STRING protein interaction network
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:
some 3D structure is known or predicted
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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology
Your Input:
Gene Fusion
ribE6,7-dimethyl-8-ribityllumazine 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:
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
GTP cyclohydrolase-2; Catalyzes the conversion of GTP to 2,5-diamino-6- ribosylamino-4(3H)-pyrimidinone 5'-phosphate (DARP), formate and pyrophosphate
Riboflavin synthase; 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
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
Transcription antitermination protein NusB; 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. The affinity of NusB for the boxA RNA sequence is significantly increased in the presence of the ribosomal protein S10. NusB may serve as a loading factor that ensures efficient entry of S10 into the transcription complexes. It also modulates the rrn boxA-mediated transcription elongation rates
5-amino-6-(5-phospho-D-ribitylamino)uracil phosphatase YbjI; Catalyzes the dephosphorylation of 5-amino-6-(5-phospho- D-ribitylamino)uracil, and thus could be involved in the riboflavin biosynthesis pathway. Is also able to dephosphorylate flavin mononucleotide (FMN), erythrose 4-phosphate and other phosphoric acid esters; Belongs to the HAD-like hydrolase superfamily. Cof family
5-amino-6-(5-phospho-D-ribitylamino)uracil phosphatase YigB; Catalyzes the dephosphorylation of 5-amino-6-(5-phospho- D-ribitylamino)uracil, and thus could be involved in the riboflavin biosynthesis pathway. Is also able to dephosphorylate flavin mononucleotide (FMN) and other phosphoric acid esters. YigB is important for the formation of dormant persister cells; Belongs to the HAD-like hydrolase superfamily
Glutamine--fructose-6-phosphate aminotransferase [isomerizing]; Catalyzes the first step in hexosamine metabolism, converting fructose-6P into glucosamine-6P using glutamine as a nitrogen source
Transcriptional repressor NrdR; Represses transcription of the class Ib RNR genes nrdHIEF but has much smaller effect on transcription of the class Ia RNR genes nrdAB and class III RNR genes nrdDG. By binding to nrdR boxes in the promoter regions to alter promoter activity, nrdR differentially regulates nrdAB, nrdHIEF and nrdD transcription in aerobic growth
Thiamine-monophosphate kinase; Catalyzes the ATP-dependent phosphorylation of thiamine- monophosphate (TMP) to form thiamine-pyrophosphate (TPP), the active form of vitamin B1. Cannot use thiamine as substrate. Is highly specific for ATP as phosphate donor; Belongs to the thiamine-monophosphate kinase family
