Production of Steviol Glycosides in Recombinant Hosts
The invention relates to recombinant microorganisms and methods for producing steviol glycosides and steviol glycoside precursors.
Production of steviol glycosides in recombinant hosts
The invention relates to recombinant microorganisms and methods for producing steviol glycosides and steviol glycoside precursors.
STEVIOL GLYCOSIDE PRODUCTION
The present invention relates to a method for increasing the degree of glycosylation of a composition comprising steviol glycosides, which method comprises:
a. contacting said composition comprising steviol glycosides with a recombinant microorganism, a cell free extract derived from such a microorganism or an enzyme preparation derived from either thereof; and b. thereby to increase the degree of glycosylation of the composition comprising steviol glycosides, wherein the recombinant microorganism comprises one or more nucleotide sequence(s) encoding: a polypeptide having ent-copalyl pyrophosphate synthase activity;a polypeptide having ent-Kaurene synthase activity; a polypeptide having ent-Kaurene oxidase activity; a polypeptide having kaurenoic acid 13-hydroxylase activity; and one or more polypeptides having UDP-glucosyltransferase activity whereby expression of the nucleotide sequence(s) confer(s) on the microorganism the ability to produce at least one steviol glycoside. The present invention also relates to a composition comprising steviol glycosides obtainable by such a method.
Production of Steviol Glycosides in Recombinant Hosts
The invention relates to recombinant microorganisms and methods for producing steviol glycosides and steviol glycoside precursors.
Efficient Production of Steviol Glycosides in Recombinant Hosts
Recombinant microorganisms are disclosed that produce steviol glycosides and have altered expression of one or more endogenous transporter or transcription factor genes, or that overexpress one or more heterologous transporters, leading to increased excretion of steviol glycosides of interest.
Methods for production of oxygenated terpenes
The present disclosure relates to methods for producing oxygenated terpenoids, and preparation of compositions and formulations thereof. Polynucleotides, derivative enzymes, and host cells for use in such methods are also provided.
Geranylgeranyl pyrophosphate synthases
The present invention relates a variant polypeptide having geranylgeranyl pyrophosphate synthase activity, which variant polypeptide comprises an amino acid sequence which, when aligned with a geranylgeranyl pyrophosphate synthase comprising the sequence set out in SEQ ID NO: 1, comprises at least one substitution of an amino acid residue corresponding to any of amino acids at positions 92, 100 or 235 said positions being defined with reference to SEQ ID NO: 1 and wherein the variant has one or more modified properties as compared with a reference polypeptide having geranylgeranyl pyrophosphate synthase activity. A variant polypeptide of the invention may be used in a recombinant host for the production of steviol or a steviol glycoside.
