ALDH1A2

Functionⁱ

Recognizes as substrates free retinal and cellular retinol-binding protein-bound retinal. Does metabolize octanal and decanal but does not metabolize citral, benzaldehyde, acetaldehyde and propanal efficiently (By similarity).By similarity

Catalytic activityⁱ

Retinal + NAD⁺ + H₂O = retinoate + NADH.

Pathwayⁱ: retinol metabolism

This protein is involved in the pathway retinol metabolism, which is part of Cofactor metabolism.
View all proteins of this organism that are known to be involved in the pathway retinol metabolism and in Cofactor metabolism.
