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

AFZ73951.12, 5-diamino-6-hydroxy-4-(5-phosphoribosylamino)pyrimidine 1'-reductase; PFAM: RibD C-terminal domain; TIGRFAM: riboflavin-specific deaminase C-terminal domain; 2,5-diamino-6-hydroxy-4-(5-phosphoribosylamino)pyrimidine 1'-reductase, archaeal. (224 aa)    
Predicted Functional Partners:
AFZ72386.1
PFAM: Lumazine binding domain; TIGRFAM: riboflavin synthase, alpha subunit.
 
  
 0.983
ribB
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.
 
 
 0.954
ribH
6,7-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.
 
 
 0.939
folP-2
Dihydropteroate synthase; PFAM: Pterin binding enzyme; Mur ligase family, glutamate ligase domain; Mur ligase middle domain; TIGRFAM: dihydropteroate synthase; folylpolyglutamate synthase/dihydrofolate synthase.
 
   
 0.761
AFZ73391.1
birA, biotin-(acetyl-CoA-carboxylase) ligase; PFAM: HTH domain; Biotin protein ligase C terminal domain; Biotin/lipoate A/B protein ligase family; TIGRFAM: birA, biotin-[acetyl-CoA-carboxylase] ligase region; BirA biotin operon repressor domain.
  
  
 0.632
AFZ72672.1
Ammonia permease; PFAM: Ammonium Transporter Family; Nitrogen regulatory protein P-II; TIGRFAM: ammonium transporter; Belongs to the P(II) protein family.
     
 0.627
msrA
methionine-S-sulfoxide reductase; Has an important function as a repair enzyme for proteins that have been inactivated by oxidation. Catalyzes the reversible oxidation-reduction of methionine sulfoxide in proteins to methionine.
       0.623
AFZ73950.1
PFAM: Phosphoribulokinase / Uridine kinase family; TIGRFAM: uridine kinase.
  
 
 0.619
thiL
Thiamine-monophosphate kinase; Catalyzes the ATP-dependent phosphorylation of thiamine- monophosphate (TMP) to form thiamine-pyrophosphate (TPP), the active form of vitamin B1; Belongs to the thiamine-monophosphate kinase family.
 
   
 0.565
hisG
ATP phosphoribosyltransferase; Catalyzes the condensation of ATP and 5-phosphoribose 1- diphosphate to form N'-(5'-phosphoribosyl)-ATP (PR-ATP). Has a crucial role in the pathway because the rate of histidine biosynthesis seems to be controlled primarily by regulation of HisG enzymatic activity. Belongs to the ATP phosphoribosyltransferase family. Long subfamily.
