General annotation (Comments)

Function

Involved in cyanogenesis, the release of HCN from injured tissues. Catalyzes the stereospecific addition of HCN to a variety of aldehydes in vitro. It is a major seed constituent, and could have the additional role of a storage form for reduced nitrogen By similarity.

Catalytic activity

(R)-mandelonitrile = cyanide + benzaldehyde.

Cofactor

FAD.

Subunit structure

Monomer.

Subcellular location

Vacuolealeurone grain By similarity. Note: Primarily found within protein bodies of the cotyledonary parenchyma cells, with lesser amounts within the procambium By similarity.

Sequence similarities

Belongs to the GMC oxidoreductase family.
