Abstract
The purpose of the present invention is to provide a protein, said protein having an activity of synthesizing rhamnose from glucose, and a polynucleotide encoding the same. Provided are a rhamnose synthase derived from stevia and a method for producing rhamnose from glucose using a gene. Also provided is a method for producing a steviol glycoside using the rhamnose synthase derived from stevia.
Claims8
A method comprising reacting, outside of a stevia plant, glucose and the protein according to any one selected from the group consisting of the following (a) to (c) to produce rhamnose:
- (a) a protein consisting of the amino acid sequence of SEQ ID NO:
- 2, 4, 6, 8, or 10;
- (b) a protein consisting of an amino acid sequence wherein 1 to 13 amino acids are deleted, substituted, inserted, or added in the amino acid sequence of SEQ ID NO:
- 2, 4, 6, 8, or 10 and having an activity to produce rhamnose from glucose;
- (c) a protein having an amino acid sequence having a sequence identity of 98% or more to the amino acid sequence of SEQ ID NO:
- 2, 4, 6, 8, or 10 and having an activity to produce rhamnose from glucose.
