EC Number:

Enzymes and Genes:

Escherichia coli K-12 substr. MG1655: aldehyde reductase, NADPH-dependent: yahK
aldehyde reductase, NADPH-dependent: ahr
NADP+-dependent aldehyde reductase: ybbO
NADPH-dependent aldehyde reductase: yqhD
Ocimum basilicum: geraniol dehydrogenaseInferred from experiment: GEDH1
geraniol dehydrogenaseInferred from experiment: CAD1

In Pathway: geraniol and geranial biosynthesis

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): -0.25653076Inferred by computational analysis [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.
