A method for biosynthesis of adipic acid from six-carbon dicarboxylic acids having 伪, 尾-enoate reductase activity by treatment with an enzyme is provided. The biocatalytic conversion of aliphatic and hydroxycarboxylic acids to corresponding aldehydes, alcohols, and amines using novel carboxylate ...
A mixture of carboxylic acids: citric acid, succinic acid, fumaric acid and malic acid, and any possible combinations thereof. This product is used orally or also intravenously, in the treatment of patients with chronic renal failure, hyperammonemia or human conditions having negative nitrogen balance...
Description uses aliphatic and hydroxybutyric acid the catalyzed conversion of novel carboxylate reductase, aldehyde reductase and transaminase to corresponding aldehyde, alcohols and amine. Additionally provide the genetically engineered microorganism for biosynthetic process. 展开 ...
The invention relates to a process for the biosynthetic production and recovery of [5S,6S]-6-amino-5-hydroxycyclohexa-1 ,3-diene-1-carboxylic acid) catalyzed, at increased enzyme activity, at least by an enzyme belonging to the class of aminodeoxyisochorismate (ADIC) synthases and an enzyme ...
process efficiency RE: recovery RSD: relative standard deviation SA: salicylic acid SAM: S-adenosyl-l-methionine SD: standard deviation SPE: solid-phase extraction tZ: trans-zeatin tZR: trans-zeatin riboside UHPLC: Ultra High Performance Liquid Chromatography ...
Thus, the ESI–MS and 1H NMR spectral data confirmed the potential AMC as 5-butyl-2-pyridine carboxylic acid with a molecular formula of C10H13NO2 (Supplementary Fig. S4e). Phytochemical screening, solubility and thermo-stability of the compound Phytochemical screening of the pure fraction ...
inducedReformatsky reactions(Equation (191)) <93AG(E)1191>. An interesting dehydration of an optically active β-hydroxy acid under retention is shown inScheme 41<69TL1047,87HCA1320>. A similar aldol addition cyclization tandem process has been devised using acyl iron intermediates (Scheme 42) ...
93 The pathway shares the first step with the cyclohexanecarboxylic acid biosynthetic pathway, anti elimination of H6R from (54),94,95 but diverges at the stage of (57). Both (57) and (68) were incorporated into (65), implicating (67a) or its C-1 epimer (67b) as a likely ...
The process of present invention includes the production of dimer of phenazine-1-carboxylic acid natural product by a fluorescent pseudomonad bacterium. The ingredient of “water-based semi-solid media” for initial growth of the bacterium is preferably about 2 to 30 g/L of protease peptone, mos...
With the optimal conditions in hand, we explored the substrate scope of carboxylic acids. As can be seen in Fig.2, this Umpolung amidation has a satisfactory functional group compatibility and a broad carboxylic acid substrate scope. A series of structurally diverse carboxylic acids (1a-1rr) are...
