Úloha F420H2-závislých reduktas v biosyntéze bioaktivních mikrobiálních metabolitů inkorporujících 4-alkyl-L-prolinový derivát / The role of F₄₂₀H₂-dependent reductases in the biosynthesis of microbial bioactive metabolites incorporating a 4-alkyl-˪-proline derivateSteiningerová, Lucie January 2020 (has links)
Antitumor pyrrolobenzodiazepines (PBDs), lincosamide antibiotics, quorum sensing molecule hormaomycin, and antituberculotic griselimycin are structurally and functionally diverse groups of actinobacterial metabolites. The common feature of these compounds is the incorporation of L-tyrosine- or L-leucine-derived 4-alkyl-L-proline derivatives (APDs) in their structures. APD biosynthesis involves a set of up to six homologous proteins. According to their proposed order in the biosynthesis of 4-propyl-L-proline, a model APD of lincosamide lincomycin, the homologous proteins were named Apd1 - Apd6. Here, we report that the last reaction in the biosynthetic pathway of APDs, catalyzed by F420H2-dependent Apd6 reductases, contributes to the structural diversity of APD precursors. Specifically, the heterologous overproduction and in vitro tests of six Apd6 enzymes demonstrated that Apd6 from the biosynthesis of PBDs and hormaomycin can reduce only an endocyclic imine double bond, whereas Apd6 LmbY and partially GriH from the biosyntheses of lincomycin and griselimycin, respectively, also reduce the more inert exocyclic double bond of the same 4-substituted Δ1 -pyrroline-2-carboxylic acid substrate, making LmbY and GriH unusual, if not unique, among reductases. The two successive F420H2-dependent reduction...
