prunasen.

Brit.

/ˈpruːneɪz/,

/ˈpruːneɪs/, U.S.

/ˈpruˌneɪz/,

/ˈpruˌneɪs/

Origin: A borrowing from Latin, combined with an English element. Etymons: Latin Prunus , -ase suffix.

Etymology: < scientific Latin Prunus, genus name ( < classical Latin prūnus : see prunus n.) + -ase suffix (see quot. 1912).

Biochemistry.

An enzyme which hydrolyses β-glucosides (notably prunasin), liberating glucose, and occurs chiefly in bitter almonds and yeast, as well as in the fruit of several trees of the genus Prunus.
