摘要:The present invention discloses a computer-implemented method for engineering fluorinase enzymes towards the synthesis of fluorophenyl compounds. Limited or no mechanistic details of fluorinase enzymes have hindered progress in understanding their catalytic mechanisms for synthesizing synthetic organofluorine compounds. Through a comprehensive computational screening process, specific methionine-sulfonium phenyl substrates, including [(3S)-3-amino-3-carboxypropyl][2,5-difluoro-4-(4-methoxy-2,4-dioxobutyl)phenyl]methylsulfonium, were designed and optimized using quantum chemical optimization techniques. This methodology uncovers crucial information on F— ion attack conformation and the catalytic mechanism of the substrate, leading to the formation of Methyl 3-oxo-4-(2,4,5-trifluorophenyl)butanoate. Furthermore, a protein sequence and 3D modeling-based enzyme screening process was employed to identify the most suitable enzyme for this substrate. The identified enzyme was then engineered using the mechanistic insights gained from the studies, resulting in improved substrate scope, stability and catalytic efficiency. This computer-based approach offers an efficient and precise alternative to traditional trial-and-error methods, advancing the field towards the successful synthesis fluorophenyl compounds.

标题 :Bio-intermediates for use in the chemical synthesis of polyketides
发明人：SANTI DANIEL; ASHLEY GARY; MYLES DAVID C
摘要:The present invention relates to compounds made by a subset of modules from one or more polyketide synthase (“PKSâ€?) genes that are used as starting material in the chemical synthesis of novel molecules, particularly naturally occurring polyketides or derivatives thereof. The biologically derived intermediates (“bio-intermediatesâ€?) generally represent particularly difficult compounds to synthesize using traditional chemical approaches due to one or more stereocenters. In one aspect of the invention, an intermediate in the synthesis of epothilone is provided that feeds into the synthetic protocol of Danishefsky and co-workers. In another aspect of the invention, intermediates in the synthesis of discodermolide are provided that feed into the synthetic protocol of Smith and co-workers. By taking advantage of the inherent stereochemical specificity of biological processes, the syntheses of key intermediates and thus the overall syntheses of compounds like epothilone and discodermolide are greaty simplified.

摘要:The invention herein disclosed provides for methods for the synthesis of polymers from monomers. In particular the method provides for the synthesis of polynucleotides from mononucleotides in the absence of catalytic enzymes. The method comprises providing an aqueous solution having a plurality of phospholipid molecules and monomer molecules; subjecting the aqueous solution to fluctuating temperature conditions; subjecting the aqueous solution to fluctuating cycles of drying and hydrating conditions; subjecting the aqueous solution to fluctuating [H + ] conditions; the fluctuating conditions thereby allowing formation of a chemical bond between at least two monomers to create a polymer. The invention is of particular use in the fields of molecular biology, structural biology, cell biology, molecular switches, molecular circuits, and molecular computational devices, and the manufacture thereof.

摘要:Synthesis of enantiopure cis-α-irone from a renewable carbon source Disclosed herein are natural and synthetic enzymes capable of performing a method of producing cis-α-irone. The method comprises providing an enzyme capable of converting psi-ionone to cis-α-irone; and contacting the enzyme and psi-ionone under suitable conditions to produce cis-α-irone. The enzyme may be a methyltransferase from Streptomyces albireticuli (SaMT), a promiscuous bifunctional methyltransferase/cyclase (pMT1) enzyme from Streptomyces, or a modified pMT1 enzyme with at least one substitution. The enzymes allow the in-vivo and in-vitro production of cis-α-irone including the use of glucose as feedstock for the biotransformation into cis-α-irone.
