Excision of a Protein-Derived Amine for <i>p</i>-Aminobenzoate Assembly by the Self-Sacrificial Heterobimetallic Protein CADD

BIOCHEMISTRY, 62(22), 3276–3282.

TL;DR: Turnover studies using limiting O2 have identified a para-aminobenzaldehyde metabolic intermediate that is formed on the path to pABA formation and use of pABCHO and other probe substrates shows that the heterobimetallic Fe/Mn form of the enzyme is capable of oxygen insertion to generate the pA BA-carboxylate.

Self-sacrificial tyrosine cleavage by an Fe:Mn oxygenase for the biosynthesis of para-aminobenzoate in Chlamydia trachomatis

PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA, 119(39).

author keywords: folate biosynthesis; radical transfer; spectroscopy; heterobinuclear cluster
MeSH headings : Bacterial Proteins / metabolism; Chlamydia trachomatis / enzymology; Folic Acid; Iron / metabolism; Manganese / metabolism; Oxygen / metabolism; Oxygenases / metabolism; Tyrosine / metabolism; para-Aminobenzoates / metabolism
TL;DR: High in vitro activity relies on the stoichiometric addition of both Fe and Mn, and CADD is shown to activate O2 to self-sacrificially produce pABA from Tyr27. (via Semantic Scholar)
