A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 1.1.1.105

Accepted Name
All-trans-retinol dehydrogenase (NAD(+)).
Reaction catalysed
All-trans-retinol-[cellular-retinol-binding-protein] + NAD(+) <=> all-trans-retinal-[cellular-retinol-binding-protein] + NADH
Comment(s)
  • The enzyme recognizes all-trans-retinol and all-trans-retinal as substrates and exhibits a strong preference for NAD(+)/NADH as cofactors.
  • Recognizes the substrate both in free form and when bound to cellular-retinol-binding-protein (CRBP1), but has higher affinity for the bound form.
  • No activity with 11-cis-retinol or 11-cis-retinal (cf. EC 1.1.1.315).
  • Also active with 3-alpha-hydroxysteroids.
