Abstract

An inhibitor of sweet potato acid invertase (EC 3.2.1.26) was found in fresh sweet potato root tissue, and partially purified. The inhibitor is possibly a thermostable protein with a molecular weight of about 19, 500. The inhibitory activity is highly specific to acid invertase. The inhibitor binds to the enzyme reversibly in a noncompetitive way, inhibiting the enzyme activity.
