    Publication number: 20230039694
    Abstract: Disclosed in the present invention is a hyoscyamine aldehyde reductase (HAR) and uses thereof. The hyoscyamine aldehyde reductase has an amino acid residue sequence as shown in SEQ ID NO. 4 and a nucleotide sequence as shown in SEQ ID NO. 3. After prokaryotic expression of the hyoscyamine aldehyde reductase, a product of a catalyzed hyoscyamine aldehyde reduction reaction is hyoscyamine. After the hyoscyamine aldehyde reductase is used for converting Atropa belladonna, the content of hyoscyamine in an Atropa belladonna cell line can be increased, which has important significance in increasing the content of tropane alkaloids in Atropa belladonna.
