase or 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.
