Origin: Formed within English, by derivation; perhaps modelled on a German lexical item. Etymons: myrosin n., -ase suffix.

Etymology: < myrosin n. + -ase suffix, perhaps after German Myrosinase (c1930, F. Wrede in Handb. der biol. Arbeitsmethoden Lieferung 317).

Biochemistry.

An enzyme present in certain plants which catalyses the hydrolysis of sinigrin and other sulphur-containing glycosides (e.g. in reactions occurring when tissue is damaged). Also called myrosin.

1958 Arch. Biochem. & Biophysics 75 235 It..appears that hydrolysis of sinigrin by sinigrase..or by myrosinase yields allylisothiocyanate.

1972 Biochimica et Biophysica Acta 276 508 The glucosinolates occur in all Cruciferae and seem always to be accompanied by myrosinases.

1997 Proc. National Acad. Sci. U.S.A. 94 10367/2 Isothiocyanates..are synthesized and stored in plants as relatively stable precursors, known as glucosinolates.., which are hydrolyzed to isothiocyanates by myrosinase.
