The present paper describes the effect of allyl isothiocyanate (which is a hydrolysis product of sinigrin, a glycoside found in Wasabia japonica) on the activity of barley β-amylase, selelcted because the same enzyme existing abundantly in other plants is not purified.It was found that β-amylase activity was strongly inhibited by the addition of allyl isothiocyanate in alkaline medium, and was decreased by the addition of PO4^<3-<. The inhibited activity could not be recovered by the addition of reactivators such as cysteine and BAL. Therefore the mechanism of this inhibition may be different from the inhibition caused by the additio of PCMB. According to the finding of the effect from the addition of isothiocyanates or related compouds on β-amylase, this inhibition may be thought to be due to NCS group of molecules.
