Chromatographic methods for amylases

This review surveys recent developments in chromatographic methods for the separation of amylases from complex extracts, including the separation of isozymes. It contains two tables with the properties and molecular characteristics of alpha-and beta-amylases from different sources as well as an updated review of methods for the determination of amylase activity. The main subject of this review is a detailed evaluation of the application of newly developed chromatographic methods for the purification of amylases.

Purification and characterisation of limit dextrinase from Pisum sativum L

A limit dextrinase has been purified 2,700-fold from ungerminated pass by affinity chromatography. The enzyme hydrolyses (1 yield 6)-alpha-d-glucosidic linkages in alpha-limit dextrins containing at least one alpha-1(1 in alpha 4)-linked d-glucose residue on either side of the susceptible linkage. The limit dextrinase also hydrolyses the polysaccharides amylopectin, amylopectin beta-limit dextrin, glycogen beta-limit dextrin, and pullulan, but has no activity towards glycogen.
