  • ENZYME FOR THE CONVERSION OF CHLOROGENIC ACID INTO ISOCHLOROGENIC ACID
    Publication number: 20230148181
    Abstract: A protein capable of converting chlorogenic acid into isochlorogenic acid. The protein includes or is an amino acid sequence SEQ ID No. 1, a sequence having at least 80% identity with this sequence or a fragment of this sequence. Also, a process for producing isochlorogenic acid from chlorogenic acid, which includes producing the protein and bringing it into contact with chlorogenic acid.

  • Use of a virus DNA as promoter
    Patent number: 6303345
    Abstract: Described is the characterization and the use of strong viral promoters for expressing genes, in bacteria and fungi, in particular yeasts. The invention is based on the surprising finding that CFDV DNA (coconut foliar decay virus DNA) and CFDV DNA fragments contain a region which is active as promoter even in bacteria and fungi, in particular yeasts, although they are derived from a virus which infects monocotyledonous plants. The activity of the promoters described in E. coli is distinctly higher than that of the CaMV 35S promoter, which is also active in bacteria.
