Accepted name: agroclavine dehydrogenase
Reaction: agroclavine + NADP+ = 6,8-dimethyl-6,7,8,9-tetradehydroergoline + NADPH + H+

Glossary: agroclavine = 6,8-dimethyl-8,9-didehydroergoline
Other name(s): easG (gene name)
Systematic name: agroclavine:NADP+ oxidoreductase
Comments: The enzyme participates in the biosynthesis of ergotamine, an ergot alkaloid produced by some fungi of the Clavicipitaceae family. The reaction is catalysed in the opposite direction to that shown. The substrate for the enzyme is an iminium intermediate that is formed spontaneously from chanoclavine-I aldehyde in the presence of glutathione.
