Isolation and characterization of acid invertase inhibitor from sweet potato.
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 non-competitive way, inhibiting the enzyme activity.
