We report a chemo-biocatalytic cascade for the synthesis of substituted pyrroles, driven by the action of an irreversible, thermostable, pyridoxal 5'-phosphate (PLP)-dependent, C-C bond-forming biocatalyst ( Th AOS). The Th AOS catalyzes the Claisen-like condensation between various amino acids and acyl-CoA substrates to generate a range of α-aminoketones. These products are reacted with β-keto esters in an irreversible Knorr pyrrole reaction. The determination of the 1.6 Å resolution crystal structure of the PLP-bound form of Th AOS lays the foundation for future engineering and directed evolution. This report establishes the AOS family as useful and versatile C-C bond-forming biocatalysts.
