摘要:The present invention relates to a novel synthesis method for acyl-pantetheine derivatives. The present invention further relates to the use of said synthesized acyl-pantetheine derivatives as a starting material in the enzymatic synthesis of acyl-coenzyme A derivatives. According to a first aspect thereof, the present invention provides a method for the synthesis of acyl-pantetheine derivatives, the method including the steps of: a) providing a source of pantetheine; b) providing a source of acyl ester; and c) contacting the source of pantetheine with the source of acyl ester to form the corresponding acyl-pantetheine derivative, having the general formula (I), wherein R is an acyl group.The present invention also provides a method for the synthesis of acyl-coenzyme A derivatives as well as the use of a source of pantetheine and a source of acyl ester in the preparation steps of these two methods.

摘要:The present invention provides engineered polypeptides that are useful for the asymmetric synthesis of β-hydroxy-α-amino acids under industrial-relevant conditions. The engineered polypeptides disclosed in this invention were developed through directed evolution based on the ability of catalytic synthesis of (2S, 3R)-2-amino-3-hydroxy-3-(4-nitrophenyl) propanoic acid. The present disclosure also provides polynucleotides encoding engineered polypeptides, host cells capable of expressing engineered polypeptides, and methods of producing β-hydroxy-α-amino acids using engineered polypeptides. Compared to other processes of preparation, the use of the engineered polypeptides of the present invention for the preparation of β-hydroxy-α-amino acids results in high purity of the desired stereoisomers, mild reaction conditions, low pollution and low energy consumption. So, it has good industrial application prospects.

标 题:Method for the solid-phase synthesis of retro-inverso polypeptides
摘要:This invention relates to a method for the solid-phase synthesis of polypeptides containing retro-inverted peptide bonds, using polydimethylacrylamide-co-acryloylsarcosimethylester resin cross-linked with N, N min -ethylene-bis-acrylamide as the insoluble support for lengthening the polypeptide chain in stages by the addition of suitable amino acid derivatives and/or peptides in succession. In particular, the method described in the present invention allows the easy preparation, on the polymer matrix, of monoacylated gem-diamino residues using the reagent I, I-bis (trifluoroacetoxy) iodobenzene in mixed aqueous-organic solvents.

摘要:Disclosed is a new catalyst composition comprising a bimetallic Co—Ru catalyst complexed with a N-heterocylcic ligand that is effective, economical, and provides improvements in oxidative stability in the one step synthesis of 1,3-propanediol (1,3-PDO) from ethylene oxide and synthesis gas. For example, cobalt-ruthenium-2,2′-bipyrimidine, 2,2′-dipyridyl, or 2,4,6-tripridyl-s-triazine catalyst precursors in cyclic ether solvents, such as 1,3-dioxolane, 1,4-dioxolane, 1,4-dioxane, and 2-ethyl-2-methyl-1,3-dioxolane, provide good yields of 1,3-PDO in a one step synthesis.
