linamarase


Also found in: Wikipedia.

linamarase

an enzyme in the plants Linum spp. which liberates hydrocyanic acid from a cyanogenetic glycoside in the same plant. Boiling for 10 minutes destroys the enzyme and renders the material, usually linseed, safe.

Hydrolysis of these glucosides is catalyzed by a [beta]-glucosidase, linamarase and yields glucose and acetone cyanohydrins (Santana et al.
During the consequent fermentation, roots are softened, the disintegration of the tissue structures result in the contact of linamarin with linamarase and subsequent hydrolysis to glucose and cyanohydrins which easily break down to ketone and hydrocyanic acid (Cooke, 1978).
Peeling may be an efficient way of reducing the cyanide content of cassava tubers; however, the peel contains a higher endogenous linamarase level than the pulp (Wood, 1966).
For unpeeled cassava fermentation, endogenous linamarase and microbial linamarase might have contributed to a faster reduction of the total cyanide content of the fermenting cassava tubers (Figure 4).
The linamarase of Leuconostoc mesenteroides: production, isolation and some properties.
The plants contain an enzyme, called linamarase, which is capable of generating cyanide when animals or insects cause damage to the plant, thereby deterring further attacks.
5 mL of urine, buffered at pH 8, 40 [micro]g of linamarin and different amounts of linamarase were added, followed by a picrate paper.
