Abstract

The enzymatic basis for quinine 1 biosynthesis was investigated. Transcriptomic data from the producing plant Cinchona pubescens led to the discovery of three enzymes involved in early and late steps of the pathway. A medium-chain alcohol dehydrogenase (CpDCS) and an esterase (CpDCE) yielded the biosynthetic intermediate dihydrocorynantheal 2 from strictosidine aglycone 3. Additionally, the discovery of an O-methyltransferase specific for 6´-hydroxycinchoninone 4 suggested the final steps order to be cinchoninone 16/17 hydroxylation, methylation and keto-reduction.

Methods

This transcriptomic dataset was acquired from Cinchona pubescens. Illumina data were acquired, assembled and annotated by BGI-seq.
