专利号:US-11447742-B2 优先权日:2016-02-09 标题 :Compositions and methods for activation and overexpression of secondary metabolites in microorganisms 发明人:HAMILL DAKOTA BENJAMIN; COTTER JAKE J 权利人:PROSPECTIVE RES INC 摘要:Methods and compositions herein provide non-naturally occurring γ-butyrolactones (GBLs) in racemic mixtures that increase efficiency and effectiveness of screening for production of antibiotics, and enhance yields and express silent pathways. Non-naturally occurring GBLs were synthesized and found to stimulate antibiotic production in several different streptomycete strains. Antibiotic production by Streptomyces coelicolor was induced by a racemic mixture of non-cognate stereoisomers of VB-D, seven of which are non-naturally occurring. Further, novel A-factor-type GBL analogs stimulated antibiotic production in S. coelicolor . Synthesis in response to the treatment with the non-cognates GBL was observed for known compounds including undecylprodigiosin, desferrioxamine and streptorubin B, as was synthesis of a compound of unknown structure. A group of 37 additional microbial strains was screened by principal component analysis to determine optimal concentrations of each of a panel of four non-cognate synthetic GBLs for addition to cultures with optimal stimulation of secondary metabolites, and large scale fermentations were analyzed and product enhancement by the GBLs was observed.

专利号:US-10655153-B2 优先权日:2017-03-14 标 题 :Chemoenzymatic synthesis of peptide beta-lactones and beta-hydroxy acids 发明人:WENCEWICZ TIMOTHY A; SCHAFFER JASON E; RECK MARGARET R 权利人:WENCEWICZ TIMOTHY A; SCHAFFER JASON E; RECK MARGARET R; UNIV WASHINGTON 摘要:Methods of producing peptide beta-lactones and beta-hydroxy acids are disclosed that include contacting a beta-hydroxy-alpha-amino acid, an aryl carrier protein (ObiD), and ATP with a non-ribosomal protein synthetase. A continuous flow reactor is disclosed that includes an elongate conduit with at least one region that includes a first region with a non-ribosomal protein synthetase immobilized to a substrate. The non-ribosomal protein synthetase of the continuous flow reactor is configured to contact a flow of a reaction mixture that includes a beta-hydroxy-alpha-amino acid and an aryl carrier protein. The non-ribosomal protein synthetase is further configured to release a peptide beta-lactone into the flow of the reaction mixture.
