Pseudomonas fluorescens 2-79 : 2-amino-4-deoxychorismate synthase Inferred from experiment : phzE

In Pathway: phenazine-1-carboxylate biosynthesis

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.

Mass balance status: Balanced.

Enzyme Commission Primary Name: 2-amino-4-deoxychorismate synthase

Enzyme Commission Synonyms: ADIC synthase, 2-amino-2-deoxyisochorismate synthase, SgcD

Standard Gibbs Free Energy (ΔrG in kcal/mol): -2.0558853 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
Requires Mg2+. The reaction occurs in the reverse direction to that shown above. In contrast to most anthranilate-synthase I (ASI) homologues, this enzyme is not inhibited by tryptophan. The sequential action of this enzyme and EC, 2-amino-4-deoxychorismate dehydrogenase, leads to the formation of the benzoxazolinate moiety of the enediyne antitumour antibiotic C-1027, which is essential for both binding and intercalating the minor groove of DNA [Van08, Yu95b]
