EC 1.1.1.183     
Accepted name: geraniol dehydrogenase (NADP+)
Reaction: geraniol + NADP+ = geranial + NADPH + H+
Systematic name: geraniol:NADP+ oxidoreductase
Comments: Also acts, more slowly on farnesol but not on nerol. The enzyme produces a mixture known as citral, which includes geranial and neral. It is still not known whether neral is produced directly by the enzyme, or by isomerization of geranial.
