RESUMO
The UbiX/UbiD system is widespread in microbes and responsible for the reversible decarboxylation of unsaturated carboxylic acids. The UbiD enzyme catalyzes this unusual reaction using a prenylated flavin (prFMN) as cofactor, the latter formed by the flavin prenyltransferase UbiX. A detailed picture of the biochemistry of flavin prenylation, oxidative maturation, and covalent catalysis underpinning reversible decarboxylation is emerging. This reveals the prFMN cofactor can undergo a wide range of transformations, complemented by considerable UbiD-variability. These provide a blueprint for biotechnological applications aimed at producing hydrocarbons or aromatic C-H activation through carboxylation.
