The method is for example useful for determining the limit dextrinase activity in a sample.

The process of the invention includes heating a cell homogenate at 4OºC, in the presence of divalent cations thus increasing the specific activity of the limit dextrinase.

Also provided are a nucleotide sequence and protein of the limit dextrinase inhibitor gene, and plant and plant parts produced by the method of the invention.

The most important brush border enzymes are dextrinase and glucoamylase which further break down oligosaccharides.
