摘要:Thaxtomins are phytotoxic secondary metabolites produced in plant pathogenic Streptomyces strains and have received considerable interests as bioherbicides. A cell-free, biocombinatorial approach was developed to produce a thaxtomin library for herbicide development. Combination of biosynthetic enzymes led to the production of 136 substituted 2,5-diketopiperazines, thaxtomin D, thaxtomin B and thaxtomin A analogs in a single pot. Furthermore, rational engineering of TxtA allowed the synthesis of azido-containing thaxtomin analog. Selected unnatural thaxtomins demonstrated improved herbicidal activities. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
