A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 2.6.1.85

Accepted Name
Aminodeoxychorismate synthase.
Alternative Name(s)
4-amino-4-deoxychorismate synthase.
ADC synthase.
Reaction catalysed
Chorismate + L-glutamine <=> 4-amino-4-deoxychorismate + L-glutamate
Cofactor(s)
Mg(2+).
Comment(s)
  • Composed of two subunits, PabA and PabB.
  • In the absence of PabA and glutamine, PabB converts ammonia and chorismate into 4-amino-4-deoxychorismate.
  • PabA converts glutamine into glutamate only in the presence of stoichiometric amounts of PabB.
  • Coupled with EC 4.1.3.38, to form 4-aminobenzoate.
  • Formerly EC 6.3.5.8.
