ENZYMES FOR BIOCONVERSION OF CHLOROGENIC ACID IN AT LEAST ONE DI-, TRI- OR TETRA-CAFEOYLQUINIC ACID

摘要

The present invention relates to proteins capable of converting chlorogenic acid into at least one di-, tri- or tetra-cafoylquinic acid, comprising an amino acid sequence selected from SEQ ID NO: 8 to SEQ ID NO: 18, sequences homologous to these specific sequences, or fragments of such sequences retaining the conversion activity of chlorogenic acid into at least one di-, tri- or tetra-caffeoylquinic acid. It also relates to isolated nucleic acid molecules encoding such proteins, as well as expression vectors of these sequences, host cells, and transgenic plants. It also relates to the use of these proteins, expression vectors, host cells, or transgenic plants for converting chlorogenic acid into at least one di-, tri- or tetra-cafoylquinic acid, as well as various production processes. at least one di-, tri- or tetra-cafoylquinic acid from chlorogenic acid.
