PRODUCTION OF FRUCTOSE FROM OLIGO-/ AND/OR POLYSACCHARIDES
The present invention relates to a method for converting at least one oligo- and/or polysaccharide into fructose comprising the steps of: a) adding to a composition comprising water, phosphate and at least one oligo- and/or polysaccharide at least four enzymes, and b) subsequently enzymatically converting the at least one oligo- and/or polysaccharide to fructose in the presence of the at least four enzymes, wherein in step a) at least one additional saccharide is added, whereby the at least one additional saccharide is selected from the group consisting of saccharides comprising 20 or less monosaccharide residues and/or combinations thereof; wherein in step a) the at least four enzymes, preferably at least five enzymes, are selected from the group consisting of transferases, phosphorylases, mutases, isomerases, hydrolases, phosphatases and combinations thereof; and wherein at least one enzyme in step a) is a phosphatase.
NON-CALORIC SWEETENERS AND METHODS FOR SYNTHESIZING
Disclosed are steviol glycosides referred to as rebaudioside V and rebaudioside W. Also disclosed are methods for producing rebaudioside M (Reb M), rebausoside G (Reb G), rebaudioside KA (Reb KA), rebaudioside V (Reb V) and rebaudioside (Reb W).
Engineered glucosyltransferases
Disclosed herein are glucosyltransferases with modified amino acid sequences. Such engineered enzymes exhibit improved alpha-glucan product yields and/or lower leucrose yields, for example. Further disclosed are reactions and methods in which engineered glucosyltransferases are used to produce alpha-glucan.
BUCKWHEAT-DERIVED C-GLYCOSYLTRANSFERASE GENE AND UTILIZATION THEREOF
Transgenic plants with blue flower color, or their inbred or outbred progeny, or their propagules, partial plant bodies, tissues or cells, are provided. A buckwheat-derived C-glucosyltransferase (CGT) gene or its homolog is transferred into a host plant to cause delphinidin-type anthocyanins and flavone mono-C-glycosides to be copresent in the plant cells.
Method for Efficient Biosynthesis of Reb D by Glycosyltransferase
The disclosure discloses a method for efficient biosynthesis of Reb D by glycosyltransferase, belonging to the field of biocatalytic synthesis. According to the disclosure, a glycosyltransferase having an activity to catalyze synthesis of Reb D from Reb A is obtained, and a mutant YojK-I241T/G327N with high catalytic activity is obtained through directed evolution. The glycosyltransferase mutant YojK-I241T/G327N and a sucrose synthase AtSuSy derived from Arabidopsis thaliana are used for constructing a coupling reaction to realize efficient catalytic synthesis of Reb D with Reb A as a substrate. The reaction is carried out by using 19.32 g/L (20 mmol/L) of Reb A as the substrate for 15 h to efficiently synthesize 20.59 g/L of Reb D, and the yield of Reb D reaches 91.29%, which provides an efficient and green new pathway for production of Reb D.
GLUCURONOSYLTRANSFERASE, GENE ENCODING SAME AND METHOD FOR USING THE SAME
Glucuronosyltransferase 1 gene which catalyzes glucuronic acid transfer to the hydroxyl group at the 3-position in an oleanane-type triterpenoid is identified. Glucuronosyltransferase 1 gene having a desired activity, derived from a Fabaceae plant (soybean, Glycyrrhiza, and Lotus japonicus), and containing nucleotide sequences represented by SEQ ID Nos: 2, 4, and 6, respectively, is provided.
PEANUT MILK PRODUCT WITH SUPERIOR PEANUT TASTE, AROMA AND TO IMPROVE GUT MICROBIOTA AND PREPARATION PROCESS AND USE THEREOF
Disclosed herein is a process for producing a peanut milk product, which includes subjecting a milk material to a hydrolysis reaction with lactase and transglucosidase to obtain a milk product, immersing peanut kernels in water to obtain swelled peanut kernels, subjecting the swelled peanut kernels to a steam cooking treatment to obtain steamed peanut kernels, and admixing the milk product with the steamed peanut kernels, followed by subjecting a mixture thus obtained to a heating treatment, so as to obtain the peanut milk product. A method for improving gut health using the peanut milk product and a canned food containing the peanut milk product are also disclosed.
