The direction shown, i.e. which substrates are on the left and right sides, is in accordance with the Enzyme Commission system.
Most BioCyc compounds have been protonated to a reference pH value of 7.3. Please see the PGDB Concepts Guide for more information.
Mass balance status: Balanced.
Enzyme Commission Primary Name: geraniol dehydrogenase (NADP+)
Standard Gibbs Free Energy (ΔrG'° in kcal/mol): -0.25653076 [Latendresse13]
Enzyme Commission Summary:
The enzyme 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.
Instance reaction of [an alcohol + NADP+ = an aldehyde + NADPH + H+] (22.214.171.124):
i1: geraniol + NADP+ → geranial + NADPH + H+ (126.96.36.199)
