Abstract:

A kinetic analysis of the inhibition of human salivary alpha-amylase (EC 3.2.1.1) by wheat seed (Triticum aestivum) type II alpha-amylase inhibitor revealed the inhibition was slow and tight-binding. The inhibition was competitive with an inhibition binding constant of the alpha-amylase inhibitor for alpha-amylase of 0.29 nM. The KM of alpha-amylase for soluble starch (calculated per mole of alpha-1,4 linked maltose residues) was 5.87 mM.
