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

rifKAHBA synthase; Catalyzes the dehydration and aromatization of 5-amino-5- deoxy-3-dehydroshikimate (aminoDHS) to 3-amino-5-hydroxybenzoate (AHBA), a compound that then serves as the starter unit for the assembly of a polyketide during the biosynthesis of rifamycin B and other ansamycin antibiotics. Cannot utilize 5-deoxy-5-amino-3- dehydroquinate (aminoDHQ), 5-deoxy-5-aminoshikimate (aminoSA), quinate, 3-dehydroquinate, or 3-dehydroshikimate (DHS) as substrate. (388 aa)    
Predicted Functional Partners:
rifL
Oxidoreductase RifL; In a complex with RifK, RifL may catalyze the oxidation of UDP-glucose to UDP-3-keto-D-glucose, which would then be used by RifK to produce UDP-kanosamine. Is not able to use dTDP-glucose as substrate.
 
 
 0.991
RifM
COG0637 Predicted phosphatase/phosphohexomutase.
 
  
 0.972
aroQ
3-dehydroquinate dehydratase; Catalyzes a trans-dehydration via an enolate intermediate. Belongs to the type-II 3-dehydroquinase family.
    
 0.928
RifA
Rifamycin polyketide synthase; COG0318 Acyl-CoA synthetases (AMP-forming)/AMP-acid ligases II.

rifG
Aminodehydroquinate synthase; May catalyze the conversion of 3,4-dideoxy-4-amino-D-arabino- heptulosonate 7-phosphate (aDAHP) to 5-deoxy-5-amino-3-dehydroquinate (aDHQ). Probably involved in the formation of 3-amino-5-hydroxybenzoic acid (AHBA), the precursor of rifamycin and related ansamycins. Belongs to the sugar phosphate cyclases superfamily. aDHQS family.
