| + | L-4-Chlorokynurenine (L-4-Cl-Kyn) is a neuropharmaceutical drug candidate in development for the treatment of major depressive disorder. Recently, this amino acid was naturally found as a residue in the lipopeptide antibiotic taromycin. Herein we report the unprecedented conversion of L-tryptophan to L-4-Cl-Kyn catalyzed by four enzymes in the taromycin biosynthetic pathway from the marine bacterium Saccharomonospora sp. CNQ-490. We used genetic, biochemical, structural, and analytical techniques to establish L-4-Cl-Kyn biosynthesis, which is initiated by the Tar14 flavin-dependent tryptophan chlorinase and its flavin reductase partner Tar15. This work revealed the first tryptophan 2,3-dioxygenase (Tar13) and kynurenine formamidase (Tar16) enzymes that are selective for chlorinated substrates. The substrate scope of Tar13, 14, and 16 was examined revealing intriguing promiscuity, thereby opening doors for the targeted engineering of these enzymes as useful biocatalysts. | ||
